Remove front and rear seal groups as follows:NOTE: Seals and wear sleeves can not be used again, after the seals and wear sleeve are separated,a. Use the 1U7600 Puller group to remove the seals.b. Use the 5P7318 Distorter Group to remove the wear sleeves.Install front and rear seal groups as follows:a. Clean the outer surface of the CRANKSHAFT with 4C9500 Quick Cure Primer.b. CRANKSHAFT seals must be installed with the lip of the seal toward the inside of the engine as shown. Make sure the correct seal is installed on eash end of the CRANKSHAFT. Use the 2W1733 Seal Group on the front and the 2W1734 Seal Group on the rear.
