• Holding the crankshaft pulley bolt, lock the crankshaft to
remove the drive plate bolts.
• Remove drive plate bolts diagonally.
CAUTION:
• Do not damage the drive plate. Especially, avoid deform- ing and damaging the signal plate teeth (circumference
position).
• Keep magnetic materials away from signal plate.
• Place the drive plate with th e signal plate surface facing
upward.
4. Remove the rear oil seal using suitable tool. CAUTION:
Do not damage crankshaft or oil seal retainer surface.
INSTALLATION
1. Apply new engine oil to both the oil seal lip and dust seal lip of the new rear oil seal.
2. Install the rear oil seal.
• Install the rear oil seal so that each seal lip is oriented asshown.
• Press-fit the rear oil seal using suitable tool. CAUTION:
• Do not damage the crankshaft or cylinder block.
• Press-fit the oil seal straight to avoid causing burrs or
tilting.
• Do not touch grease applied onto the oil seal lip.
• Do not damage or scratch the outer circumference of
the rear oil seal.
• Tap until flattened with the front edge of the oil seal retainer.
3. Installation of the remaining components is in the reverse order of removal. Refer to EM-83, "
Disassembly
and Assembly", TM-186, "Removal and Installation (2WD)", TM-188, "Removal and Installation (4WD)".
CAUTION:
• When replacing an engine or transmission you must make sure the dowels are installed cor-
rectly during re-assembly.
• Improper alignment caused by missing dowels may cause vibration, oil leaks or breakage of
drivetrain components.

WARNING:
• Situate vehicle on a flat and solid surface.
• Place chocks at front and back of rear wheels.
• For engines not equipped with engine slingers, attach proper slingers and bolts described in PARTS
CATALOG.
CAUTION:
• Always be careful to work safely, avoid forceful or uninstructed operations.
• Do not start working until exh aust system and engine coolant are cooled sufficiently.
• If items or work required are no t covered by the engine section, follow the applicable procedures.
• Always use the support poin t specified for lifting.
• Use either 2-point lift type or separate type lift. If board-on type is used for unavoidable reasons, support at the rear axle jacking point with transmission jack or similar tool before starting work, in
preparation for the backward shift of center of gravity.
• For supporting points for lifting and jacking point at rear axle, refer to GI-30, "
Garage Jack and
Safety Stand".
