Information:
Start By:a. remove vibration damper and pulley 1. Use a punch or Tool (A) to put a hole in seal (1). Use Tool (A) to remove seal (1) from the timing gear cover. When a replacement of the front seal is made, a replacement of the wear sleeve is to be made also. 2. Put Tool (B) in position in the seal bore as shown.3. Install Tool (C) between Tool (B) and the wear sleeve. Turn Tool (C) until the edge of the tool makes a flat place (crease) in the wear sleeve. Do this in two or more places until the wear sleeve is loose.4. Remove Tool (B) and the wear sleeve by hand.Install Crankshaft Front Seal & Wear Sleeve
The wear sleeve and seal must be installed at the same time.1. Install the crankshaft front seal and wear sleeve with Tool (A) as follows: a. Clean and make a preparation of the wear sleeve inside diameter and crankshaft outside diameter with 6V-1541 Quick Cure Primer. Make an application of 9S-3265 Retaining Compound to crankshaft outside diameter and wear sleeve inside diameter before the wear sleeve is installed on the crankshaft.b. Install locator (1) and the bolts on the front of the crankshaft.c. The wear sleeve and seal come as a set with the seal already installed on the wear sleeve. Make sure the lip of the seal is toward the inside of the engine as shown and the outside diameter bevel of the wear sleeve is toward the outside of the engine.d. Put the wear sleeve and seal in position on locator (1). e. Put installer (2) in position on locator (1).f. Put clean engine oil on the face of nut (3) and its contact area on installer (2). Install nut (3) on stud of locator (1).g. Tighten nut (3) until the inside surface of installer (2) comes in contact with locator (1).h. Remove Tool (A) and check the wear sleeve and seal for correct installation.End By:a. install vibration damper and pulley
