AUXILIARY PTO
Some models of the vertical shaft 110000 and
120000 engines were equipped with an auxiliary
PTO shaft. The auxiliary PTO shaft (E, Figure
23) extends through the side of the sump,
perpendicular to the crankshaft. Rotation can be
either clockwise or counterclockwise, as viewed
from the end of the shaft. The oil slinger (A),
camshaft (C), and worm gear (D) are pre-
assembled and must be serviced as a set.
NOTE: The clockwise system requires a thrust
washer (B) installed at the upper camshaft
journal. The counterclockwise system requires
the thrust washer be installed at the lower
journal, under the worm gear.

crankshaft, then remove sump.
2. To remove auxiliary PTO shaft from sump,

bottom of sump. The slinger, camshaft,
and worm gear assembly will remain in the
cylinder.
