How to replace the Rear Crankshaft Seal on 4.8L, 5.3L, and 6.0L engines on Chevrolet Silverado 3500 Classic?

Remove the engine Flywheel and the crankshaft rear oil seal (141) from the rear housing using the crankshaft rear oil seal installer (J 41479) to replace the crankshaft rear oil seal on engines of 4.8l, 5.3l, and 6.0l. Before installation it is necessary to make sure that the Flywheel spacer should be removed if needed and avoid lubricating the inside diameter (ID) of oil seal or crankshaft surface. Always use the new oil seal and note that the new type is a reverse lip style seal that has the shape this side out in order to orient it correctly. Apply clean engine oil to the outside diameter (OD) of the oil seal and the rear housing oil seal bore. Mount the tapered cone and bolts to the back of the crankshaft, securing them in place without overtightening the bolts. Align the rear oil seal on the tapered cone with the this side out facing away from the engine, and then drive the j 41479 threaded rod into the tapered cone up to where it strikes the oil seal. Foresight the oil seal into the tool and rotate the handle of the tool clockwise until the oil seal is tucked upto the rear cover and bottoms in the cover bore. Finally, take out the j 41479 and reintroduce the engine Flywheel.
