Removal And Installation Of The Undercarriage (Main Wheel); Undercarriage (Main Wheel), Version Without Nose Wheel - DG Flugzeugbau DG-1000T Maintenance Manual

4.5 Removal and installation of the undercarriage (main wheel)

4.5.0 General
Warning: A gas strut is installed inside the landing gear box to compensate the
mass of the landing gear. The landing gear may retract by itself when unlocked
by the force of the gas strut, especially when the glider is not in the normal
position. So when working on the landing gear make sure that inadvertent
retraction of the landing gear is prevented.
Removal of the gas strut in the landing gear control system: Use a screw
clamp to pre-stress the gas strut sufficiently so that the bolts can be removed.

1. Remove axis 10FW11/7 together with the 2 parts 10FW11/2.
2. Remove the wheel axle 10FW11/6 and the bush 10FW11/4.
3. Move the wheel with the brake assembly to the right, so that the pin of
part 10FW18 slides out of the fork 10FW11/1. Now remove the wheel
with the brake assembly.
B Removal of the brake assembly from the main wheel
1. This is only necessary if the tyre is to be removed or if the brake linings
are to be exchanged.
2. Remove the 2 bolts A from the brake assembly.
3. Take off brake assembly with holder 10FW18 and take away the loose
part (back plate assy.) with the brake lining.

Caution: Don't operate the airbrake and thus the wheelbrake with brake
assembly disassembled, as the piston and the brake-fluid will be pressed out of
the brake assembly.
