If a Faulty Draper Motor is Suspected
●
Let the system cool down.
●
Start up and run draper at full speed. Record the pressure on the pressure gauge.
●
Check if any motors seem to be running slower.
●
Check temperature of each motor to see if one motor is hotter than the others.
●
SHUT COMBINE DOWN.
●
Grab the drive roller of a deck with both hands and rock the roller back and forth. If
motor is hard to turn, disconnect hoses and install a fitting to bypass the motor.
●
Record the difference in pressure, and draper speed of the other decks. If the
difference is significant, replace the motor.
Other Possible Causes for Excessive Pressure
Check the header’s hydraulic system for hydraulic lines or hoses that have been pinched or
kinked. Replace any damaged hydraulic lines or hoses. Do not attempt to repair or replace
leaking hydraulic lines or hoses without proper safety equipment and clothing, as high
pressure fluid leaks can puncture the skin causing injury or death.
Ensure the combine return line is properly connected.
Above normal pressure may also result if the pump is not adjusted to the shaft RPM. Check
that the knife is in the proper RPM range.
In certain harvesting conditions (such as a tough or heavy crop), the operating
pressure of the header will be higher than usual. In cases such as this, it may
be necessary to reduce the ground speed of the combine (in order to reduce
the demand for overall operating pressure of the header). An alternate
procedure would be to increase the pressure setting of the relief valves. Do not
adjust the relief valves to pressures above 3,000 psi.
Adjusting the Relief Valve
In certain harvesting conditions, it may be necessary to
adjust the relief valves in order to increase the output
and allow for efficient harvesting of the crop. If you are
harvesting in tough or heavy crop conditions, and an
audible squeal can be heard coming from the relief
valve, this may be the case.
The relief valves are factory set at 2,800 psi, and can
be adjusted up to a maximum of 3,000 psi. To increase
the pressure setting of the relief valve, proceed as
directed on the following page.
