description: P Series Flow test Kit (Part number 70661)
(Part number 70661 Supersedes Part numbers 70511 and BB-76810)
Purpose: The design purpose of the P Series Flow Test Kit is to allow the customer to isolate the pump from the
wheel motor and determine if the pump is acceptable. The following information can be used to install and test the
pump by simulating a wheel motor load.
1. Disconnect the system hoses at the wheel motor, or system hoses from the pump and connect the
P Series Flow Test Kit. (Special care should be taken to prevent contamination debris from entering
pump or wheel motor system ports)
cautIon: Ensure all fittings and hoses are attached securely. This test is being completed on the
vehicle’s high pressure system lines. Failure to perform this properly could result in bodily injury.
1. Raise the drive tires off of the ground. Block the remaining tires on the ground to prevent accidental
vehicle movement.
2. Open the restriction valve all the way.
3. Make certain all external pump directional control stops are removed or backed off on the vehicle
linkage to obtain full pump directional control arm travel.
4. Start the engine and engage the drive pulley if necessary.
5. Bring the engine to maximum operating speed.
cautIon: Ensure all fittings and hoses are attached securely. This test is being completed on the
vehicle’s high pressure system lines. Failure to perform this properly could result in bodily injury.
(this should not exceed 3600 rpm input speed on the Pc, Pl, PG, Pe, PK and PJ Series Pumps)
(this should not exceed 3400 rpm input speed on the Pr)
(this should not exceed 2800 rpm input speed when testing the PW)
engine speed adjustment may be necessary to obtain 2800 rpm.
6. With the directional control lever (on the vehicle) for the pump being tested, move the control arm in
full forward motion. (It may be necessary to lock the control arm into full forward position to prevent
false readings).
7. Operate without any load for approximately 30 seconds to 1 minutes. This allows the system oil tem-
perature to rise.
WarnInG
do not attempt any adjustments with the engine
running. use extreme caution while working in
or around all vehicle linkage! High temperatures
can be generated. Follow all safety procedures
outlined in the vehicle owner’s manual!
WarnInG
certain procedures require the vehicle engine
to be operated and the vehicle to be raised off
of the ground. to prevent possible injury to the
servicing technician and/or bystanders, insure
the vehicle is properly secured.

teStInG ProcedureS:
note: Using the Bi-Directional Flow Test Kit, determination of directional flow is not necessary. The flow
meter may be connected in either direction into the forward and reverse high pressure system lines.
