Ace Pump Flow Limiter (Option)
Refer to Page 33 Figure 27
The flow limiter is a hydraulic device designed to
shut off the flow of hydraulic oil when a specified
flow is exceeded. On tractors with LOAD SENS-
ING (LS) Closed Center hydraulic systems, this
device limits the flow of oil to the Ace motor and
prevents failures due to misapplication.
The new Case-IH, John Deere, New Holland, and
CAT tractors, present a great potential to turn the
motors beyond their rated speeds. Flows out of the
hydraulic valves can exceed 20 GPM while the
motors are rated at 4-11 GPM. The flow limiter
protects the Ace motor by shutting off when hy-
draulic flows exceed the motor’s capacity.
The flow limiter should not be used on OPEN cen-
ter or PRESSURE COMPENSATING Closed
Center hydraulic systems. The flow limiter should
not be used with a restrictor orifice.
To Install:
1. Install the flow limiter in the inlet port of the
Ace motor.
2. Close the needle valve on the Ace motor by
loosening the jam nut and screwing the nee-
dle valve in a clockwise direction all the way
down.
3. Connect the hydraulic hoses so that the pump
runs with the hydraulic lever in the “Lower/Re-
tract” position. Connect return hose to Low
Pressure Return Port, when available.
4. Shut off boom and agitation valves on the
sprayer to deadhead the sprayer pump flow.
5. Adjust the flow control on the tractor to mini-
mum flow setting (turtle).
6. Move the hydraulic lever to the “Lower/Re-
tract” position. NOTE: Always shut the pump
off in the “Float” position. This eliminates high
pressure being trapped in the return line and
protects hydraulic seals. Avoid returning the
oil to the remote valve; use the Low Pressure
Return port, when available.
7. Adjust the flow control on the tractor until the
sprayer system deadhead pressure is 80 psi.
NOTE: If the flow limiter stops the flow of oil to the
motor: 7a) Move the hydraulic lever to the “Neu-
tral” position. This removes the oil pressure from
the flow limiter and allows it to reset. 7b) Adjust the
flow control to a lower flow position. 7c) Repeat
steps 6 and 7.
8. Set sprayer pressure by opening the agitation
valve.
