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 exhaust system and engine coolant are cool enough.
●If items or work required are not covered by the engine main body section, refer to the applicable
sections.
●Always use the support point specified for lifting.
●Use either 2-pole lift type or separate type lift as best you can. 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-35, "Garage Jack and
Safety Stand" .

CAUTION:
Be careful not to damage contact surface for the clutch disc
of the flywheel.
NOTE:
The flywheels, two block construction, allows movement in
response to transmission side pressure, or when twisted in its
rotational direction. Therefore, some amount of noise is normal.

12. Remove front chain case.
●Loosen fixing bolts in the reverse order of that shown in the
figure and remove them.
●Remove No. 6, 10 and 11 bolts with the rubber washer as
space is limited for pulling them out.
CAUTION:
●While front chain case is removed, cover openings to
prevent entry of foreign material into engine.

ley.
●When installing, color coded links on the secondary tim-
ing chain can be used as alignment marks. Marking may
not be necessary for removal; however, make alignment
marks as required because the alignment mark on fuel
supply pump sprocket may not be easy to see.
14. Remove chain tensioner.
a. Push the plunger of chain tensioner and keep it pressed with a
push pin.
