ASSEMBLY
MAIN FRAME MOUNTING
Raise front of tractor as needed and slide the main frame under tractor from right
hand side. With an overhead hoist and / or jack-stands, raise the frame up to the
correctly matching mounting holes. Install cap-screws and all other hardware as
shown in main frame parts section. Remove the cap-screws one at a time and
apply a thread locking agent, then reinsert the cap-screws and tighten / torque to
values noted in the torque chart located in the maintenance section of this manual.
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.
Thread the pump drive shaft into the crankshaft adapter.
Slide the splined drive shaft coupler onto the pump drive shaft. Install the pump
onto the mounting bracket. NOTE: the pump 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.
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 tread locking agent. Tighten
these bolts in succession, again checking for free play in the drive shaft. After all
boltsare 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 VALVES ARE OPEN!
STARTING AT THIS TIME WILL CAUSE SERIOUS DAMAGE TO THE PUMP.
HYDRAULIC TANK INSTALLATION
Install all fittings and tubes into tank and tank filter as shown in parts section
illustration. Insert tank sight glass into front side of the tank. Install the temperature
sensor or pipe plug into the side of the tank.
Place the tank in the mounting bracket on the main fame with fittings toward
tractor and filter toward the cab.
Secure the tank in the mounting bracket with the tank strap and nylock nuts.
Install the filter gauge into the filter housing so that it points to the rear of the
tractor and is clearly visible to the operator.
Locate the tank breather and reducer bushing (bushing may be already installed
in the tank along with many of the for-mentioned parts). These will be installed after
tank is filled.
INSTALLING NATIONAL PIPE FITTINGS
Whenever installing a pipe fitting, wrap the threads clockwise (looking at the
end) with teflon tape. In this way, the tape will be tightened when installed. NOTE:
It is not necessary to tape O-ring fittings, or those installed in swivels.
