TIMING CHAIN
CAUTION:
Never overtighten slack guide mounting bolt (2). It is nor-
mal for a gap (A) to exist under the bolt seat when mounting
bolt is tightened to specification.
7. Install the timing chain tensioner (primary) with the following procedure:
a. Pull plunger stopper tab (A) up (or turn lever downward) so as to
remove plunger stopper tab from the ratchet of plunger (D).
NOTE:
Plunger stopper tab and lever (C) are synchronized.
b. Push plunger into the inside of tensioner body.
c. Hold plunger in the fully compressed position by engaging
plunger stopper tab with the tip of ratchet.
d. To secure lever, insert stopper pin (E) through hole of lever into
tensioner body hole (B).
 The lever parts and the tab are synchronized. Therefore, the
plunger will be secured under this condition.
NOTE:
Figure shows the example of 1.2 mm (0.047 in) diameter thin screwdriver being used as the stopper pin.
e. Install timing chain tensioner (primary) (1).
 Remove any dirt and foreign materials completely from the
back and the mounting surfaces of timing chain tensioner (pri-
mary).
f. Pull out stopper pin (A) after installing, and then release plunger.
8. Check again that the mating marks on each sprocket and each timing chain have not slipped out of align-
ment.
9. Install new O-rings (1) on rear timing chain case.
10. Install new front oil seal on front timing chain case.
 Apply new engine oil to both oil seal lip and dust seal lip.

angle mark (B) on crankshaft pulley bolt (2). Tighten the bolt 90
degrees (angle tightening).
15. Rotate crankshaft pulley in normal direction (clockwise when viewed from engine front) to confirm it turns
smoothly.
16. Install in the reverse order of removal after this step.
