DRIVESHAFT HOUSING
AND OIL PAN
Check the driveshaft and oil pan housings for dis-
tortion.
Place the housing
on
a surface plate. Use
a
dial indicator
to
check the flatness by measuring
the run-out
on
the top edge of the housing. The
maximum
allowable run-out
is
0.009
in
. (0.228
mm).
If you do not have access to a dial indicator and a
surface
plate, seek the services
of
a machine
shop.
DO NOT attempt to straighten a distorted
housing.
Replace
it.

IMPORTANT: A bent driveshaft or oil pan hous-
ing
will cause the upper driveshaft splines to wear
excessively and will also damage the crankshaft
splines. Additionally, a distorted upper oil pan
housing can
result
in
loss of oil or allow water to
enter the
oil.
