Install Machined Pump Mount Plate The machined pump mount plate (P/N 02979436) bolts to
the front of the bolster in the four existing threaded bolt holes (See Figure 22). These bolt holes will have
plastic plugs in them that will need to be removed (See Figure 14). The pump mount Plate (P/N
02979436 ) bolts to the tractor with 4 mounting bolts (Bolt P/N 02975692 -
50MM PL GR10.9 , Lockwasher P/N 02971158 - M20) tighten these four bolts down at this time (See
Figure 25).

has a 7/8" X 13 spline end and a 3/4" w/ 3/16" keyway end
(See Figure 23 & 23A). The 7/8" x 13 spline end goes
toward the engine and fits into the spline hub that was
bolted to the crankshaft (See Figure 13, 13A & 13B). Coat
the splined end of shaft with an anti-sieze compound
before inserting it into the splined hub.

and coat the keyed shaft end with a anti-seize compound
before installing coupler. Slide the coupler onto the
driveshaft with the 5/8" X 9 spline coupler outward toward
where the pump will mount. (See Figure 25).
