The topic of the article is the timing belt ZMZ 406. We will talk about a set with double-row chains. When a standard car arrives to replace the timing belt, this is one thing. When an UAZ patriot arrives on 33 wheels or a medical gazelle with a ton of equipment on top of the dry mass, this is different. To the question what to put? Single-row chain, double-row, or leave the wonderful tooth-and-plate design? The answer is unambiguous: two-row chains. But a stalemate has come on the market, when there is nothing decent, but cars need to be made. For this reason, the timing kit ZMZ 406, 405, 409 was born, which I bring to your attention.
Timing belt ZMZ 406, situation
On these engines, with my own hands, I changed several dozen timing belts and have a fairly good idea of the situation in my region (St. Petersburg and the surrounding area). The fact that clients brought in "factory boxes" or with magical names of a double and tenth resource, I certainly set, but I took a receipt from people in which I warned that I did not like the quality even visually. Very often they brought kits from the Progress company. But they have their own problem. Almost every set was individual. There were no identical sets. Either different manufacturers of chains, or not the gears that were "yesterday". Accordingly, the quality floats like a "violet in the hole." Rusmash produces good sets, but they don't make adjustable sprockets. The best, in my opinion, are the Rhodes-M kits (Medvedev I.A.), but unfortunately they are poorly available for logistical reasons. Today there is, and then a couple of months there may be a failure in the supply. Sometimes more. Based on these reasons, it was decided to assemble a kit for customers and services, which can be given a decent guarantee, and most importantly, meets modern technical requirements. And he also tried to implement what was asked from all over Russia. The kit should include EVERYTHING that may be needed for replacement, including the cuff, gaskets, half rings, and even additionally can be ordered. That is, in order to overhaul the gas distribution mechanism and forget about it for a very long time.
Timing belt ZMZ 406, my version
- 4 stars (rusmash). .
- Tensioner shoes (Rusmash or Rhodes-M)
- Tensioners 2 pcs. (Rusmash)
- Euro-2 sedatives
- crankshaft seal
- Gasket set (pump and tensioner gaskets, 2 chain cover gaskets)
In the extended version, the kit is supplemented with a bottle of brake cleaner, sealant and a medium thread locker. This is all that I use when replacing timing belts on these engines. A lot of this list I have already painted separately on the pages of the site. I will dwell on those points that have not previously been met or are quite important when replacing timing belts.
Of the spare parts, you may need a pump and a promval. But if the pump can then always be installed in a couple of hours, then the replacement of the promval, this is a new, complete disassembly of the timing. Therefore, if the engine mileage is close to a hundred or more, find out in advance which store has a quality spare part. If you don’t need it, it’s good, if you need it, you will know where to buy it. The kit was run in an ambulance. The audit was carried out at 50 and 100 thousand kilometers. On the ambulance with the speed of running around the clock, there are no problems)) Most of all I was interested in "chain extraction". The camshafts “ran away” for a given run by 1-2 degrees from the initial installation. which is within the margin of error. This result satisfied me.
Question answer
- What kind of warranty do you provide for this kit?
When I install this kit with my own hands, I give a guarantee from 3 months to six months without mileage limitation, depending on the rest of the engine condition. Of course, when it comes to our boundless homeland, such guarantees would be stupidity on my part. But I hope that this displays for customers the approximate reliability of the kit.
- Is it possible or not to purchase part of this kit?
Maybe. For example, a client wants to re-riveted Mercedes chains, put other sprockets or tensioners. In this case, the price of the kit is calculated individually and, of course, there can no longer be any guarantees on my part.
- Are the components in this set changing or not?
As I said above, this approach of other manufacturers personally annoys me and causes misunderstanding. Therefore, the main components of this set are unchanged. For a year of sales, compared to the primary photo, I only changed the chain tensioners. Replacing the tensioners with a wear indicator in the kits with ordinary ones without an indicator (of the same manufacturer). This was due to sound logic, why are there wear indicators on the new “zero” double-row chains? Which may be needed after a few years of operation. Yes, and the pricing of the kit is also an important thing.
Engine UAZ Patriot 409 from the Zavolzhsky Motor Plant have recently been brought up to the Euro-4 environmental standard. In fact, this is an injection 406 engine, which was installed on the Volga and GAZelles. The actual design of the power units is very similar, in addition, the ZMZ 409 engine also inherited the problems of the 406 motor. Next, we offer a description and UAZ Patriot 409 engine specifications.
The petrol, in-line, 4-cylinder and 16-valve unit has a cast-iron cylinder block and an aluminum cylinder head. There are two camshafts in the head of the block, which rotate by means of a timing chain drive. There are hydraulic compensators in the valve mechanism, which free you from manually adjusting the thermal clearance of 16 valves.
The device of the gas distribution mechanism of the engine ZMZ 409 UAZ Patriot
The camshafts are cast iron. To achieve high wear resistance of the working surface, the cams were “chilled”. The shafts rotate in bearings formed by the cylinder head and removable aluminum covers. These covers are machined complete with the cylinder head and are therefore not interchangeable. Camshaft drive chain, two-stage. Includes: crankshaft sprocket 1, intermediate shaft driven sprocket 5 and drive 6, camshaft driven sprockets 12 and 14, two chains (72 and 92 links) 4 and 9, hydraulic tensioners with reinforced spring 2 and 8, tensioner levers 3 and 7 and chain dampers 13, 16 and 17. The chain tension of each stage is carried out by hydraulic tensioners located: one on the front cover of the cylinder block (chain cover), the other on the cylinder head.
- 1 - crankshaft sprocket
- 2 - lower hydraulic tensioner
- 3 – lower chain tensioner lever
- 4 - lower chain
- 5 - an asterisk of an intermediate shaft driven
- 6 - an asterisk of an intermediate shaft leading
- 7 - upper chain tensioner lever
- 8 – upper hydraulic tensioner

Perhaps it is complex mechanism of the timing device 409 of the UAZ Patriot engine causes a lot of trouble when operating the engine. The lack of oil pressure quickly disables hydraulic lifters, you must carefully monitor the oil level in the engine. And frequent breakdowns of the chain tensioners cause an unpleasant sound. The problem is solved by installing imported hydraulic tensioners and regular replacement of high-quality oil. It should be noted that the valves are interchangeable with similar valves of the VAZ-2108 engine. Further characteristics of the gasoline engine UAZ Patriot.

This engine is very voracious, this is perhaps the main problem of the Patriot with this power unit at the moment. A rather outdated design will not please you with its reliability. However, the price of the new UAZ Patriot makes us turn a blind eye to such disadvantages.
In engines of the ZMZ-409 family, depending on the year of manufacture and engine modification, there are differences in the camshaft drive. It can be used with single or double row sleeve chains or single row toothed chains. There are some differences in the camshafts themselves.
Timing camshaft drive of the ZMZ-40905 engine.
The drive of the camshafts of the ZMZ-40905 engine consists of a crankshaft sprocket with 29 teeth, driven by 46 teeth and leading by 23 teeth of the intermediate shaft sprockets, sprockets with 29 teeth of camshafts, two gear chains: lower - 84 links. top 108 links, hydraulic tensioners, chain tension shoes and chain guides. The tension of the chain of each step is carried out by hydraulic tensioners.
For the correct assembly of the camshaft drive and the installation of the valve timing, there are marks on the crankshaft sprocket, the intermediate shaft driven sprocket, and the camshaft sprockets.
When installing the drive, the marks M1, M2 on the cylinder block must match the marks on the sprockets of the crankshaft and intermediate shaft. The marks on the camshaft sprockets should be directed in different directions to the outside of the engine and coincide with the upper plane of the cylinder block.
This position of the camshafts and crankshafts corresponds to the presence of the piston of the first cylinder at the TDC of the compression stroke. The position of the piston of the first cylinder at TDC can also be determined by the coincidence of the marks on the damper disc of the crankshaft pulley with the protrusion on the chain cover.
The inlet and outlet camshaft sprockets of the timing chain drive are not interchangeable. To distinguish them from each other, two alignment marks are stamped on the intake camshaft sprocket, there is only one mark on the exhaust camshaft sprocket.
The intermediate shaft drive sprocket is steel, carbon-nitrided to increase hardness and wear resistance. The sprockets of the crankshaft, camshafts and the driven sprocket of the intermediate shaft are made of ductile iron.
Timing camshaft drive of the ZMZ-40904 engine.
The camshaft drive of the ZMZ-40904 engine is the same as on the ZMZ-40905 engine, with the exception that on the ZMZ-40904.10 engines of early releases, the camshaft drive was used not on toothed chains, but on two single-row or double-row sleeve chains: lower - 72 links, the top - 92 links, and tensioners with an asterisk instead of chain tension shoes. That is, the same as previously on the ZMZ-409.10 engine.
Timing camshaft drive of the ZMZ-40911 engine.
The camshaft drive of the ZMZ-40911 engine is the same as on the ZMZ-40904 and ZMZ-40905 engines. Differences in the drive of the camshafts concern only the camshafts themselves.
Replacement of single-row sleeve chains for timing camshafts ZMZ-409 with double-row or gear chains.
When replacing single-row sleeve chains of the camshaft drive with double-row chains, it is necessary to replace all sprockets, hydraulic tensioners and tensioners with sprockets, and when replacing them with toothed chains, it is necessary to change all sprockets, chain guides, and instead of tensioners with an asterisk, put chain tension shoes.
Replacement of double-row sleeve chains for timing camshafts ZMZ-409 with toothed chains and vice versa.
When replacing double-row bush chains of the camshaft drive with gear chains or vice versa, gear chains with double-row bush chains, all sprockets, chain dampers, hydraulic tensioners must be replaced. Sprocket tensioners change to chain tension shoes or vice versa.
Camshafts of the gas distribution mechanism ZMZ-40904, ZMZ-40905 and ZMZ-40911.
Camshafts of all engine models are cast from special alloyed cast iron. To achieve high wear resistance of working surfaces, the cams are chilled. The shafts rotate twice as slowly as the crankshaft in bearings formed by the cylinder head and removable aluminum covers.
The camshafts are held against axial movement by polyamide half-rings that fit into the grooves on the front bearing journal of the shafts and the front cover of the camshafts.
In engines ZMZ-40904 and ZMZ-40905 The intake and exhaust camshafts have the same cam profile and provide 9mm of valve lift.
On the engine ZMZ-40911 The intake and exhaust camshafts have different cam profiles and provide 8mm of inlet valve lift and 9mm of exhaust valve lift.
A metal plate is fixed on the rear end of the exhaust camshaft, which serves to supply impulses
Many experienced motorists argue that the replacement of the timing belt with a UAZ Patriot diesel Iveco should be carried out every hundred thousand kilometers. This figure is approximate and largely depends on how the vehicle was operated.
Some models have a timing chain. It is alleged that its resource is greater than that of the belt, but this is not always the case. As practice shows, in some cases the need for replacement occurs after fifty thousand kilometers. In any case, the time to replace the chain must be determined by its condition and regularly checked visually for damage and loose tension. Also, is there any damage to the tension rollers.

Replacement cases
The timing belt on the UAZ Patriot on an Iveco diesel must be changed if the mileage specified in the instructions is reached. If oil stains, worn teeth or delaminations are found.
Step by step instructions for replacing the belt
The change process is simple, but it will require the removal of additional nodes and some rollers, so be careful.
Tools
- a set of keys;
- new tension rollers (they may need to be changed);
- screwdriver.
Stages
- First you need to remove the generator and air conditioning compressor.
- Having unscrewed the fasteners, you need to release the generator, and then take it away so as not to interfere.
- Now you need to unscrew and remove the fan impeller. We also remove the diffuser.
- We remove the fan drive by unscrewing the locknut under the manifold.
- Now you need to remove the bypass roller and tensioner.
- Next, remove the tensioner.
- We remove the pulley from the crankshaft, after unscrewing the four bolts.
- Remove the cover of the gas distribution mechanism.
- Rotate the crankshaft clockwise. It is necessary that the mark on the crankshaft becomes at 9.00, and on the distributive, at 12.00.
- Next, you need to fix the shafts.
- To fix the crankshaft, you need to unscrew the plug, and insert a screwdriver into the hole.
- Many motorists fix the camshaft with a drill of a suitable diameter inserted into the pulley hole.
- Now you need to unscrew the tensioner bolt and remove it.
- Next, you can remove the belt.
- We proceed to the final stage of installing a new timing belt.
- When installing a new one, we make sure that its marks coincide with the marks on the crankshaft at 9.00, and also with the mark on the camshaft pulley at 12.00.
- Install the tensioner.
- When pulling the belt, you need to make sure that the point coincides with the cutout or goes under tension.
- We put the removed parts in place, while do not forget to lubricate the rollers.

Stages
Metal products from China have never been particularly reliable, this also applies to tension rollers.
Work on replacing a belt or chain on a UAZ is not difficult in itself, but it requires certain skills and attention. Therefore, it will be useful if a more experienced partner will insure you for the first time. Also, if you are unsure of your own abilities and are afraid that you can confuse something, film the disassembly process on camera. Then it will be easier to collect. Place the removed parts in pre-prepared boxes and jars. It often happens that some bolt, roller or washer gets lost, so be careful and attentive.
In the future, when operating the car, try to follow all the routine measures specified in the instructions that come with the car. Timely pass diagnostics at the service station and your car will work properly and smoothly for many years.

The gas distribution mechanism on the engine of the UAZ Patriot car performs the function of synchronizing the crankshaft and camshaft, and also sets the cycles for opening and closing valves. The efficiency of the engine, its trouble-free and reliable operation depend on its operation. That is why the operation of the timing system of the UAZ Patriot engine is very responsible. So, to increase the reliability of the timing mechanism, a chain drive was used, but even it can stretch or even break over time. As a result, individual parts and the timing chain itself must be replaced approximately every 80,000 km. Here it is impossible to say about the exact mileage, since it will depend on the operating conditions of the engine. If the engine is running for wear, the chain may need to be replaced earlier. Chain wear will manifest itself in its "clatter" - a high-frequency sound like from valves. In this article, we will just provide information on replacing chains and gears of the gas distribution mechanism. It is noteworthy that the UAZ Patriot timing mechanism uses 2 chains, conditionally lower and upper. Such a timing mechanism can be considered difficult to maintain, so replacing the chains will require advanced skills from the mechanic who will carry out the work.The process of replacing timing chains ZMZ 409 Euro 3
Before starting work on the engine, it is necessary to remove the radiator and drive belts for the power steering pump of the generator and the pump. Loosen the clamp of the supply hose to the cooling system pump and remove the hose from the fitting. Remove the cylinder head cover. Turn out four bolts and remove a forward cover of a head of the block of cylinders in gathering with the coupling of a drive of the fan and the fan (the viscous coupling with the fan are removed for descriptive reasons). Remove the water pump Remove the crankshaft speed sensor (timing sensor) Remove the crankshaft pulley (see "Replacing the crankshaft oil seals UAZ Patriot"). Remove the oil sump (see "Replacing the crankcase of the UAZ Patroit engine"). Turn out two bolts and remove a cover of a hydraulic tensioner of the top chain with a lining. Remove the cover carefully, as it is affected by the hydraulic tensioner spring. Then remove the hydraulic tensioner Also remove the lower chain tensioner. Turn out 7 bolts and remove a cover of a chain. Remove the cover carefully so as not to damage the front crankshaft oil seal installed in it, the cover gaskets and the cylinder head gasket. Remove 1 top tensioner bolt and remove tensioner arm with sprocket. Also remove the lower tensioner arm. Also with an asterisk. Remove the 2 bolts and remove the plastic chain guide. Remove the gears from the camshafts by unscrewing the bolts securing the gears to the camshaft flanges. Here you will need a puller. Turn out bolts 2 and take up a guide 1 chains. Bend the ends of the locking plate 6 and unscrew the bolt 5, for which keep the intermediate shaft from turning by inserting a screwdriver into the hole of the gear 3. Remove the gear 4 by inserting a screwdriver between it and the gear 3 and resting the screwdriver as a lever against the gear 3. Remove the gear 4 from the top chain and remove the chain by pulling it up. Remove gear 3 from the intermediate shaft and remove it from the lower chain. Remove the lower chain from the crankshaft gear.
If it is necessary to remove gear 2 from the crankshaft, first remove bushing 1 and the rubber o-ring between bushing and gear. Then compress gear 2. The gears are removed using a puller.
After removal, wash the chains and gears in gasoline, wipe and dry them. Examine the chains. If cracks, chips, or significant signs of wear are found on the chain bushings, replace the chains. Replace gears that have chipped or chipped teeth. Replace damaged chain guides. The tensioner sprockets must rotate freely on the axles. If the sprocket teeth are chipped or chipped, replace the tensioners.
Assembling the timing mechanism and installing timing chains UAZ Patriot (recommended tightening and preload torques)
If the gear was removed from the crankshaft, press it onto the crankshaft, install the O-ring and bushing. Turn the crankshaft so that mark 1 on the crankshaft gear matches mark 2 on the cylinder block. In this case, the piston of the 1st cylinder will take the TDC position. Install the chain damper 4 without tightening the bolts 3 fastening the damper. Put chain 5 on the crankshaft gear, after lubricating it with engine oil.
Put the chain on the driven gear 1 and install the gear on the intermediate shaft 2 so that the gear locating pin fits into the hole of the intermediate shaft. In this case, mark 4 on the gear must coincide with mark 5 on the cylinder block, and the chain branch passing through the damper 3 must be tensioned.
Install the countershaft drive gear so that its locating pin fits into the hole in the driven gear. Screw in two bolts of fastening of gears of an intermediate shaft, having placed a lock plate under them. Tighten the bolts to a torque of 22–25 N/m (2.2–2.5 kgf/m) and secure them by bending the edges of the lock plate on the edges of the bolt heads. While pressing the tensioner lever, tighten the chain and check the alignment of the marks on the gears and the cylinder block.
Tighten the chain guide bolts.
Lubricate the upper chain with engine oil and then put it on the countershaft drive gear, passing it through the hole in the cylinder head. Put the chain on gear 2 and, turning the exhaust camshaft slightly clockwise, install gear 2 with the chain on it. Pin 8 of the camshaft must enter the gear hole. Screw in a bolt 1. Turn a camshaft a key for a square on a camshaft. Then, turning the camshaft slightly counterclockwise, tension the chain. The intermediate and crankshafts must not rotate. Mark A must align with the top surface of the cylinder head. Turn out a bolt 6 and remove a gear wheel 4 from an inlet camshaft. Put a chain on gear 4 and install gear 4 with chain on the camshaft by slightly turning the camshaft clockwise. The pin 5 of the camshaft must enter the gear hole. By slightly turning the camshaft counterclockwise, tension the chain. Mark A on gear 4 must match the top surface of the cylinder head. The rest of the shafts must not rotate. Screw in the bolt 6. Tighten the bolts 1 and 6 to 46–74 N/m (4.6–7.4 kgf/m) while holding the camshafts from turning with a wrench on the squares. Install damper 3 by pushing it into the hole in the block head. Install damper 7. Reinstall chain cover and water pump. Spread a thin layer of sealant on the sealing surfaces of the cover and cylinder block and block head. Install the cover carefully so as not to damage the gland. Install the upper and lower chain tensioners, see Assembly (Charging) and Installing the Chain Tensioners . Install the crankshaft pulley. Screw in the bolt securing the crankshaft pulley, then, turning on the fifth gear and braking the car with the parking brake, tighten the bolt to a torque of 104–128 N / m (10.4–12.8 kgf / m), holding the crankshaft from turning. When tightening the ratchet, the pulley is pressed onto the crankshaft. Turn the crankshaft two turns by the ratchet and set the piston of the 1st cylinder to the TDC position (see operation 3). Check if the labels match. Install the front cover of the cylinder head, first apply a layer of Hermesil sealant to the surface of the cover adjacent to the block head. Tighten the cover fastening bolts to a torque of 12–18 N/m (1.2–1.8 kgf/m). Install the cylinder head cover. Tighten the cover fastening bolts to 6.0–12 N/m (0.6–1.2 kgf/m). Connect the crankcase ventilation hose and tube to the fittings on the valve cover, and the wires to the ignition coils. Put on tips of high-voltage wires on spark plugs. Install the previously removed belts and the radiator of the cooling system.
