Select a feeler gauge for the correct valve lash

specification.

Valve Lash Specifications

Intake Exhaust

0.35 mm 0.68 mm

[0.014-inch] [0.027-inch]

Insert the feeler gauge between the top of the crosshead

and the rocker lever pad.

Two different methods for establishing valve lash clear-

ance are described below. Either method can be used;

however, the torque wrench method has proven to be the

most consistent.

• Torque Wrench Method: Use theinch pound torque

wrench, part No. 3376592, (normally used to set

preload on STC injectors), and tighten the adjusting

screw.

Torque Value: 0.6 to 0.7 N•m [5 to 6 in-lb]

• Feel Method: Tighten the adjusting screw until a

slight drag is felt on the feeler gauge.

Hold the adjusting screw in this position. The adjusting

screw must not turn when the lock nut is tightened.

Torque Values:

With torque wrench adapter, 54 N•m [40 ft-lb]

Part No. ST-669

Without adapter 68 N•m [50 ft-lb]

After tightening the lock nut to the correct torque value,

check to make sure the feeler gauge will slide backward

and forward between the crosshead and the rocker lever

with only a slight drag.
