WARNING
Before beginning any service work turn off the
PTO, set the parking brake, turn off the ignition,
and disconnect the spark plug wire(s).
REMOVAL & INSTALLATION
1. Park machine on a flat, level surface and engage the
parking brake.
Figure 2. Fitting Orientation
2. Remove and discard the fuel tank tie bar and the left
and right mounting brackets. SAVE the mounting
hardware.
NOTE: Some oil loss will occur when disconnecting the
hydraulic hoses. Remove and reconnect as quickly as
possible and prepare to contain the lost oil.
3. Remove the split collars from the control cross shaft
and carefully lift the shaft assembly from the saddles.
Set the shaft on the ledge of the rear seat support to
allow for increased access room.
5. Remove the right return hose and loosen the jam nut
on the fitting on the pump. Rotate the fitting towards
the rear of the machine and point it slightly upwards
(see Figure 2). Tighten the jam nut.
4. Subassemble the 19” and 25” hose lengths with one
of the barbed fittings on each hose and the appropri-
ate length of wire loom. Be sure the barbs are fully
inserted into the hose end. Applying a few drops of
oil on the barbs will make the assemble easier.
6. Install the 19” hose assembly to the fitting on the
pump and tighten. Leave the free end of the hose
higher than the reservoir to prevent to hydraulic sys-
tem from draining.

19. Refill the oil reservoir to the “MAX OIL LEVEL HOT”
line. Use either Mobil 1, 15W-50 synthetic oil or
Castrol Syntec 5W-50 oil. DO NOT use conventional
oils. Make sure area around the reservoir is free of
dust, dirt, or other debris.
20. Reinstall the left drive tire and remove the jack
stands. Lower the seat plate.
21. Make sure the parking brake is engaged, the control
handles locked in the “NEUTRAL” position and the
PTO switch is off. Reconnect the spark plug wires.
22. Start the engine and run it in the slowest throttle
position. Dismount the machine and raise the seat
plate.
23. Carefully watch the oil level in the reservoir while the
machine in running. The level will initially drop quick-
ly as the oil coolers are being filled. Do not allow the
oil level to drop below 50% of the full capacity.
Figure 6. Tie Wrap Location
24. With the cap removed, look through the filler neck of
the oil reservoir and watch for oil flow at the return
line barbs. Once there is a continuously flow of oil,
the return side of the hydraulic system has been
filled. If necessary, fill the oil reservoir to 1/2” below
the “MAX OIL LEVEL HOT” line.
25. Replace the oil reservoir cap and lower the seat
plate.
