DISASSEMBLY
1. Remove engine, transaxle and transfer assembly from the vehicle, then separate engine and transaxle
and transfer assembly. Refer to EM-208, "
ENGINE ASSEMBLY" .
2. Remove clutch cover and disk. Refer to CL-14, "
CLUTCH DISC,
CLUTCH COVER AND FLYWHEEL" .
3. If they need to be replaced, replace pilot bush.

Using the pilot bushing puller (special service tool), remove
the pilot bush from rear end of crankshaft.
4. Install engine to engine stand as follows.
a. Remove flywheel.
b. Secure ring gear with the ring gear stopper (special service
tool), then loosen mounting bolts with TORX socket (size: T55,
Commercial Service Tools) and remove them. As an alternative
method hold crankshaft pulley with the pulley holder (special
service tool: KV10109300) to remove flywheel.
CAUTION:

Do not disassemble flywheel.

Do not place flywheel with signal plate facing down.

When handling signal plate, take care not to damage or
scratch it.

Handle signal plate in a manner that prevents it from
becoming magnetized.
c. Install the engine sub-attachment (special service tool) to the
rear side of cylinder block.

Align knock pins on cylinder block with pin holes on attach-
ment to install.
NOTE:
Installation bolts are part of engine sub-attachment.
d. Install the engine stand shaft (special service tool).
NOTE:
Use commercially available M12 (0.47 in) mounting bolts and
nuts (4 sets) with strength grade of 9T (minimum).
