Connecting Rods
If necessary, clean connecting rod surfaces as fol-
lows:
S Attach end caps to connecting rods. Following
these directions, tighten rod cap attaching bolts to
specifications. Recheck alignment. Refer to
4A-32.
Crocus cloth MUST BE USED to clean bearing
surface at crankshaft end of connecting rod. DO
NOT use any other type of abrasive cloth.
CAUTION
S Clean crankshaft end of connecting rod by using
crocus cloth placed in a slotted 3/8 in. (9.5mm) di-
ameter shaft, as shown. Insert shaft in a drill press
and operate press at full speed while keeping con-
necting rod at a 90_ angle to slotted shaft.
IMPORTANT: Clean connecting rod just enough to
clean bearing surfaces. DO NOT continue to clean
after marks are removed from bearing surfaces.
S Clean piston pin end of connecting rod, using
same method as above. Use 320 grit carborun-
dum cloth instead of crocus cloth.
S Thoroughly wash connecting rods to remove abra-
sive grit. Recheck bearing surfaces of connecting
rods. Replace any connecting rod that cannot be
properly polished. Lubricate bearing surfaces of
connecting rods which will be reused with 2 cycle
engine oil to prevent rust.
