Start By:a. remove crankshaft pulley and vibration damper
Any time the crankshaft seal is removed from the wear sleeve, a new sleeve and seal must be installed as a set. If the old seal is put back on the sleeve, the seal will leak.
1. Make at least three holes in seal (1) with a hammer and a sharp punch.2. Use tool (A) to remove seal (1). 3. Install tool (C) in the front housing bore as shown.4. Install tool (A) between tool (B) and wear sleeve (2). Turn tool (A) until the edge of the tool makes a flat place (crease) in the wear sleeve. Do this several places around the wear sleeve until the sleeve can be removed from the end of the crankshaft by hand.Install Crankshaft Front Seal And Wear Sleeve
The crankshaft seal and wear sleeve come as a set and must not be separated from each other at any time. Carefully read Special Instruction, Form No. SMHS8508, that is included with each seal and wear sleeve before any handling of the seal group is made.
1. Use the following procedure to install the crankshaft front seal and wear sleeve:a. Clean and make a preparation of the wear sleeve inside diameter, and crankshaft outside diameter with 6V1541 Quick Cure Primer. Make an application of 9S3265 Retaining Compound to the crankshaft outside diameter before the wear sleeve is installed on the crankshaft Do not let any Quick Cure Primer or Retaining Compound get on the lip of the seal.b. Install locator (A) and bolts (B) on the crankshaftc. Seal (1) and wear sleeve (2) must be installed dry.
Make sure the seal is installed with the part number and the arrows showing crankshaft rotation toward the outside.
The front and rear seals and wear sleeves have different spiral grooves in the seal. Because of this type of design, the front seal group for an engine is different from the rear seal group. If a seal group is installed on the wrong end of the engine, oil can actually be taken out of the engine instead of moving the oil back into the engine.
d. Put wear sleeve (2) and seal (1) as a unit in position on locator (A). e. Put installer (C) in position on locator (A).f. Put clean engine oil on the face of nut (D) and its contact area on installer (C). Install nut (D) on locator (A).g. Tighten nut (D) until the inside surface of installer (C) comes in contact with locator (A).h. Remove the tooling from the crankshaftEnd By:a. install vibration damper and pulley
