PISTON PIN AND PISTON-PIN BORE
1. Measure the piston pin diameter in several
places. If any measurement varies by more
than 0.02 mm (0.001 in.), the piston pin and
bearing must be replaced as a set.

2. Insert a snap gauge into each piston-pin
bore; then remove the gauge and measure
it with a micrometer. Diameter must be
within specifications . Take two
measurements to ensure accuracy.

CRANKSHAFT RUNOUT
1. Using a set of V-blocks, support the
crankshaft on a surface plate.
NOTE: The V·blocks should support the
crankshaft on the outer bearings.
"
2. Mount a dial indicator and base on the sur-
face plate. Position the indicator contact
point against the crankshaft distance A
(PTO end) from the crankshaft
counterweight. Zero the indicator and
rotate the crankshaft slowly. Note the
amount of crankshaft runout (total in-
dicator reading).
3. Position the indicator contact point
against the crankshaft distance B (MAG
end) from the crankshaft counterweight.
Zero the indicator and rotate the
crankshaft slowly. Note
the amount
of
crankshaft runout (total indicator
reading)-
