NOTE: To determine shell thickness proceed
as follows:
1. Add the diametral clearance to the crankshaft
diameter.
2. Subtract the total from the block bore diameter.
3. Divide the answer by two to determine the thick
ness of the bearing shell.

CRANKSHAFT END PLAY - PAGE 3-17
(6 CYLINDER)
After installation of new bearing shells, check
crankshaft end play which should be
.003 minimum to .009 maximum.
To check the amount of end play, measure the space
between the end of the No. 3 main bearing and the
adjacent side of the crankshaft. To check this accu-
rately, mount dial indicator KMO-30 on the base of
the crankcase. Set plunger of indicator against a
vertical surface of the crankshaft counterweight.
(Dial should be set at zero marking). End play can
now be checked by prying crankshaft back and forth
and note reading of indicator.
NOTE: The thrust face bearing width of the
number 3 crankshaft bearing has been increased
3/16" to distribute the thrust over a greater area
and improve the life of the bearing. Always use
"Genuine Hudson Bearings". Refer to your parts
manual for part numbers for this new type bear-
ing.
