Tools Required
J 43650 Balance Shaft Bearing Remover/Installer
Removal Procedure
- 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.
- 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.
- Install the J 43650
into the balance shaft hole. Insert the tool
with the foot parallel to the shaft.
- When the J 43650
is inserted into the block turn bearing tool so that the foot becomes perpendicular
to the shaft.
- Center the foot of the bearing tool on the balance shaft bushing.
- 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.
- 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.
- Tighten the nut on the bearing tool
until the tension releases. When the tension releases, remove the bearing tool and
the balance shaft bushings.
