Main Landing Gear Bushings Installation
The main landing gear mount fittings have grease fittings installed for lubrication. There are two
installations. For the first parts we made, straight grease fittings are installed, and we have
subsequently changed the design of the fitting to accept angled grease fittings. It is not possible to
get a grease gun on the straight grease fittings, so a needle adaptor is used. The tip of this
oversized hypodermic needle is inserted into the tip of the grease fittings and grease is pumped in.
❏
Remove P/N 766 from the wing spar and install P/N 769. This bushing is a press fit. It
will require that you tap it in to place. Use a board on the bushing and tap the bushing
into place. As an alternative method you may do a “shrink fit” installation. Under this
method P/N 766 is heated in an oven while the bushing is placed in a refrigerator. This
will expand P/N 766 while shrinking the bushing. Remove the fitting from the oven and
the bushing from the refrigerator and quickly put the bushing in the fitting.
❏
Remove P/N 767 from the forward wing spar and install P/N 770. This bushing is a press
fit. It will require that you tap it in to place. Use a board on the bushing and tap the
bushing into place. As an alternative method you may do a “shrink fit” installation.
Under this method P/N 767 is heated in an oven while the bushing is placed in a
refrigerator. This will expand P/N 767 while shrinking the bushing. Remove the fitting
from the oven and the bushing from the refrigerator and quickly put the bushing in the
fitting.
❏
For the installation of straight grease fittings in P/N 766—drill through the bushing with a
#3 (.213ӯ) drill, then tap with a 1/4-28 tap. The grease fitting should be installed on the
inboard face so you will have to drill a new hole on one `P/N 766. Install the straight
grease fitting, Lincoln No. 5013, so that it enters the hole in the bushing. The object of
the installation is to deliver grease to the groove inside the bushing, and the grease fitting
should prevent the bushing from turning. If you wish, you can install a 45° Lincoln
No. 5212.
❏
For the installation of the 45° grease fittings in P/N 766—drill through the bushing with a
#3 (.213ӯ) drill, then tap with a 1/4-28 tap. Install the grease fitting, Lincoln No. 5212,
so that it enters the hole in the bushing. The object of the installation is to deliver grease
to the groove inside the bushing, and the grease fitting should prevent the bushing from
turning. To install the grease fitting, the tiny grease fitting must be unscrewed from its
base—it is held in place with Loctite—and then reinstalled with Loctite after the base is
screwed in place.
❏
For the installation of straight grease fittings in P/N 767—drill through the bushing with a
3/16ӯ drill and then install the Lincoln No. 5033 grease fitting. This is a drive type of
grease fitting and may be installed in the threaded hole provided. (At the time we made
the part, we were under the impression that you can get grease fittings with 10-32
threads—you can’t.) An angle grease fitting cannot be installed in the early-model P/N
767.
