DISCHARGE VALVE TRAVEL:
Discharge valve travel must equal 0.018 0.003 inch.
To obtain discharge valve travel proceed as follows:
a. Obtain result of P plus R minus T which equals
valve travel.
b. Use correct thickness valve stop shims (2, 3 and
4, figure 6-7) to limit valve travel to 0.018 .
0.003 inch.
INTAKE VALVE TRAVEL.
Intake valve travel must equal 0.010 0.002 inch.
To obtain intake valve travel proceed as follows:
a. dimension D with valve in place against valve
seat.
b. To dimension D add gaskets (11, figure 6-7) as
necessary to establish required intake valve
travel. Add gasket to surface F.
HEAD CLEARANCE:
Piston must be at dead center when establishing dimension B.
Head clearance as follows:
a. Obtain result of C minus B.
b. Subtract this dimension from intake valve travel.
c. Add all or part of shim (5, figure 6-6 to surface G to adjust result obtained in step b. to obtain proper head
clearance A.
d. Head clearance must equal 0.007 0.002 inch.
