Mains:
With the Retract Arm disconnected from the Rod End, move the cylinder to the “gear up” (retracted) position using
the aircraft pump. Then position the gear in the “gear up” position and hold in place through the top access hole in
the float.
Align the hole in the Rod End Clevis with the hole in the Retract Arm. The hole in the clevis should be 1/32-1/16”
below the hole in the retract arm. This adjustment must be accomplished by adding or removing washers under
the rod end lock nut. The in and out adjustment of the rod end on the threads is not critical at this time as long as
the lock nut is snug against the Rod End Clevis.
Again, using the aircraft pump, move the piston rod to the “gear down” (extended) position. Then position the gear
in the “gear down” position and hold in place through the top access hole in the float. Align the hole in the Rod
End Clevis with the hole in the Retract Arm. Adjust the Rod End Clevis so that the hole in it is 1/32-1/16” above
the hole in the retract arm and tighten the lock nut.
Nose and main gear proximity switches are set by sliding the mounting clips on the cylinders to a position such
that the light goes out when the cylinder piston is about 1/8 inch from the bottomed position while traveling in the
up direction. It should come on about 1/8 inch from the bottomed position while traveling in the down direction.
The system automatically bleeds, provided sufficient oil is maintained in the reservoir. To check the fluid level, fill
the reservoir with hydraulic oil and cycle the gear. If the reservoir empties (i.e., fluid disappears in sight glass),
stop the cycle by pulling the circuit breaker on the control panel. Fill the reservoir again and complete the cycle.
Continue this procedure until the fluid level in the reservoir stabilizes (it will vary in level between up and down
positions). If the fluid level continues to decline during gear cycles, check for external leaks. If pump cycles on
and off during gear cycle, it may be necessary to select hand pump to “UP.” Cycle gear up with electric pump.
Then select to gear “DOWN” on hand pump and cycle gear down with electric pump. Repeat if necessary. This
manually bleeds system. NOTE: Fluid level in reservoir in “UP” position is full. “DOWN” position reservoir is half
full. Don’t over fill in “DOWN” position.
Landing Gear Fails to Retract or Extend:
1. Battery Switch – ON
2. Landing Gear Switch – RECHECK IN DESIRED POSITION
3. Landing Gear Motor Circuit Breaker – CHECK IN
4. Hand Pump Position Selector – CHECK in NEUTRAL POSITION
5. Gear Lights – 4 BLUE for gear UP
4 GREEN for gear DOWN
6. Gear Position – CHECK VISUALLY
If gear still in improper position:
7. Landing Gear Switch – RECYCLE
8. Landing Gear Motor – CHECK RED LIGHT ON
9. Airspeed – REDUCE to minimize airloads on gear
If pump is running intermittently, or gear is not moving:
10. Hand Pump Position Selector – PLACE IN SAME POSITION as Landing Gear Switch.
