Kent-Moore J-41479-B GM Rear Oil Seal Installer

This OEM tool is made of plastic. If you'd prefer a heavy duty all-steel tool, see ST-197.

5.7L Y CAR The rear seal on the LSI engine has two inner sealing lips. One is made of ribbed Teflon and is fragile. If installed without using J 41479, the lip will roll causing an oil leak

If you have the following seal/rear housing part numbers 12639250 or 89060436 you need the following: J-41479-B or ST-197.

If you have the following seal/rear housing part numbers 14088556, 14088557 or 10088158 you need the following: J-35621-B or ST-192.

Applications: 4.8L, 5.3L, 5.7L, 6.0L, 6.2L and more

If you're working on 1986 - 1996 you'll need J-35621-B instead.

Supercharged 6.2L V8s will have a 9-bolt rear crankshaft flange due to their performance output. Previous tool J-41479 will not fit 9-bolt crankshafts. J-41479-B will back-service to 1997. Unapproved installation methods may damage or incorrectly install the seal, resulting in leaks.

Manufacturer: SPX/Bosch (OTC Rotunda Kent-Moore Miller)
