Traction Circuit Testing − Charge Pressure Test (continued)
13. Record reading on pressure gauge from the mower manifold CHD port.
Charge pressure (without load) should read from
10.3 to 13.8 Bar (150 to 200
PSI)
. If charge relief pressure specification is not met, consider the following:
A. Gear pump (P2) is faulty (steering/lift circuit performance will also be
affected). Test gear pump (P2) flow (refer to
Circuit Testing − Gear Pump (P2) Flow Test (page 5–55)
).
B. The piston pump charge relief valve is faulty. Repair or replace the piston
pump charge relief valve (see
Piston Pump/Hydrostat Service (page
).
14. Sit in the operator’s seat, release the parking brake, and slowly depress the
forward traction pedal until
68.9 to 103.4 Bar (1000 to 1500 PSI)
is reached
on the flow meter pressure gauge.
15. Record reading on pressure gauge from mower manifold CHD port (under
load). Charge pressure (under load) should not drop more than 20% when
compared to charge pressure (without load) recorded in step
.
If specifications are not met, perform
Traction Circuit Testing − Piston
Pump/Hydrostat (P3) Flow and Relief Pressure Test (page 5–37)
.
16. Release traction pedal, move throttle to low speed and turn the engine off.
