Figure 29-10. End Gland Locking Device
DISASSEMBLY OF MAIN GEAR ACTUATING CYLINDER. (Refer to Figure 29-11.)
1. With the cylinder removed from the airplane, push the piston rod (by hand) toward the clevis to
remove oil from the unit.
2. Put clevis only in a soft jaw vise and clamp against the clevis bearing.
3. If no pipe fitting is installed in the port of the end gland, install a fitting (1/8-27) into the port. This
fitting need not be tight as it will be used for leverage only.
4. Rotate the gland (with use of fitting) until the end of the gland lock ring shows in the slot in the
cylinder body. Reverse rotation of the gland to allow the lock ring to move out of the slot. (Refer to Figure 29-
10.) (It may be necessary to give the ring an assist to start out of the slot. If so, insert a strong wire pick or
other available tool in the slot to lift up the end of the ring and then rotate gland.)
5. Pull the piston and end gland from the cylinder.
6. Remove O-rings or T-seal as desired.
CLEANING, INSPECTION AND REPAIR OF MAIN GEAR ACTUATING CYLINDER.
1. Clean the cylinder parts with a suitable dry type solvent and dry thoroughly.
2. Inspect the cylinder assembly for the following:
A. Interior walls of cylinder and exterior surfaces of piston for scratches, burrs, corrosion, etc.
B. Threaded areas for damage.
C. End fitting retainer slot for excess wear.
D. Rod end fitting and swivel fitting of cylinder for wear and corrosion.
3. Repairs to the cylinder are limited to polishing out small scratches, burrs, etc., and replacing parts.
Refer to parts catalog for correct replacement part numbers.
