Adc Differential Hydraulic Circuit Fluid Change (6X6) - Polaris Sportsman 800 EFI 4x4 2012 Service Manual

MAINTENANCE
ADC Differential Hydraulic Circuit Fluid
Change (6x6)
Service Note: Under extreme use, change ADC fluid
every 25 hours. "Extreme Use" is defined as constant
ADC operation on hilly or mountainous terrain, or if ADC
'on' is the primary mode of AWD operation.
1. Make sure vehicle is parked on flat ground and
allowed to sit at least 30 minutes prior to bleeding
hydraulic circuit.
2. Thoroughly clean area around and on remote
reservoir and bleeder valves.
3. Remove reservoir cap and diaphragm assembly.
4. Make sure fluid inside reservoir is free of debris. If
any debris is found, use a clean rag or suction device
to remove from the reservoir.
WARNING
Debris in reservoir may block porting and produce
inadequate bleeding of the system. Decreased
performance may be encountered with inadequate
bleed of the hydraulic circuit.
5. Begin the bleeding process by filling reservoir to
'MAX' line with clean Demand Drive fluid.
6. Locate bleeder valves found on either side of
differential and remove the protective caps.

7. Turn bleeder valves counter-clockwise to loosen.
Loosen bleeder screw slowly, allowing oil and any
trapped air to flow out of fitting.
NOTE: Do not allow hydraulic fluid in reservoir
to drain below minimum fill line. Close bleeder
valves before oil level falls below minimum fill
line. Refilling empty reservoir may result in air
pockets becoming trapped.
If an empty reservoir is encountered, filling of
fluid is still possible. Verify air bubbles are not
trapped in the reservoir line before proceeding
with step 7.
8. Continue steps 6-8 on both sides in sequence until
clean fluid is seen when bleeding occurs.
9. Re-torque both bleeder valves to specification and
reinstall cover caps.
10. Fill reservoir with Demand Drive to a level midway
between 'MAX' and 'MIN' fill lines. Verify no debris is
found in reservoir.
11. Replace reservoir cap securely and wipe clean any
residue.
