HOSE-RADIATOR 1765330 - Caterpillar

Start By:a. remove damper guard 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. Remove the bolts from adapter (1). Install two 5/16" -13 NC forcing screws in the adapter to remove it from the drive 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 several places around the wear sleeve until the sleeve can be removed from the end of the crankshaft by hand.Install Crankshaft Front Seal & Wear Sleeve
Any time the crankshaft 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 leak. 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 must be used.
The front seal and wear sleeve cannot be exchanged with the rear seal and wear sleeve. There are grooves in the sealing lip of the seals that direct the oil back into the crankcase as the crankcase turns. An exchange of front and rear seals would pump the oil 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 as shown. Install the O-ring seal on adapter (1). 3. Install tool (B) over the studs of tooling (A). Install the 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 no put engine oil on the seal during installation. Lubrication of the seal at installation can be a false indication of leakage at a later time.5. Clean the outer surface of the crankshaft with 6V1541 Quick Cure Primer. Put 9S3265 Retaining Compound on the outside diameter of the crankshaft and the inside diameter of the wear sleeve.6. Put clean engine oil on the adapter O-ring seal.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 against the shoulder on tool (F).10. Install tooling (B) and (F) as a unit on the guide bolts and over the locator.11. Put clean Multi-purpose Grease on the face of nut (G). Install nut (G) on the locator. Tighten nut (G)
