read the wordsTHIS SIDE OUTon seal (Fig. 90).
Pilot tool should remain on crankshaft during instal-
lation of seal. Ensure that the lip of the seal is facing
towards the crankcase during installation.
CAUTION: If the seal is driven into the block past
flush, this may cause an oil leak.
(3) Drive the seal into the block using Special Tool
6926-2 and handle C-4171 (Fig. 91) until the tool bot-
toms out against the block (Fig. 92).
