Procedure for Gear Pump (P1) Check:
7. Make sure tester load valve is fully open before
1. Make sure hydraulic oil is at normal operating tem-
perature by operating the machine for approximately 10
minutes.
2. Make sure machine is parked on a level surface with
the cutting units lowered. Make sure engine is off and
the parking brake is engaged.
3. Read Precautions for Hydraulic Testing.
4. Disconnect hose connection on the reel drive pump
leading to port P1 on the hydraulic manifold.
5. Install tester in series with reel drive pump and the
disconnected hose leading to port P1 of the hydraulic
manifold. Make sure the flow control valve is fully open.
6. If a backlap kit is installed, make sure backlap knob
on the valve block is in the mow position and reel speed
is set to maximum.
starting the engine.
8. Start engine and move throttle to full speed. Do not
engage the cutting units.
A. Units with a diesel engine (3025
"
50 RPM).
B. Units with a gasoline engine (2800
"
28 RPM).
9. Watch pressure gauge carefully while slowly clos-
ing the flow control valve until 2000 PSI is obtained.
Verify with a phototac that the pump speed is as speci-
fied in step 8.
10. Flow indication should be 5.5 GPM minimum.
11. Shut off engine.
12. Disconnect tester from manifold and hose. Recon-
nect hose to the pump.
13. If flow was less than 5.5 GPM or a pressure of 2000
PSI cannot be obtained, check for restriction in the pump
intake line. If line is not restricted, remove pump and re-
pair or replace as necessary.
