d discard the seal.
Unscrew the centre bol
t until
it is below the face of the
tool.
11. Clean all relevant components.

sure that the cent
re bolt is unscrewe d to below the face
which is to fit to the crankshaft and position the tool to the
crankshaft.
Chec k that
the nuts are fully unscrewed and enter the two
bolts to the crankshaft thre ads and lightly tighten.
4. Tight
en the nuts, finger tight, to hold the tool assembly against
the seal. Check that the seal and the tool are approximately
parallel to the rear of the engine.
5. Pres s th
e seal into the housing.
Ho
ld e
ach bolt stationary, in
turn, and tighten its nut a
small amount (approximately two to three flats) in turn, to
press the seal fully into the housing. until the tool is in
contact with the cylinder block.
6. Remove the tool from the crankshaft.
Chec k that
the seal is located correctly.
7. Fit the drive plate. Refer to Operation (SC) 12.53.13.
8. Install the transmission. Refer to Operation 44.20. 01 in
Section 307-01B.
9. Remove the paint protection sheets and close the engine
compartment cover.
