ASSEMBLY
BUMPER HYDRAULIC TANK INSTALLATION
Install all fittings and tubes into tank and tank filter as shown in the parts section
illustration. Insert tank sight glass on the inner right side of the tank. Install the
temperature sensor (optional), or pipe plug into side of the tank.
Attach the large mounting brackets on the front casting of the tractor. Secure the
brackets to the tank with the hardware shown in the parts section.
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. The breather cap will be installed after tank is
filled.
FRONT PUMP MOUNTING
Install the pump mounting bracket on the front of the tractor with capscrews and
lockwashers 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 on
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 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 AND TANK IS FILLED WITH PROPER OIL! STARTING THE TRACTOR
AT THIS TIME WILL CAUSE SERIOUS DAMAGE TO THE PUMP.
TEMPERATURE GAUGE MOUNTING
(OPTIONAL)
Mount the temperature gauge where it is clearly visible to the operator. Attach the
green (-) wire from the negative post on the gauge to a grounded bolt on the tractor
frame. Remove paint if needed to make a good ground. Remove the pipe plug from the
side of the hydraulic reservoir, and install the temperature sensor using thread sealing
tape. Run the white wire from the (s) sensor post of the gauge to the temperature
sensor on the hydraulic reservoir tank.
