Procedure for Reel Drive Pump Efficiency
Check:
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. Make sure the hydraulic tank is full.
CAUTION
Operate all hydraulic controls to relieve
system pressure and avoid injury from
pressurized hydraulic oil.
4. Clean hose connection and reel drive pump. Dis-
connect hose connection on the reel drive pump leading
port P1 on the hydraulic manifold.
IMPORTANT: Make sure oil flow indicator arrow on
the flow gauge is showing that the oil will flow from
the pump through the tester and into the valve
block.
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. Make sure backlap knob on the valve block is in the
mow position.
7. Make sure tester load valve is fully before starting
the engine.
8. Start engine and move throttle to full speed (3200 "
100 RPM). Do not engage the cutting units.
9. Watch pressure gauge carefully while slowly clos-
ing the flow control valve until 1500 PSI is obtained.
Verify with a phototac that the pump speed is 2900 RPM.
10. Flow indication should be 5.4 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 5.4 GPM or a pressure of 1500
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.
