Firmly thrust the crankshaft rearward, and then forward. This will align the crankshaft rear bearing thrust surfaces. 12.2. With the crankshaft pushed forward, insert a feeler gauge between the crankshaft and the crankshaft rear bearing thrust surface to measure the clearance. Specification Crankshaft end play 0.05-0.20 mm (0.002-0.008 in) 13. Rotate the crankshaft in order to check for binding. A bent crankshaft or lack of proper crankshaft bearing clearance may cause binding. 14. If the crankshaft does not turn freely, loosen the crankshaft bearing cap bolts on 1 crankshaft bearing cap at a time in order to determine the location of the binding. A lack of proper crankshaft bearing clearance may be caused by the following: • Burrs on the crankshaft bearing cap • Foreign material between the crankshaft bearing and the engine block • Foreign material between the crankshaft bearing and the crankshaft bearing cap • Damaged crankshaft bearing • Improper size crankshaft bearing Crankshaft Rear Oil Seal and Housing Installation Tools Required J 35621-B Rear Main Seal Installer Notice: Refer to Fastener Notices in Cautions and Notices. 1.
