ASSEMBLY
Assembly Section 2-3
DRIVESHAFT AND FRONT PUMP MOUNTING
Install the pump mounting bracket on the front of the tractor with capscrews and washers as
shown in the Parts Section illustration. DO NOT tighten fasteners at this time.
Install the crankshaft adapter plate that is supplied with the coupler kit #06520634 first.
Secure the adapter to the crankshaft pulley using socket head capscrew #06530568 and washer
#06533014. Apply Loctite 271 to the threads of the capscrews, and torque to 76 ft-lbs.
Refer to
the assembly instructions supplied with the flex coupling assembly for securing the flex
coupling to the crankshaft adapter plate.
Slide the splined driveshaft coupler onto the pump driveshaft. Install the pump onto the
mounting bracket. NOTE: the shaft is offset to one direction, the pump should be installed with
the offset side on top. Install hardware for securing pump to the pump mount, DO NOT tighten.
Align pump so that splined coupling can be moved back and forth by hand. Tighten pump
mounting bolts in succession rechecking for spline coupling movement. Remove the pump
mounting bracket bolts one at a time and apply a thread locking agent. Tighten these bolts in
succession, again checking for free movement in the driveshaft. After all bolts are torqued, the
end play on the driveshaft should be 1/16” to 1/8”, and coupler should move freely with hand
pressure. If end play is less than 1/16”, grind the end of the shaft to achieve the proper end play.
If there is more than 1/4" of end play, return the shaft with specifications for a longer shaft.
CAUTION: DO NOT START THE TRACTOR UNTIL ALL HOSES ARE ATTACHED, TANK
IS FILLED WITH PROPER OIL AND BALL VALVES ARE OPEN! STARTING AT THIS TIME
WILL CAUSE SERIOUS DAMAGE TO THE PUMP.

ADJUSTING REAR WHEELS
Raise rear of tractor onto jack-stands. Follow the instructions in the tractor owner’s
manual for adjusting tires and rims . The back wheels MUST be adjusted to the widest
setting. NOTE: This may require switching the wheels to opposite sides of tractor. Also take
note of any width restrictions when transporting by trailer. (For ease of installation, it is best to
leave the rear wheels removed during installation of the mower.)
