Start By:a. remove flywheel Any time the crankshaft seal is removed from the wear sleeve, a new sleeve and seal must be installed as a unit. If the old seal is put back on the sleeve, the seal will be damaged. 1. Remove the bolts from adapter (1). Install two 5/16" -18 NC forcing screws in the adapter to remove it from flywheel housing. 2. Remove O-ring seal (3) and crankshaft seal (2) from adapter (1). 3. Install tool (B) in the adapter bore.4. Install tool (A) between tool (B) and wear sleeve (4). Turn tool (A) until the edge of the tool makes a flat place (crease) in the wear sleeve. Do this in several places around the wear sleeve until the wear sleeve can be removed from the end of the crankshaft by hand.Install Crankshaft Rear Seal & Wear Sleeve
Any time the crankshaft is seal is removed from the wear sleeve, a new sleeve and seal must be installed as a unit. If the seal is put back on the sleeve, the seal will be damaged.
1. Install adapter (1) on tooling (A).
If the crankshaft seal and wear sleeve come apart during installation, the seal and sleeve become scrap. A new seal and sleeve as a unit must be used.
The rear seal and wear sleeve can not be exchanged with the front seal and wear sleeve. There are grooves in the sealing lip of the seals that direct the oil back into the crankcase as the crankshaft turns. An exchange of front and rear seals can cause the oil to come out of the crankcase.2. Install crankcase seal (2) and wear sleeve (4) as a unit on adapter (1). Make sure the lip of the seal is up. Make sure the lip of the seal is up. Install the O-ring seal on adapter (1). 3. Install tool (B) over the studs of tooling (A). Install nuts (C), and tighten the nuts evenly until the seal is seated against the bottom of the adapter bore.4. Remove nuts (C), tool (B) and tooling (A).
Do not put engine oil on the seal during installation. Lubrication of the seal at installation can give a false indication of leakage at a later time.
5. Clean the outer surface of the crankshaft with 6V1541 Quick Cure Primer.6. Put clean engine oil on the O-ring seal. Install the seal on the adapter and put 9S3265 Retaining Compound on the outside diameter of the crankshaft and the inside diameter of the crankshaft and the inside diameter of the wear sleeve. 7. Install tooling (D) on the end of the crankshaft.8. Install guide bolts (E) in the drive housing. Install adapter (1) on guide bolts (E) and over tooling (D). Make sure the wear sleeve makes contact with the end of the crankshaft. 9. Install tool (B) over the small outside diameter of tool (F) until tool (B) is seated against the shoulder on tool (F).10. Install tooling (B) and (F) as a unit on the guide
