5.1 JACK INSTRUCTIONS (continued)
WARNING!
This jack must be used with either a main gear pad or nose adapter. Damage may occur or
aircraft may fall off if pad or adapter are not used.
To Raise Main Gear:
1. Place jack on hard level surface.
2. Connect the pump hose.
3. Open the reservoir vent screw.
4. Place main gear pad (Part Number: R-1820) over mechanical extension.
5. Adjust mechanical extension so the pad is approximately one-quarter inch (0.25 in/0.63 cm)
below the bottom of the jack pad on the aircraft.
6. Place the jack between the tires and check the clearance between the mechanical extension and
the bottom of the jack pad. Measurement should be approximately one-quarter inch (0.25 in/0.63
cm).
7. Close pump release valve and slowly begin to pump the jack to raise the aircraft wheel. Verify
that there is clearance between the jack cylinder assembly and the brake casting.
6.0 MAINTENANCE
6.1 GENERAL
•All maintenance and/or repair work should be done using good workmanship practices and
proper tools.
•The work area should be clean and free of dirt.
•When O-rings and backup rings are removed, every effort should be made to avoid the contact of
tools with the critical surfaces of parts. Surface deformities could cause degradation of seals and
failure.
•It is good practice to replace all O-rings and backup rings once removed. Cut and damaged rings
normally result in fluid leakage.
•At this time flush old hydraulic fluid and dirt from overall system and replenish with new, clean
MIL-H-5606A hydraulic fluid.
6.2 SERVICING JACK
To Disassemble Jack:
1. Collapse jack ram.
2. Remove cap screws (Item 4) surrounding jack cylinder, then remove retaining ring, (Item 3).
3. Lift cylinder from axle jack base weldment (Item 2). Operate jack hand pump to help remove
cylinder. Separate rams by removing internal rings (Items 9, 10 & 11).
To Re-assemble Jack:
1. Replace all seals including internal rings.
2. Re-assemble in reverse order of above.
3. Torque each cap screw (Item 4) to between 75 −85 ft-lbs (101.69 −115.24 N-m), using standard
cross torque procedure.
To Bleed Jack for Air:
1. Open reservoir vent screw on hand pump.
2. Pump unit to fully extended position.
3. Turn jack upside down.
4. Push jack back to fully collapsed position.
