HEAD TORQUE CHECK
1.
Run engine until coolant outlet temperature is
higher than 170 °F (77 °C).
2.
Stop the engine and remove the cylinder head
cover.
3.
Check the torque of the cylinder head nuts and
capscrews in the correct sequence as shown in
Fig. 8.29. The correct torque is 100 lb-ft (136
N m) for 1/2" studs and capscrews; 60 lb-ft (84
N m) for 7/16" studs.
• If a nut or a capscrew turns when checked,
tighten it to the correct torque.
• If a nut or a capscrew does not turn when
checked, loosen it by 30 to 60° and then
tighten to correct torque.

8.10 STEM TIP TO ROCKER
ARM CLEARANCE
CHECK
The correct clearance between the top of the valve
stem and the rocker lever is 0.012" (0,30 mm) with
the engine cold.
NOTE: No. 1 cylinder is at the front of the engine.
To adjust this clearance:
1.
Turn the crankshaft in the normal direction of
rotation until the inlet valve of No. 4 cylinder
has just opened and the exhaust valve of the
same cylinder has not fully closed. Check the
clearances of No. 1 cylinder valves and adjust
if necessary, Fig. 8.30.
2.
With No. 2 cylinder valves set as given above
for No. 4 cylinder, check and adjust clearances
for No. 3 cylinder valves.
3.
With No. 1 cylinder valves set, check and
adjust clearances of No. 4 cylinder valves.
4.
With No. 3 cylinder set, check and adjust
