- Drown adjusting pins in the block of cylinders.
- Turn off bolts of fastening of a cover to the block of cylinders, lower a cover for separation of laying of a head of cylinders (try not to damage laying) and remove it.
- Turn a bent shaft to an exit of the piston of the 1st cylinder in VMT that corresponds to a combustion phase (a tag on the forward bearing of the camshaft).
- Remove a pusher of a natyazhitel of a chain.
- Remove uspokoitel, a boot and a natyazhitel of a chain.
- Remove one of chain links, having cut with an abrasive circle of its axis.
- Remove a chain from asterisks.
- Check a condition of asterisks, uspokoitel, a natyazhitel of a chain.
Installation of a chain
Installation of the directing chain
Installation of the displaced spline on a camshaft asterisk for compensation of an extract of a chain.
Arrangement of the aligning camshaft drive cover pins on the block of cylinders
Removal of an asterisk of the drive of the camshaft
At installation of a pulley of a bent shaft direct a convex part of three dish-shaped washers to a pulley
- Check position of the piston of the 1st cylinder in VMT and position of the camshaft.
- Put on a new chain asterisks, having directed safety washers of quickly connecting link towards a camshaft drive cover.
- Install uspokoitel of a chain, a boot and press the piston of a natyazhitel of a chain.
Insignificant shift of the camshaft in relation to a bent shaft can be eliminated with installation of the displaced spline on a camshaft drive asterisk.
- Check a condition of the oil pump and replace epiploons.
- Cut paper laying of a cover of the drive of the camshaft in places of a gap.
- Grease laying with special glue and put it into place.
- Pull out the aligning pins from the block of cylinders.
- Establish a camshaft drive cover, screw bolts, paying attention to their length and not allowing damage of laying of a head of cylinders.
- Gradually tighten bolts of fastening of a cover.
- Establish a holder of an epiploon of a bent shaft (when replacing an epiploon replace and I will embrace).
- Establish a pulley of a bent shaft and tighten bolts the set moment.
- Fix an arm of an oil receiver and a maslozaborny pipe on the radical bearing of a bent shaft.
- Put new laying of a case of the engine.
- Establish an engine case.
- Install the engine on support, tighten bolts of fastening of arms of an engine mount and the transmission.
- Connect a reception pipe of mufflers to a final collector, fix an arm of a reception pipe on the transmission.
- Install the buffer.
- Install the stabilizer of cross stability.
- Establish an engine guard.
- Install the VMT sensor.
- Install the conditioner compressor, the pump of the hydraulic booster of steering and the generator.

- Install the fan and a radiator.
- Attach hoses and fill in cooling liquid.
- Remove air from the cooling system.
- Turn a bent shaft on two turns for a conclusion of the piston of the 1st cylinder in VMT.
- Make sure that the tag on the camshaft is opposite to the plane of a head of cylinders.
- Establish a cover of a head of cylinders and fill in oil.
- Install the ignition sensor distributor.
- Check idling of the engine, installation of the moment of ignition and be convinced of lack of a leak of oil and cooling liquid.
