Tools Required

Important: Do not remove the excessive material from the cylinder bore. Excessive removal of material may require cylinder boring to the next oversize.

1. Remove the cylinder bore ridge as necessary.

1.1.	Rotate the crankshaft until the piston is at the bottom of the stroke (BDC).

1.2.	Place a cloth on top of the piston.

1.3.	Perform the cutting operation with a J 24270 . Refer to the manufacturer's instructions before using the J 24270 .

1.4.	Remove the J 24270 .

Important: Place the matching marks or numbers on the connecting rods and the connecting rod caps. The connecting rod caps must be assembled to their original connecting rods.

2. Remove the connecting rod nuts.




Notice: Do not shim, scrape, or file bearing inserts. Do not touch the bearing surface of the insert with bare fingers. Skin oil and acids will etch the bearing surface.

Important: If reusing bearings, keep the bearings with their original connecting rod and connecting rod cap.

3. Remove the connecting rod cap and the lower connecting rod bearing.



4. Install the J 5239 on the connecting rod bolts.



5. Remove the piston, connecting rod and upper connecting rod bearing out of the top of the engine block using the J 5239 .
