PROBLEM: HYDRAULIC CHUTE ROTATION IS SLOW OR DOES NOT TURN
When activating the chute rotation, it turns very slowly or not at all.
WARNING To avoid serious
personal injury, always wear safety glasses
while doing the instructions below.
SOLUTION:
1. Check if the tractor valve works well. Test it by
plugging another piece of equipment to the
valve. If it does not work well, refer to the
appropriate operator's manual.
2. Check if the chute alone turns well by
removing the bolt (item 6) and the gear
(item 5) of the hydraulic motor (item 3) then
manually rotate the chute in both directions. If
it does not turn well, correct the problem by
checking for excess wear or debris stuck
between the components.
3. If the chute turns well manually, but it turns
well in one direction with the hydraulic motor,
check if there are residues in the hydraulic
circuit by removing the bolt, lock washer, flat
washer (item 6) and the motor gear (item 5)
(item 3) then activate rotation in the direction
in which the motor runs well for about 1 minute
to evacuate the residues.
4. Rotate the chute in the direction it did not turn
to see if the problem is corrected. If the
problem persists or if the chute does not turn
well in both directions, release the pressure
from the system: turn the ignition key to ON
without starting the engine, activate the float
mode with the control handle and turn the
ignition key to OFF.
5. Disconnect the hoses from the engine,
remove the 2 adapters (item 4) and carefully
inspect the orifices of the 2 engine flow
limiters (items 3a-3b). Remove residue, if any,
with compressed air. If no residue is found,
disconnect the hoses and clean with
compressed air.
IMPORTANT: When disconnecting the
connectors, be sure to always install the
protective plugs and caps on the hydraulic
connectors of the tractor hoses and valve to
prevent contamination of the hydraulic circuit
and clogging of the orifices of the flow
restrictors of the tractor. hydraulic motor.
