Pump & Gearbox Assembly
Refer to Figure 1-3:
The pump, capable of 25 gpm @ 540 rpm, is
mounted under the reservoir tank and connected
to tractor power take-off shaft with a driveline.
1. Separate pump rear guard (#3) from high
speed pump mount (#2).
2. Verify gearbox (#12) is full of oil.
a. Rotate high speed pump mount (#2) onto
its right side plate “D”.
b. View sight glass in gearbox (#12). Oil
should be visible in sight glass. Some
tipping of unit and a flashlight may be
needed to see oil line.
c. If low or out of oil, remove sight glass and
add recommended gearbox oil provided
on page 34.
3. Screw 1 5/16" MJIC x 1 5/16" MORB
elbow (#17) to “OUT” port of hydraulic
pump (#11) until snug.
4. Screw 1 5/8" MORB x 1 1/4" HB elbow (#15)
to the “IN” port of hydraulic pump (#10) until
tight.
5. Center hydraulic hose (#1) in slot “D” and
screw hydraulic hose to elbow (#17) as
follows:
•
No valve Option:
Screw 1" x 40" long
hydraulic hose (#1) to elbow (#17) until
tight.
•
Manual & Solenoid Valve Option:
Screw
1" x 34" long hydraulic hose (#1) to
elbow (#17) until tight.
6. With hydraulic hose (#1) centered in slot “D”,
tighten elbow (#17) to hydraulic pump (#11).
7.
Attach high speed pump mount (#2) to
reservoir tank with 1/2"-13 x 1 1/2" GR5 cap
screws (#6), spring lock washers (#10), and
hex nuts (#8). Tighten nuts to the correct
torque.
8. Remove cap from nipple “B” and apply teflon
tape to nipple. Screw ball valve (#13) to pipe
nipple “B” until tight with control lever on top.
9. Apply teflon tape to elbow (#14) and screw
elbow onto ball valve (#13) until tight with
elbow turned down as shown.
10. Attach suction hose (#16) to elbow (#15) with
worm drive clamp (#4) and tighten.
11. Attach suction hose (#16) to elbow (#14) with
worm drive clamp (#4). Make sure suction
hose passes through slot “C” and tighten
worm drive clamp (#4).
12. Tighten elbow (#15) to hydraulic pump (#11).
