17. Check cam gear end play through tappet bores in right

crankcase, for each cam gear as follows:

Turn engine over until lobe of cam gear being checked
is pointing toward its respective tappet guide hole.

Using a flat blade screwdriver, gently pry cam gear
toward gearcase cover.

Using a feeler gauge, measure gap between bore (in
crankcase) and cam gear shaft thrust face (shoulder).
This is cam gear end play.

Compare your cam gear end play measurements with
the

3.2 SPECIFICATIONS

. Make repairs as required

if end gap is less than the minimum specified, or
greater than the maximum specified (Service Wear
Limits).

TAPPETS

See

Figure 3-103

. Rotate engine so that both tappets (3)

from the cylinder being serviced will be installed on the
base circle (lowest position) of the cam.

Apply a liberal amount of engine oil to tappet assembly
(especially roller needles) for smooth initial operation.

Insert both tappets (intake and exhaust) into anti-rotation
device (2) with flats at upper end of each tappet positioned
so they will be facing front and rear when assembly is
installed in engine, and the tappet oil feed hole is facing
toward the gear cover.

Install anti-rotation device with tappets into bore in right
crankcase (4). Secure with screw (1). Tighten to 80-110
in-lbs (9.0-12.4 Nm).

VALVE TAPPETS

GENERAL

See

Figure 3-104

. The tappet assembly consists of tappet and

roller. The tappet and roller, under compression force from
valve spring, follow the surface of the revolving cam. The up-
and-down motion produced is transmitted to the valve by the
push rod and rocker arm. The tappet contains a piston (or
plunger) and cylinder; it also contains a check valve, which
allows the unit to fill with engine oil, thereby reducing clearance
in the valve train.

When a tappet is functioning properly, the assembly operates
with minimal tappet clearance. The unit automatically com-
pensates for heat expansion to maintain a no-clearance condi-
tion.

It is normal for tappets to click when engine is started after
standing for some time. Tappets have a definite leakdown rate
which permits the oil in the tappets to escape. This is necessary
to allow units to compensate for various expansion conditions
of parts and still maintain correct clearance operation. Tappets
are functioning properly if they become quiet after a few
minutes of engine operation.

CLEANING AND INSPECTION

Compressed air can pierce the skin and flying debris from
compressed air could cause serious eye injury. Wear
safety glasses when working with compressed air. Never
use your hand to check for air leaks or to determine air
flow rates. (00061a)

Clean all parts, except roller/tappet assembly, thoroughly
in solvent. Blow dry with compressed air.

Refer to

Table 3-29

. Inspect valve tappets for excessive

clearance in guide. Accurately measure tappet bore inner
diameter with a gauge. Excessive tappet guide clearance
is corrected by fitting a new tappet and/or replacing
crankcases.

NOTE

Inside and outside micrometers used for measuring tappets
and tappet guides must be calibrated to ensure accurate
readings.

Check tappet roller free play. Recommended service
practice is tappet replacement.

Check tappet roller end clearance.

Tappets should be soaked in clean engine oil and kept
covered until assembly.
