four locations.

2.

Set dial indicator (A) vertically to No. 3 journal.

3.

Turn camshaft to one direction with hands, and measure the
camshaft runout on dial indicator. (Total indicator reading)

Inspection and Adjustment

INFOID:0000000010282055

INSPECTION

1.

Place the valves of the cylinder concerned at the “end of
exhaust - beginning of intake” position and inspect the clearance
(X). 
NOTE:
Dimension (Y) corresponds to the tappet thickness sizes (there
are 25 sizes at the service parts). 

2.

Compare the values recorded with the values specified, then
replace the tappets which are not within tolerance.

ADJUSTMENT

1.

The camshaft must be removed to replace the tappets.
Determining dimension (Y).

2.

Set up the following assembly using dial gauge stand
