Ace PTO Pump Hookup
DANGER
!
Entanglement hazard - Keep hands, hair, loose clothing, lan-
yards and feet well away from a rotating PTO drive line. Shut
off tractor completely before hitching, unhitching, or making
any adjustments to or near the PTO.
1. 540 (rpm) PTO Pump:
Attach the pump to the tractor PTO shaft by tighten-
ing the three screwdriver slotted set screws and jam
nuts in the coupler. Make certain the set screws are
in line with the retaining groove on the tractor PTO
shaft.
1000 (rpm) PTO Pump:
Attach the pump to the tractor PTO shaft. Make sure
screwdriver slotted set screws are aligned with
retaining groove on tractor PTO shaft
- BUT DO NOT TIGHTEN.
Next, align the split in the slit-ring locking collar with
corresponding split in the pump drive shaft. Securely
tighten the
5 ⁄
16
in hex head set screw in the locking
collar, then tighten the three slotted head set screws
and jam nuts.
2. To keep the pump body from rotating with the tractor
PTO shaft, affix one end of a torque chain to the
“cold shut” shackle on the pump, and one end to the
tractor.
3. Securely attach the torque bar chain to the tractor
drawbar. Allow just enough slack to permit a full
range of three point hitch operations, such as raising/
lowering, and leveling.
Note: Do not fasten the pump rigidly in position with the
Torque Chain. To do so will cause damage to the
pump. Fasten the pump so that the chain holds the
pump and that there can be slack in the chain.
4. Rotate the pump housing in the direction of PTO
rotation, to the full extension of the chain. If a tarp
strap is available, use it to hold the pump at full chain
extension through the full range of three point hitch
operations. This prevents the torque arm from snap-
ping the chain to full extension at PTO startup.
Ace PTO belt driven centrifugal pumps may be swung to
the bottom, top or either side of the tractor PTO shaft in
order to make it fit a particular tractor. The pump oper-
ates satisfactorily in all these positions.
IMPORTANT !
Remember that the discharge port in the volute should
always be at the top (the 12 o’clock or 3 o’clock posi-
tion) to aid in priming.
