Piston, Connecting Rod, and Bearing Removal

^ Tools Required
- J 41507 Connecting Rod Guide Assembly
- J 24270 Cylinder Ridge Reamer





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.
1 Turn the crankshaft until the piston is at the bottom of the stroke.
2 Cover the piston with a cloth.
3 Remove the cylinder ring ridge.
4 Turn the crankshaft until the piston is at the top of the stroke.
5 Remove the cloth.
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.

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

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.
