ASSEMBLY
Assembly Section 2-5
DRIVESHAFT AND FRONT PUMP MOUNTING
Install driveshaft into the crankshaft adapter.
Slide splined driveshaft coupler onto the pump driveshaft. Install the pump onto the mounting
bracket. NOTE: the pump is offset to one direction and the pump should be installed with the
offset side on top. Install hardware for securing pump to the pump mount, DO NOT tighten.
Install pump and align so that splined coupling can be moved (FREE PLAY) back and forth
by hand. Rotate coupler and check free play every 1/4 turn. Tighten pump mounting bolts in
succession, rechecking for spline coupling free play. Remove the pump mounting bracket bolts
one at a time and apply a thread locking agent. Tighten these bolts in succession, again check-
ing for free play 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.

MAINFRAME INSTALLATION
With an overhead hoist and / or jack-stands, raise one side of the frame up to the correctly
matching mounting holes. Install capscrews and other hardware to secure the sides of the
mainframe to the tractor casting, as shown on the tractor mount kit page in the Parts Section.
DO NOT tighten at this time. Remove the capscrews one at a time and apply a thread locking
agent. Reinsert the capscrews and tighten / torque to values noted in the torque chart located in
the Maintenance Section of this manual.
