Adc Differential Hydraulic Circuit Bleeding; Disassembly / Inspection - Polaris Sportsman 800 EFI 4x4 2012 Service Manual

ADC Differential Hydraulic Circuit Bleeding

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 hydraulic bleeders.
3. Remove reservoir cap and diaphragm assembly.
4. Make sure hydraulic oil inside reservoir is free of
debris. If any debris is found, use clean rag or
suction device to remove from the reservoir.
NOTE: 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 Polaris ADC oil.
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
valve before oil level falls below minimum fill
line. Refilling empty reservoir will result in air
pockets becoming trapped.
If empty reservoir is encountered, filling of fluid
is still possible. Verify air is not trapped before
proceeding with step 7.
8. Continue steps 6-8 on both sides in sequence until
no air bubbles are seen when bleeding occurs.
9. Re-torque both bleeder valves to specification and
reinstall cover caps.
Bleeder Valve:
80 in-lbs (9 Nm)
10. Fill reservoir with to a level midway between 'MAX'
and 'MIN' fill lines. Verify no debris is found in
reservoir oil.
11. Replace reservoir cap securely and wipe clean any
residue.
