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

  A:

  To service and repair the Crankshaft main bearing seal, first take out the transaxle and the Flywheel off. Make use of the Crankshaft rear oil seal remover (J 42841) in placing it on the Crankshaft and mark securing it with the retaining bolts. Use a variable speed drill motor with a socket adapter to install eight self-drilling screws one inch long into the seal through the guide holes in the removal tool, slow down on the drill because the screws start to be screwed into the seal. Once you have installed all eight screws, you will have to take out the retaining bolts and which will allow you to attach the center screw to the j42841 while drawing it in to take the seal assembly from the Crankshaft. Prior to installing the new Crankshaft rear oil seal, it is important to make sure the drain is clear of obstructions to avoid leaks. Clear any debris from the Crankshaft rear oil seal drain with wire or an unbound plastic tie wrap. It is to apply the clean engine oil (GM P/N 12345501 or an equal clean engine oil) to the outer diameter of the cylinder block Crankshaft rear oil seal part without any contamination of the green coat of the inner diameter. Wipe the out diameter of the Flywheel flange with a lint free cloth and lubricate the outer part of the new Crankshaft rear oil to a clean engine oil. Loosen the center bolt of the Crankshaft rear oil seal installer (J 42842) so that center hub extends approximately one half of an inch beyond the outer plate, then mount the j 42842 to the crank shaft and bolt the three mounting bolts into the crank shaft flange. Tighten the bolts to securely mount the j 42842 and then install the Crankshaft rear oil seal by tightening the center bolt until the j 42842 bottoms onto the crankcase. Loose the center bolt to relieve pressure, then loosen the three mounting bolts, and take off the j42842 from the Crankshaft flange. Check the installation depth around the circumference of Crankshaft rear oil seal and reinstall the j 42842 again repeating the installation procedures if necessary. Make sure the final to be reinstalled is the Flywheel and the transaxle.

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

  A:

  The beginning of crankshaft rear oil seal replacement requires Flywheel removal. Fit the crankshaft rear oil seal remover (J 42841) onto the crankshaft while using retaining bolts to secure it. The variable speed drill motor combined with the socket adapter allows you to install eight one-inch self-drilling screws into the seal using the guide holes of the removal tool while manually decreasing drills speed as screws thread into position. After installing all screws onto the j 42841, detach the retaining bolts to drive forward the screw controlling removal of the seal assembly from the crankshaft. You need to verify that the drain maintains complete clearness to stop any potential leaks when preparing to install the new crankshaft rear oil seal. Wipe out debris from the crankshaft rear oil seal drain using wire or an unbound plastic tie-wrap. Apply gm p/n 12345501 (Canadian P/N 992704) or equivalent clean engine oil to coat the outer cylinder block crankshaft rear oil seal area while making sure to not touch the green coating inside the new seal's inner diameter. Clean the outer diameter of the Flywheel flange with a lint-free cloth before applying clean engine oil to the new crankshaft rear oil seal's outer rubber surface. Use the crankshaft rear oil seal installer (J 42842) to loose its center bolt until the center edge reaches one-half inch beyond the outer plate before mounting it onto the crankshaft and threading three bolts onto the crankshaft flange. Tighten these bolts until the j 42842 sits securely. Insert the crankshaft rear oil seal through tightening the central bolt until the j 42842 touches the crankcase before easing tension by loosening the center bolt then unplugging the three mounting bolts. After removing the j 42842 from the crankshaft flange look at the depth of installation across the crankshaft rear oil seal's full circumference before redocking when needed. Finally, reinstall the Flywheel.
