Installation Of Crankshaft Seals And Wear Sleeves 5.4″ (137) Bore, 6 Cylinder Engines

A Tools needed: 1-9S8870 Locator, 2-5P7294 Installer, 3-5P7295 Installer, 4-9S8876 Locator, 5-9S8858 Nut, 6-618718 Bolts (three), 7-2P2346 Bolts (three), 9S8889 Bolts (two – not shown).

B Install Rear Seal

1 For standard engines, fasten 9S8870 Locator (1) to the rear of the crankshaft with three 618718 Bolts (6). [Bolts (6) will go through locator (1) and gear (8), then into the crankshaft.] For engines that have a BrakeSaver, use three 2P2346 Bolts (9) to fasten locator (1) in position against sleeve (10). [On these engines the bolts will go through locator (1), BrakeSaver Rotor Assembly (11) and then into the crankshaft]. Put clean engine oil on the outside diameter (A) of gear (8) or on the outside diameter (B) of sleeve (10) on engines that have a BrakeSaver.

2 For engines that use a 9N3131 Seal (12) and 9N3134 Wear Sleeve (13), fasten 9S8870 Locator (1) to the rear of the crankshaft with three 618718 Bolts (6). [Bolts (6) will go through locator (1) and gear (8), then into the crankshaft]. Put clean engine oil on the seal lip of seal (12) and on the outside diameter of wear sleeve (13). Install seal (12) on wear sleeve (13) as shown. Use 8M8060 Quick Cure Primer to clean outside diameter (A) of gear (8) and inside diameter (C) of wear sleeve (13). Put 9S3265 Retaining Compound on outside diameter (A) of the gear and inside diameter (C) of the wear sleeve.

3 For engines that do not use the 9N3131 Seal and the 9N3134 Wear Sleeve, put clean engine oil on the seal lip of seal (14). Start seal (14) into baffle (15) on standard engines, or into the stator on engines with a BrakeSaver. Put 5P7294 Installer (2) and 9S8858 Nut (5) on locator (1). Put lubricant at location (D) [between the face of the washer on nut (5) and its contact area on installer (2)]. Tighten nut (5) until installer (2) is against locator (1). NOTE: Do not tighten nut (5) too tight or the case (body) of seal (14) will be damaged.

4 For engines that use the 9N3131 Seal and the 9N3134 Wear Sleeve, put wear sleeve (13) with seal (12) on locator (1). Put 5P7294 Installer (2) and 9S88858 Nut (5) on locator (1). Put lubricant at location (D) [between the face of the washer on nut (5) and its contact area on installer (2)]. Tighten nut (5) until installer (2) is against locator (1).

C Install Front Seal and Wear Sleeve

1 Fasten 9S8876 Locator (4) to the front of the crankshaft with two 9S8889 Bolts (14). Put clean engine oil on the seal lip of seal (15) and on the outside diameter of wear sleeve (16). Put seal (15) on wear sleeve (16) as shown. Use 8M8060 Quick Cure Primer to clean the outside surface (A) of the crankshaft and the inside diameter (B) of the wear sleeve.

2 Put the wear sleeve with seal in position on the crankshaft as shown. Put 5P7295 Installer (3) and 9S8858 Nut (5) on locator (4). Put lubricant at location (C) [between the face of the washer on nut (5) and its contact area on installer (3)]. Tighten nut (5) until the inside surface of installer (3) is against locator (4).
