Carefully clean crankpin, top shell (1) and big-end (8). Carefully inspect pin surface and smoothen with an oil
stone any pressure marks that may have been produced in removing the bearing.
Bearing Refitment with Piston Removed
Install piston (Job Card 02.14.01) and lower it until shell can be fitted. Check markings "x" and "y". Apply oil
to running surfaces of shell and pin, but keep shell back and joint free from grease and oil to ensure perfect
heat transfer.
Top and bottom shells being identical, make sure that they are refitted in their original location.
Make sure that lugs (3) of top and bottom shells properly engage in the rod/cap grooves.
Now slowly lower piston/rod assembly down to crankpin. Ensure that the lugs (3) of the top and bottom shells
correctly engage in the rod/cap grooves. Slowly lower connecting rod with the piston onto the crankpin.
