  Q: How to Service and Repair the Crankshaft Seal on Cadillac DeVille?

  A:

  For servicing and repairing the Crankshaft main bearing seal, it is first necessary to take off the transaxle and the Flywheel. Use the Crankshaft rear oil seal remover (J42841) by positioning the tool over the Crankshaft and fasten it with the help of the retaining bolts. In slope or trenches, provide for the immediate replacement of the pipes by locating the new pipes in the same straight line and becon near the old pipes. At every slip joint install a region-up valve to offer easy disconnection and area example every ft. Provide suitable numbers of transition junctions in curve pipes along the line where request is demande. This allows the replacing pipes to have a built in deviation. When all screws are installed, take off the retaining bolts and hook up the center screw to the j42841, pulling the screw till the seal assembly gets detached from the Crankshaft. Make sure the drain is clear prior to installing the new Crankshaft rear oil seal to avoid leaks. Remove any debris from the Crankshaft rear oil seal drain using wire or an unbound plastic tie wrap and apply clean engine oil (GM P/N 12345501 or equivalent) on the outer diameter of the cylinder block Crankshaft rear oil seal area. Do not contaminate the green coating at the inner diameter of the Crankshaft rear oil seal. Clean the outer diameter of the Flywheel flange using a lint-free cloth and apply clean engine oil (GM P/N 12345501 or equivalent) on the outer side of the Crankshaft rear oil seal. Loosen the center bolt for the Crankshaft rear oil seal installer (J42842) until the center hub extends about one-half inch beyond the outer plate, and mount the j42842 atop the Crankshaft by threading the three mounting bolts into the Crankshaft flange and tighten until the j42842 is firmly attached. Replace the Crankshaft rear oil seal by tightening the center bolt as far as the j42842 bottoms on the crankcase, and then loosen the center bolt to relieve stress off the Crankshaft flange before removing the j42842. Examine the installation depth in the circumference of the crank shaft rear oil seal install, and if needed install the j42842 and rework the installation procedures. Finally, you ought to reinstall the Flywheel and transaxle.

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

  A:

  The replacement of the crankshaft rear oil seal starts with removing the Flywheel. You should employ the crankshaft rear oil seal remover (J 42841) by fitting it to the crankshaft then fastening it with retaining bolts. A variable speed drill combined with a socket adapter allows you to insert eight one-inch self-drilling screws into the seal through the guide holes of the removal tool while slowing the drill speed before complete insertion. After installing all screws, remove the retention bolts while tightening the central screw on the j 42841 until the seal assembly separates from the crankshaft. A leak-free installation of the new crankshaft rear oil seal requires you to confirm that the drainpipe is clear. Scrape out debris from the crankshaft rear oil seal drain using either wire or an unbound plastic tie-wrap. Apply gm p/n 12345501 engine oil (or equivalent Canadian P/N 992704) to the cylinder block's outer crankshaft rear oil seal region while ensuring the area stays free from contamination before seal installation onto the crankshaft. Apply clean engine oil gm p/n 12345501 (Canadian P/N 992704) or equivalent to both the outer rubber surface of the new crankshaft rear oil seal and a lint-free cloth used to wipe down the outer diameter of the Flywheel flange. Insert the crankshaft rear oil seal installer (J 42842) center bolt until its hub extends one-half inch beyond the outer plate. Then mount the j 42842 onto the crankshaft by screwing three mounting bolts into the crankshaft flange until the j 42842 provides strong mounting. Follow this sequence to set up the crankshaft rear oil seal: first, tighten the center bolt of the j 42842 to reach crankcase bottom-out then backtrack the center bolt before removing three mounting bolts. After removal of j 42842 from the crankshaft flange inspect installation depth across the entirety of the crankshaft rear oil seal's circumference then reinstall the Flywheel only if necessary inspections reveal incompatible installation depths.
