Procedure for Traction Drive Hydrostat (P3) Flow

Test

This test measures hydrostat pump output (flow). Dur-

ing this test, pump load is created at the flowmeter using

the adjustable load valve on the tester.

1. Make sure hydraulic oil is at normal operating tem-

perature by operating the machine for approximately ten

(10) minutes.

2. Park machine on a level surface with the cutting

units lowered and off. Make sure engine is off. Make

sure the hydraulic tank is full.

CAUTION

Before continuing further, read and become fa-

miliar with Precautions for Hydraulic Testing.

3. Make sure that traction pedal is adjusted to the neu-

tral position (see Traction Pedal in the Adjustments Sec-

tion). Also, ensure that pump is at full stroke when

traction pedal is pushed into fully forward position.

4. Block up front wheels off the ground (also rear

wheel if machine is equipped with 3WD) to allow flow

through the traction circuit.

5. Disconnect hose from the upper hydraulic fitting on

the side of the hydrostat.

6. Install tester with pressure gauge and flow meter in

series with the pump and the disconnected hose.

Make

sure flow control valve on the tester is fully open.

7. Make sure functional lever is in the transport posi-

tion.

8. Start engine and move throttle to full speed

(2750 +

50 RPM)

position.

CAUTION

The drive wheels will be off the ground and rotat-

ing during this test. Make sure machine is well

supported so it will not move and accidentally

fall to prevent injuring anyone near the machine.

9. Slowly push traction pedal into fully forward posi-

tion.

10. Slowly close flow control valve until pressure gauge

reads

1000 PSI (69 bar)

11. Observe flow gauge. TESTER READING should be

a minimum flow of

12.5 GPM

. Record test results.

12. Release traction pedal, open control valve on tester,

and turn off machine.

13. If specifications are not met consider the following:

A. The traction pedal and/or traction speed may

need adjustment (see Traction Pedal in the Adjust-

ments Section).

B. The hydrostat needs to be repaired or replaced

as necessary.

C. Make necessary repairs before performing addi-

tional tests.

14. If specifications are met, check wheel motor effi-

ciency (see Wheel Motor Efficiency Test in this section).

15. If testing is complete, disconnect tester from pump

fitting and hose. Reconnect hose to pump fitting.
