Removal Procedure

Start By:

Note: If all connecting rod bearings require replacement, the procedure can be carried out on two cylinders at the same time. The procedure can be carried out on the following pairs of cylinders. 1 with 4 and 2 with 3. Ensure that both pairs of the connecting rod bearings are installed before changing from one pair of cylinders to another pair of cylinders. Refer to Disassembly and Assembly, "Connecting Rod Bearings - Install" for the correct procedure.
