6-10. CRANKSHAFT REAR OIL SEAL AND WEAR SLEEVE (cont)
b. Installation (cont).
CAUTION
A new seal must be installed with a new wear sleeve. The seal should not be positioned in a wear groove on
wear sleeve. Positioning a seal on a worn, dirty, rough or grooved crankshaft surface will cause seal to leak.
(4) Using oil seal driver, install seal (7) with rubber lip facing outward. Drive seal in flush with machined surface of
seal plate (3).
(5) Be sure wear sleeve (6) on which seal (7) rides is free of dirt, nicks, burrs and wear grooves.
(6) Lubricate crankshaft flange with clean engine oil (OE/HDO). Apply a bead of sealant to the junction of cylinder
block, seal plate (3) and oil pan.
(7) Install seal plate gasket (9) and seal plate (3) on crankcase. Use extreme care when installing seal plate so the
oil pan gasket is not damaged. If oil pan gasket is damaged, remove oil pan and replace gasket.
(8) Install washers (2) and capscrews (1) to secure seal plate (3). Torque capscrews to 17 Ib-ft (23 Nm) (wet).
Tighten oil pan screws (4) to a torque of 8.3 Ib-ft (11 Nm) (wet).
(9) Check crankshaft-to-seal runout as follows:
(a) Load crankshaft so that all end play is taken up.
(b) Mount a dial indicator on face of crankshaft flywheel mounting flange.
