Pinion Removal
1. For D170 assembly, remove the pinion cover. Use a
flat chisel to remove the cover from the carrier.
2. If a pilot web is used, remove the web capscrews.
a. For D190 disassembly, install a M10 x 1.5
bolt in the threaded jack holes found in-between
the pilot web capscrews.
b. For S190 disassembly, use the pry slots pro-
vided at each end of the pilot web.
3. Before the pinion nut can be loosened, you must de-
stake the nut from the slot of the pinion.
4. 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 on next page.
