Tools Required

1. Mark the connecting rod cap and the connecting rod for proper installation.

Notice: If there is a pronounced ridge at the top of the piston travel, the ridge must be removed with a ridge reamer before the piston and connecting rod assembly are removed. Applying force may break the piston rings or damage the piston.

2. Use the J 24270 to remove the cylinder bore ring ridge.

2.1.	Turn the crankshaft until the piston is at the bottom of the stroke.

2.2.	Cover the piston with a cloth.

2.3.	Remove the cylinder ring ridge.

2.4.	Turn the crankshaft until the piston is at the top of the stroke.

2.5.	Remove the cloth.

2.6.	Remove the metal shavings from the cylinder and piston.




3. Remove the connecting rod bolts.
4. Remove the connecting rod cap.



5. Install J 41507 to the connecting rod. Hand tighten the tool to the connecting rod.
6. Use hand pressure on J 41507 to push the connecting rod towards the top of the cylinder.

Important: Mark the piston with the number of the cylinder from which it was removed. Mark the piston as to what is the front for proper reassembly.

7. Remove the piston, the connecting rod, and the connecting rod bearings.
