Select collar, P/N 341440, and th e co rrect shim
gauge bar:
• “M2”: Shim gauge bar, P/N 349957
• “L2”: Shim gauge bar, P/N 328367
Slide the collar onto the driveshaft with large e nd
in contact with the bearing housing.
Insert the assembled driveshaft into the tool base
and t ighten p reload screw against the driveshaf t
until groove on the sp ring-loaded plunger is flush
with end of thread s. Tighten locking ring on pre-
load screw.
Rotate the driveshaft se veral revolutio ns to seat
bearings.
Lay th e tool base on it s side. Position the shim
gauge bar against guide pins of the tool base.
Check squareness of the be aring housing mount-
ing surface by holding the shim gauge bar against
the pinion while rot ating just th e be aring ho us-
ing. Use a fe eler g auge to me asure cle arance
between the g auge b ar and th e bearing ho using
between each p air of screw hole s. Re place the
bearing housing a nd rep eat check if var iance is
greater than 0.004 in. (0.101 mm).
Check squareness of t he pinion to th e driveshaft.
Hold the shim ga uge b ar aga inst the bearing
housing (between the screw holes) wh ile rotating
just the drive shaft and pinio n assembly. Mea-
sure clear ance betwee n th e ga uge bar a nd th e
pinion a t several location s. If varian ce is grea ter
than 0.002 in. (0.0 50 mm) replace the pinion or
driveshaft, as necessary, and repeat check.
Subtract th e average clearance measureme nt
from 0.020 in . (0.508 mm) to determine the cor-
rect shim thickn ess requ ired. Select th e fewest
number of shims to achieve the correct thickness.
Remove the driveshaft from the tool and add the
required shims be tween the b earing housing an d
the thrust washer.
IMPORTANT: Use extreme care when removing
bearing housing to avoid damaging the seals. Use
Driveshaft Seal Protector, P/N 318674.
Check cleara nce a gain. The measureme nt
between the gaug e bar and pinion should be
0.020 in. (0.508 mm).
Remove th e nut and pinion from the driveshaf t.
Discard the nut.
