21. Weaken a bolt of the lower support of the generator and turn the generator aside.
22. Give bolts of a support and remove a bracket of support of the generator and support of system of hydrostrengthening of a wheel from a cover of a distributive chain.
23. On B202 engines establish under an oil filter capacity for the spilled oil of suitable volume, then absolutely wipe unions of an oil cooler on a filter casing. Mark the provision of tubes. Give nuts of connecting unions and disconnect tubes of an oil cooler from a casing. Place tubes so that they did not disturb during the work with a cover of a distributive chain.
24. On B202 engines give bolts and remove a pulley from a driving flange of the water pump. The lever unbend a cooler tube from a back wall of the block of cylinders so that it was disconnected from a casing of the water pump. Place a tube so that it did not prevent work with a cover of a distributive chain, and remove a sealing ring.
25. Unscrew and remove the bolts fixing a cover of a distributive chain to the block of cylinders.
26. Unscrew and remove the bolts fixing a cover of a distributive chain to the case pallet.
27. Unscrew and remove the bolts fixing a cover of a distributive chain to a head of cylinders. Pay attention that bolts have various length. Do not pass 2 top bolts on a head of cylinders in 2 lower bolts on the case pallet.
28. Trying not to damage laying of a head of cylinders, carefully uncover a distributive chain complete with the oil pump a crankshaft pin. Where they are applied, remove laying from the block of cylinders.
29. Carefully remove all traces of old laying and sealant from contact surfaces of a cover of a distributive chain, the pallet of a case, a head and the block of cylinders. Make sure that in a flute of the pallet of a case there is no sealant trace left.
30. Remove the oil pump from a cover of a distributive chain (address the Section Removal, survey and installation to the place of the oil pump).

Installation into place

PERFORMANCE ORDER

1. Impose a pillow of suitable sealant on the case pallet. Install new laying on the block of cylinders - if necessary for fixing of laying apply on them a little lubricant. Where laying is not established, apply a pillow of suitable sealant on flanges of a cover of a distributive chain.

2. Carefully install a cover of a distributive chain on the block of cylinders, at the same time carrying out a maslopodayushchy tube of the block of cylinders to an opening of the lower part of a cover of a distributive chain (where it is required).

3. Insert and tighten fixing bolts of a cover of a distributive chain with the required effort. On B202 engines at this stage do not establish fixing bolts of a tube of an oil cooler. Acquire the top and lower bolts fixing a cover of a distributive chain to a head of cylinders and to the case pallet. Make sure that the distance from the end of a maslopodayushchy tube to a flange of the oil pump makes 25 ± 1 mm. Use for this purpose a caliper.

4. On B202 engines establish a new sealing ring for the end of a tube of a cooler, then strengthen it on a casing of the water pump.
5. Install into place the oil pump (address the Section Removal, survey and installation to the place of the oil pump).
6. Tighten with the required effort of 2 top and 2 lower bolts of fastening of a cover of a distributive chain.
