J 43650 Balance Shaft Bearing Remover/Installer

### Removal Procedure

1. Remove the balance shaft bearing carrier bolts.

Important: It is possible to install the intake side balance shaft into the exhaust side and vice versa. Use care not to install the balance shafts into the wrong bores. Engine vibration will result.

Important: Do not remove the front balance shaft bearing bolt.

2. Remove the balance shaft assemblies.

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.

3. Install the J 43650 into the balance shaft hole. Insert the tool with the foot parallel to the shaft.
4. When the J 43650 is inserted into the block turn bearing tool so that the foot becomes perpendicular to the shaft.
5. Center the foot of the bearing tool on the balance shaft bushing.
6. Once the tool is centered on the balance shaft bushing, then insert the centering guide into the front balance shaft bore and tighten the nut snugly with an appropriate wrench.

Notice: Assure the special tool J43650 is properly installed. It the bearing removal is attempted and the tool is not positioned properly, block damage may result.

7. To assure the J 43650 is properly installed, measure from one end of the front side of the nut to the end of the threaded shaft. The measurement should be between 74-77 mm (2.91-3.03 in). If the measurement is less than 73 mm (2.87 in) the tool is not properly installed and should be re-installed.
8. Tighten the nut on the bearing tool until the tension releases. When the tension releases, remove the bearing tool and the balance shaft bushings.
