Assembly Instructions:
__1. Apply a coat of white
lithium grease to the
inside of Main Bearing
#4 and slide it onto the
end of the crank shaft
assembly. Make sure
the dowel pin hole is
toward the end of the
crankshaft.
__2. Carefully set the crank
shaft assembly into
right case half. Make
sure dowel pin hole in
each bearing is aligned
with the dowel pins in
the case half, and the
crankshaft assembly is
fully seated in the case
half.
__3.

Temporarily mate the case halves and
rotate the crankshaft. Listen and "feel" for a knock
which may indicate the case is interfering with the con-
necting rods. If interference is detected:
a. Disassemble the case halves and identify the loca-
tion of the interference.
b. Remove crank assembly.
c. Taking care not to get grinding dust on other parts,
use a remove case material to provide at least .045"
clearance. Dremel-style motor tools work well for
this operation.
d. Reinstall the crankshaft assembly and repeat step 3
until all interference is eliminated.

crankshaft are still fully seated on the dowel pins in the
case half.
__5. Align the single dot on the gear of the cam shaft as-
sembly with the two dots on the gear of the crankshaft
assembly and rotate the cam down into the into the
cam bearings in the right case half. After seating the
camshaft in the bearing, make sure the dots still align as
shown in photo 5a.
