Pinion Removal
1.
If a pilot web is used, remove the web cap screws.
a.
For S190 disassembly, install a M10 x 1.50 bolt
in the threaded jack holes found in-between the
pilot web cap screws.
b.
For S190 disassembly, use the pry slots pro-
vided at each end of the pilot web.
2.
Before the pinion nut can be loosened, you must de-
stake the nut from the slot of the pinion.
3.
To de-stake the nut, use a chisel or drift with a round
tip. The flange of the nut must be pushed far enough
outward so that the staked area will not interfere with
the pinion threads when the nut is removed. See dia-
gram below.
Failure to de-stake the pinion nut will result in damage to
the drive pinion threads when removed. The pinion nut
should never be reused, always replace with new.
4.
Remove the pinion nut.
