hex with a wrench before pressing on the strut valve. Sand the 37.9Ø ridge of the piston
until the piston will fit into the oleo nut, then carefully clean the piston to remove all
sanding grit. Oil the piston and reassemble the oleo strut. See Drawing No. 550.
Note:
P/N 554 has a 38mm diameter counterbore (see Drawing No. 554) into which the
37.9Ø ridge of the piston fits (see Drawing No. 555-3). Oil is trapped in this area when
the oleo extends. The purpose of this is to cushion the shock and to keep the oleo strut
from “knocking” metal against metal when the oleo is fully extended. During the
manufacture of the oleo shock absorbers, the pistons are chrome plated. The chrome
plating tends to build up with a heavier coating on the raised part. This makes the
diameter of the piston’s land slightly too large. This can be reduced by sanding with a fine
grit emery paper (320 grit). Do not attempt to use a file as the chrome is much harder
than the file and will only dull it.
❏
Split the main wheel by loosening the six bolts.
❏
Shake some talcum powder inside the tire.
❏
Install the inner tube in the tire.
❏
Place the tire and tube on the side of the wheel with the hole for the inner tube valve
stem. Pull the valve stem through the hole.
❏
Put enough air pressure in the inner tube to round it out, but not enough so that it starts to
expand.
❏
Install the other side of the wheel and insert the bolts. Be very careful to make sure that
you do not pinch the inner tube between the two halves of the wheel.
❏
Tighten the nuts and bolts for the wheel.
❏
Inflate the wheel to about 30 psi. Remove the valve core and allow the tire to deflate.
Then replace the valve core and inflate the tire to about 30 psi.
❏
Install the wheel on the axle. If the nut is a little short of the cotter pin hole, deepen the
slots with a hacksaw.
❏
Install the landing gear arm on the landing gear leg.
❏
Install the oleo shock absorber on the landing gear leg.
❏
The landing gear parts may be painted at any time. It is suggested that the inside of the
upper tube of the landing gear leg be coated with par-al-ketone and zinc chromate primer.
Do not paint the two bearing surfaces of the landing gear leg, i.e., where the leg pivots in
the fittings installed in the wing.
