Front Gearcase ADC Fluid
NOTE: It is important to follow the front gearcase
maintenance intervals described in the Periodic
Maintenance Chart. Regular fluid level inspections
should be performed as well.
The front gearcase ADC fluid level should be checked and
changed in accordance with the maintenance schedule.
Front Gearcase ADC Fluid Level Check
The ADC fluid reservoir is located underneath the front rack as
shown below. Maintain the fluid level between the “MIN” and
“MAX” levels indicated on the reservoir.
1. Disengage the anchors and remove front rack assembly.
2. Check the fluid level of the ADC reservoir.
3. If fluid level is below the minimum mark on the reservoir,
remove the cap and add the recommended fluid.
4. Reinstall the cap and front rack assembly.
Front Gearcase ADC Fluid Change:
1. Position the vehicle on a level surface and allow the
vehicle to sit for at least 30 minutes.
2. Thoroughly clean the areas around the ADC reservoir and
bleeder valves.
3. Remove the reservoir cap and diaphragm assembly.
4. Make sure the fluid inside the reservoir is free of debris. If
any debris is found, use a clean shop towel or suction device
to remove it from the reservoir.
NOTE: Debris in the reservoir may result in
inadequate bleeding and reduced performance of
the system.
5. Begin the bleeding process by filling reservoir to the
“MAX” level with clean ADC Front Drive Fluid.
6. Locate bleeder valves found on each side of the front
gearcase and remove the protective caps.
7. Attach a clean clear hose to one of the bleeder valves.
8. Slowly loosen the valve (counter-clockwise) and allow
fluid and trapped air to flow from the fitting.
IMPORTANT: Do not allow ADC fluid in reservoir to
drop below the “MIN” fill line. Close bleeder valve
before the fluid level drops below the “MIN” fill line.
Refilling an empty reservoir will result in air pockets
becoming trapped.
9. Close the valve when clean (bubble-free) fluid begins to
flow from the valve.
10. Repeat steps 7-9 on the remaining bleeder valve.
11. Torque the bleeder valves to specification and reinstall the
protective caps.
12. Fill reservoir to a level midway between “MAX” and
“MIN” fill lines. Verify no debris is found in reservoir
fluid.
13. Install the reservoir cap and diaphragm securely and wipe
clean any fluid residue.
