Timing Chain
Check for cracks and excessive wear at roller links. Replace
timing chain if necessary.
INSTALLATION
1. Install new oil seal to spacer.
2. Install spacer to fuel pump.
3. Install coupling to fuel pump of spacer.
Using the TORX wrench (special service tool), tighten the
sprocket nut to fix the coupling.
4. Install adjust shim.
For shim adjustment, measure dimension L [Distance
between front surface of coupling and the fuel pump flange
(spacer)] at two opposing points near the coupling bolt center.
Use the average of these two measurements to select the
shim grade that marked on adjust shim.
The shim adjustment is required only when the fuel pump is
replaced.

5. Before starting engine, bleed air from fuel piping. Refer to FL-18, "
Air Bleeding" .
INSPECTION AFTER INSTALLATION
Start engine and increase engine speed to check for fuel leak.
CAUTION:
Do not touch the engine immediately after stopped as engine becomes extremely hot.
NOTE:
Use mirrors for checking at points out of clear sight.

INSPECTION AFTER REMOVAL
Visual Check of Camshaft
Check the camshaft for one sided wear or scratches.
Replace the camshaft if there are abnormalities.
Camshaft Runout
Prepare V-block on a flat surface and secure camshaft journals
No. 2 and No. 5.
Set the dial gauge vertically on journal No. 3.
Rotate camshaft in one direction by hand, then read needle
movement on dial gauge. (Total indicator reading)
If it exceeds the limit, replace camshaft.
