How to replace the rear crankshaft seal on Chevrolet Express 1500?

You should begin by removing the engine Flywheel and follow it up by removing the crankshaft rear oil seal from the rear cover. Check that you remove any Flywheel spacer before continuing while skipping oil lubrication on both the inside diameter of the oil seal and crankshaft surface because the original crankshaft rear oil seal needs replacement. Apply clean engine oil to the outside diameter (OD) of the oil seal but keep the seal surface free from oil and other lubricants. After liberally applying clean engine oil at the rear cover oil seal bore you must ensure that the crankshaft surface remains free of oil. Install j41479 tapered cone and bolts to the crankshaft rear where you should tighten each bolt equally until they are just tight enough. The tapered cone guides the rear oil seal as you push this component into the rear cover bore. It is necessary to thread the j41479 threaded rod through the tapered cone so the tool comes into contact with the oil seal prior to sealing it into position. Twist the tool's handle toward yourself while inserting the seal into the cover bore until the seal reaches its bottom position. You should remove the j41479 and reattach the engine Flywheel as the final step.
