Rear Crankshaft Seal Installer J-44642
CRANKSHAFT SEAL INSTALLER
2001- Later GMT800, 2500HD, 3500 with 6.6 liter Duramax diesel engine
The rear seal is press fitted to both the engine block and crankshaft.
Fit of inner/outer seal bodies is critical and any misalignment can
result in leakage. J-44642 is a two-piece tool that mounts to the
crankshaft and forces on both inner and outer seal bodies. Place the
new seal on the inner body of J-44642. Attach the tool to the end of
the crankshaft assembly. Turn the forcing screw on the tool to press
the seal until it bottoms in the block.
