Bearing Refitment with the Piston not Removed
In the case of piston and big-end bearing not being removed, lift and support big-end bearing with square
timber, insert bearing shell (1) as described under "Bearing Refitment with Piston Removed", and slowly turn
crankpin into head. Remove square timber.
Clean cap (5) and shell (4) and apply oil to shell inside. Check that shell back and joints are free from oil or
grease, otherwise heat transfer may be affected. Install cap (5) with shell (4). Fix bearing cap in place with
prallel pins (2).
Screw in connecting rod bolts (6) with washers (7) and tighten crosswise (Section 3.5, item 04).
If necessary, measure bearing running clearance (Job Card 02.03.03).
The rod side clearance should be as follows:
New Condition Wear Limit
0,40 - 0,64 mm 0,75 mm
For running in new or used bearing shells, see Section 4.6.
When performing the job above, be careful not to foul the piston coolant nozzles (Job Card 02.15.01).
