AXIAL FLOAT ADJUSTMENT, REF. #1A3 or 3A3 —
Refer to Figure 24 and adjust float as follows:
Set up a dial indicator for determining axial movement of
the input shaft Ref. #1A3 or 3A3. Lift upward with a
twisting motion to obtain a reading.
WARNING:
Cover keyway with tape to avoid lacerations
to the hand.
Subtract from this reading the axial float for shaft, Ref.
#1A3 or 3A3, found in Table 15. This indicates the
thickness of shim(s), Ref. #31 for Sizes 4407 - 4507 and
Ref. #39 for Size 4608, to be removed. When removing
the shim(s), retain the .015" (0,38 mm) thick shim against
the housing, Ref. #10. Retighten fasteners and recheck
float. Readjust shimming, if necessary, until proper float is
achieved (Table 15).

removing a seal cage to install a seal, be sure to
replace the same shim-gaskets as removed to assure
correct bearing adjustments.
