If one bearing shell is less than
minimum thickness shown in
Table 3-5, replace both bear-
ing shells (upper and lower).
Using a micrometer and ball attachment
(19), measure thickness of lower and
upper connecting rod bearing shells at
point (A), 90 degrees from parting line.
e. Fitting Piston
NOT E
Fit new or used piston to
corresponding cylinder liner
and retain as matched set for
assembly in engine.
(1)
Using a micrometer, measure piston skirt
outside diameter (B) parallel to and
perpendicular with piston pin bore at
room temperature, 70°F (21°C). Skirt
diameter for model 5063-5299 is 3.8699
to 3.8721 inches. Skirt diameter for
models 5063-5395 and 5063-5398 is
3.8679 to 3.8701 inches. Taper and
out-of-round must not exceed 0.0005
