How to replace the rear crankshaft seal on Chevrolet Express 3500?

The crankshaft rear oil seal replacement process requires the engine Flywheel removal followed by removal of the crankshaft rear oil seal from the rear cover. The installation of the new oil seal requires removal of a Flywheel spacer (if applicable) and avoidance of coating the inside diameter of the oil seal or the crankshaft surface since the original crankshaft rear oil seal should not be used. Use new engine oil to lubricate the outside diameter (OD) of the new oil seal as well as the rear cover oil seal bore but make sure to stay clear of the crankshaft surface area. Position the j 41479 tapered cone and bolts at the crankshaft rear before tightening the bolts just to the point of snugging but no further. Insert the rear cover oil seal onto the tapered cone while directing it to enter the rear cover bore. Use the tapered cone of j 41479 until the tool reaches the oil seal then align the oil seal inside the tool. You should turn the handle of the tool clockwise until the seal reaches and stops at the rear cover bore. In the last step, install the engine Flywheel after taking out the j 41479 tool.

How to service and repair the front crankshaft seal on Chevrolet Express 3500?

Service of the front crankshaft seal requires removing the crankshaft balancer as a first step. First remove the crankshaft front oil seal by using a proper prying tool and then check for damage in the engine front cover seal bore and the crankshaft balancer sealing surface. The Cover Aligner Seal Installer (J 35468) requires an intact pre-applied grease on the crankshaft front oil seal prior to installation. Step up by checking that the crankshaft front seal has a flush and square arrangement with the engine front cover before reinstalling the crankshaft balancer.
