Removal and dismantling

1. Removal of pistons and rods requires removal of a head of cylinders and the pallet of a case (and also the oil pump), however it is possible to leave a bent shaft in the block of cylinders. After that pistons and rods are pushed out by means of the hammer handle from the inside of the block of cylinders up after are uncovered bearings of rods and inserts of bearings. Before carrying out this work it is necessary to study the instructions concerning marking, adjusting situation, etc. provided for petrol engines.
2. To separate pistons from rods, it is necessary to remove lock rings of piston fingers. Then to place the piston in hot water (not less than 80 °C) and to beat out by means of the corresponding drift and the hammer. Remove piston rings nippers for piston rings. Check of pistons and rods is made how it becomes on petrol engines, however taking into account the values given in the size table and adjustments. Inserts of bearings of rods are chosen according to values of admissions. Inserts of bearings are marked by figures 1, 2 or 3 and the same figure is beaten out on the outer side of covers of bearings of rods. Surely provide coincidence of both markings.
