2.8.6.1. Check of technical condition and repair of the engine
Details of the krivoshipno-conrod mechanism
|
Marking of covers of rods and radical bearings |
|
Installation of a cover of the average radical bearing with persistent half rings |
|
Installation of pistons in cylinders. The arrow has to be directed to the bottom of the piston towards the camshaft drive.
|
|
Inhaling of bolts of fastening of covers of rods device for check of a corner of an inhaling |
|
Installation of a back epiploon of a bent shaft
|
|
Installation of device for a press fitting of a forward epiploon of a bent shaft |
|
Installation of a clamp of 102 589 01 40 00th flywheel on the removed engine |
|
Removal of an emphasis of an intermediate shaft of the engine M 102 |
|
Installation of the bearing of a main shaft of the transmission on a bent shaft of the engine M 102
|
|
- Check the size and a condition of a bent shaft.
- Check a condition of inserts of radical bearings. In case of their reuse apply on them tags according to numbering of cylinders.
- Check a pulling and diameter of an exhaust core of bolts of covers of rods and replace them if necessary.
|
- Check interface of covers to rods. Put on a rod cover a bolt in horizontal position against the stop in a rod and be convinced that the cover does not move. Otherwise replace a rod.
|
|
- Check the outer diameter of the piston, a condition of pistons and piston rings. Check a condition of a piston finger and openings under a finger in the piston. On release engines since 1984 check a gap between a rod and the piston.
- Check a condition of bolts of fastening of a flywheel.
- Oil engine inserts of radical bearings and establish them in covers of bearings. Lay a bent shaft in radical bearings. Establish covers of radical bearings.
- Tighten bolts of fastening of covers of radical bearings.
- Check an axial free wheeling of a bent shaft. If it more norm, replace persistent half rings in nests of the average radical bearing.
- Collect pistons with rods, oil engine working surfaces of inserts and establish them in rods and covers of rods. The tag on a cover of a rod has to be directed towards an inlet collector, and the shooter to the piston bottom — towards the camshaft drive.
- Arrange locks of piston rings at an angle 120 °. At the same time they should not be along an axis of a bent shaft and perpendicular to it. At the same time the teflon directing plug of a spring of an oil scraper ring has to be from above the ring lock.
- By means of the device for tightening of piston rings insert into cylinders pistons with rods. Establish conrod covers and tighten bolts of their fastening.
|
- Check a vystupaniye of pistons in VMT over the plane of the block of cylinders.
|
|
- Establish the holder of a back epiploon on a flange of a bent shaft.
- Put on an epiploon adaptation 102 589 00 43 00 and press it in the holder (in spare parts the epiploon with the edge shifted on 3 mm towards the engine to avoid sliding of a working edge of a new epiploon on the surface of sliding of an old epiploon is delivered.
- Establish a gear wheel of a bent shaft, having directed its bore to an adjusting corbel.
- Establish the leading pro-rate of the oil pump.
- Establish an intermediate shaft with a persistent half ring.
- Wrap a lock bolt.
- Install the ignition sensor distributor.
- Establish a boot of a pusher of the tension device.
- Put on a camshaft drive chain.
- Establish the lower uspokoitel of a chain.
- Establish the holder передн го an epiploon of a bent shaft.
- Establish a camshaft drive cover with new laying (pay attention to various length of bolts of its fastening).
- Wrap bolts of fastening of an oil receiver to the 2nd radical bearing.
- Mandrel 102 589 000 14 00 press a new forward epiploon of a bent shaft.
- Insert a spline into a groove of the cranked hall.
- Put a nave of a pulley of a bent shaft.
- Establish an engine case.
- Block a flywheel of a clamp and tighten a bolt of fastening of a pulley with three washers.
- Establish a pulley on a nave.
- Turn a bent shaft to an exit of the piston of the 1st cylinder in VMT.
- Establish a head of cylinders.
- Install the tension device of a chain of the drive of the camshaft.
- Install on the engine an oil filter, the ignition sensor distributor, the generator, the pump of the hydraulic booster of steering, a starter, inlet and final collectors.
