J 43650 Balance Shaft Bearing Remover and Installer

Removal Procedure




1. Remove the timing chain, sprocket and tensioner.

Important: DO NOT remove the bolt holding the sprocket.

2. Remove the right (intake) balance shaft bolt (1).




3. Remove the right (intake) balance shaft.





Notice: Proper centering of the tool is required on the balance shaft bushing. If the tool is not properly centered then damage to the bearing bore and block will occur.

4. Install the J 43650 into the balance shaft hole. Insert the tool with the foot parallel to the shaft.




5. When the J 43650 is inserted in the block, turn the J 43650 so that the foot becomes perpendicular to the shaft.
6. Center the foot of the J 43650 on the balance shaft bushing.
7. Once the J 43650 is centered on the balance shaft bushing, then insert the centering guide into the front balance shaft bore and tighten the nut with an appropriate wrench.
When the J 43650 is properly installed, before removing the bushing, the end of the tool should be 116 mm (4.6 in) (a) from the block face.
If the J 43650 is less than approximately 114 mm (4.5 in) (a), recheck the tool alignment.




8. Tighten the nut on the J 43650 until the tension releases. When the tension releases, remove the J 43650 and the balance shaft bushing.
