FREESPOOL Pressure Check
All installations with optional
DRAG-BRAKE
Test Equipment:
•
(1) 1,000 psi (6,895 kPa) Gauges
Connect pressure gauges to port:
•
FR (Tee into existing line)
Instructions
1. With the engine shut off, use tees and fi ttings as
available to connect a 1000 psi pressure gauge to
the
FR
port.
2. Start dozer and set to high-free idle
3. Measure pressure with the
FREESPOOL
switch
activated.
4. Check pressure. The pressure at this port should be
equal to the pilot supply pressure from the dozer.
FREESPOOL
requires 170 psi to release. Low
pressure will not allow for full disengagement of gears
for
FREESPOOL
function.
If pressure is not at least 170 psi, check for:
1. Improper pilot supply pressure.
2. Malfunctioning solenoid valve.
3. Leaking pressure hoses or fi ttings.
4. Restriction in pressure hose or manifold port.
5. Leaking in gear side of winch. Watch oil level at the fi ll
level plug to determine if there is leaking in gear side.
