ASSEMBLY
FRONT PUMP MOUNTING
Install the pump mounting bracket on the front of the tractor with cap-screws and
lock-washers as shown in the parts section illustration. DO NOT tighten fasteners
at this time.
Slide the pump drive shaft into the crankshaft adapter. The end with the shorter
splines should be inserted into the adapter (if applicable).
Slide the splined drive shaft coupler onto the pump drive shaft. 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
tread locking agent. Tighten these bolts in succession, again checking for free
movement in the drive shaft. After all bolts are torqued, the end play on the drive
shaft 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 VAVLES ARE
OPEN! STARTING AT THIS TIME WILL CAUSE SERIOUS DAMAGE TO THE
PUMP.
GENERAL HOSE INSTALLATION
Refer to the parts section for detailed information about hoses and fittings for
this application.
When mounting the suction hose between the pump and the tank, the stainless
steel bands that are provided must be used. CAUTION: DO NOT use regular hose
clamps for this purpose.
For protection of hoses in contact with metal edges, wrap hoses with spit hose
sections and fasten with hose clamps or zip ties as needed.
