• Q: How to replace the rear crankshaft seal on 2005 Cadillac DeVille?

  A: Successfully replacing the crankshaft rear oil seal demands two essential tools: the repair requires using two tools: rear oil seal remover (J 42841) and crankshaft rear oil seal installer (J 45930). Rear oil seal remover (J 42841) and crankshaft rear oil seal installer (J 45930). Begin by removing the Flywheel. Position the j 42841 tool onto the crankshaft then bolt it in place. A drill motor with adjustable speed should be used with a socket adapter to install eight 25 mm (1.0 inch) self-drilling screws through the guide holes in the removal tool into the seal while the drill speed should decrease when the screws thread into place. The removal of retaining bolts allows the installation of a center forcing screw which pulls the seal assembly from the crankshaft when tightened. Verification of clear drain passage comes first so leaks can be avoided alongside debris removal through wire or an unbound plastic tie-wrap. A 5mm layer of gasket maker, gm p/n 1052942 (Canadian P/N 10953466) should be applied to the crankcase split line followed by coating the cylinder block crankshaft rear oil seal area with clean engine oil gm p/n 12345501 (Canadian P/N 992704). Protect the green coating inside the new crankshaft rear oil seal from contamination while you also clean the Flywheel flange. Clean engine oil gm p/n 12345501 (Canadian P/N 992704) should be used to lubricate the outer rubber surface of the seal. Apply clean engine oil gm p/n 12345501 (Canadian P/N 992704) to the cylinder block crankshaft rear oil seal area before using the j 45930 to measure the appropriate center hub protrusion beyond the outer plate at 13 mm (0.5 inch). Install the j 45930 with the two mounting bolts into the crankshaft flange. Tighten both bolts until the installer is firmly mounted. Tighten the j 45930 center bolt until it reaches the crankcase bottom before releasing pressure and unbolt the two mounting bolts. The j 45930 must be unwrapped from the crankshaft flange followed by an inspection of seal installation depth. Repeat the installation as needed, then reinstall the Flywheel.
