NOTE:
Surfaces may be checked visually and
by feel for roughness, flaking, and
pitting of races and for scoring on the
outside of the bearing races. Shafts,
pins, etc., may be checked using vee
blocks and dial indicators.
NOTE:
Aluminum surfaces can withstand
considerable scratching and light
scoring without harming the engine
integrity or performance provided
these problems fall within the limits set
forth in the Fits and Clearances
section of this manual.
NOTE:
Fretting on the saddle supports in the
crankcase has a frosted appearance
and tiny pit holes. This usually
indicates a change in the size of the
bearing saddles that can be sufficient
to cause an excessively tight
crankshaft bearing fit.
