Standby Pilot Supply Pressure Check
With the engine shut off, connect a 1000 psi gauge to the
tractor pilot test port. This is behind the battery access
panel and is the quick-connect port on the pilot reducing
manifold (see tractor Service Manual). Start the engine
and follow procedure in Figure 3-6. Adequate standby pilot
supply is required for both tractor and winch functions.
If the pressure is not as specified, check for:
1.
Improper pilot supply reducing valve setting or mal-
function (See tractor Service Manual)
2.
Pump standby pressure setting incorrect (See tractor
Service Manual)
3.
Leaking pressure hoses or fittings
Maximum Pilot Supply Pressure Check
With the same gauge installed from the Standby Pilot
Pressure Check, bottom tractor blade cylinders and
measure Relief Pilot Supply Pressure. When the tractor
pump senses a load, the maximum pilot supply pressure
is reduced to the setting of the tractor pilot reducing valve.
Excessive pilot supply pressure may cause damage to
tractor and winch components.
If pressure is not as specified in Figure 3-6, check the
following:
1.
Improper pilot supply reducing valve setting or mal-
function (See tractor Service Manual)
2.
Leaking pressure hoses or fittings
