AUTION:
Under no circumstances should the crankshaft setting peg 303-531 be used in the following
operations, to lock the crankshaft.
NOTE:
Should extra locking of the crankshaft be required, use a lever against one torque converter boss.
Remove the plastic mesh cover from the torque converter housing for access.
Install the crankshaft locking tool to the damper. 1. Install adaptor 303-191-03 to the main locking tool 303-191.
2. Reposition the crankshaft/damper to align the mounting holes and install the locking tool to the damper using the bolts provided with the tool.
3. Loosen, but do not remove the damper securing bolt from the crankshaft.
7. Remove the locking tool from the damper. Remove the damper securing bolt.

8.

NOTE:
The damper only needs to be withdrawn along the crankshaft nose by approximately 2mm before
removing the puller. The damper will then either be loose or only require a sharp tap with a mallet to
release it from the split locking ring.
Remove the damper from the crankshaft. 1. Install adaptor 303-191-02 to the damper extractor tool 303-588 (Use the socket head screws provided with the puller).
2. Locate the thrust button into the end of the crankshaft; the O-ring holds it in place.
 Assemble the puller to the damper.
 Extract the damper from the crankshaft.
9. Remove the puller components from the damper. Remove the thrust button from the end of the crankshaft.
10
. Remove the split locking ring from the damper.

1.
Locate the new oil seal into the timing cover.
1. Remove the transit ring from the oil seal.
2. Position the seal to the timing cover.
2.
Install the new oil seal to the timing cover.
1. Install oil seal replacer tool 303-542 to the oil seal.
2. Use the nut and bolt provided with the tool, to fully seat the seal to the timing cover. Only tighten the nut sufficiently to locate the seal and no more, or the timing cover could become distorted.
 Allow the tool to stay in position against the seal for at least five seconds.
 Remove the special tool from the seal.
3. If the damper is not to be installed immediately, the transit ring should be installed temporarily to the seal.
Installation

. Install the crankshaft damper.
Apply petroleum jelly to the damper bore and O-ring seal.
1. Install the damper onto the crankshaft.
2. Install the split locking ring onto the crankshaft, inside the centre bore of the damper. 3. Install, but do not tighten, a new damper securing bolt.
