19. Fully lift up lever (A), and push the slack guide (B) into the inside
of chain tensioner (for oil pump) (1).

The slack guide is released by fully lifting the lever up. As the
result, the slack guide can be moved.
20. Matching the hole on lever with the hole on tensioner body,
insert a stopper pin (C) to secure slack guide.
NOTE:
Use approximately 1.0 mm (0.04 in) diameter. hard metal pin as
a stopper pin.
21. Remove chain tensioner (for oil pump).

When the holes on lever and tensioner body cannot be aligned, align these holes by slightly moving the
slack guide.
22. Hold the WAF part of oil pump shaft (A), and then loosen the oil pump sprocket bolt and remove them.
CAUTION:

Secure the oil pump shaft with the WAF part.

Never loosen the oil pump sprocket bolt by tightening the
oil pump drive chain.
23. Remove crankshaft sprocket, oil pump sprocket and oil pump drive chain as a set.
24. Remove timing chain tension guide (front cover side) from front cover if necessary.
INSPECTION AFTER REMOVAL
Timing Chain

Check timing chain and oil pump drive chain for cracks (A) and
any excessive wear (B) at the roller links of timing chain.

Replace timing chain and/or oil pump drive chain if necessary.

4. Hold the WAF part of oil pump shaft (A), and then tighten the oil
pump sprocket bolt.
CAUTION:

Secure the oil pump shaft with the WAF part.

Never loosen the oil pump sprocket bolt by tightening the
oil pump drive chain.
5. Install chain tensioner (for oil pump) (1).

Fix the plunger at the most compressed position using a stop-
per pin (A), and then install it.

Securely pull out ( ) the stopper pin after installing the chain
tensioner (for oil pump).

Check matching mark position of oil pump drive chain and
each sprocket again.
6. Align the matching marks of each sprocket with the matching
marks of timing chain.
NOTE:
*: There are 2 outer grooves in camshaft sprocket (INT). The
wider one is a matching mark.

If these matching marks are not aligned, rotate the camshaft
slightly by holding the hexagonal portion to correct the posi-
tion.
CAUTION:
Check matching mark position of each sprocket and timing
chain again after installing the timing chain.
