Here is a solution posted by Beech Lister
O. for his leaking Gear Crank Handle:
safety wire remove three screws place rag under assembly to catch any dripping
oil tap on assembly to break it lose from gear box place small rag in hole where
handle came off--this keeps oil from draining out remove screw from handle slip
shaft out from other side remove O-ring (AN6227-9)
clean all parts and
inspect shaft for damage on end. See Picture
is a picture of the groove
for the O-ring
do NOT scar it getting the old O-ring out. After cleaning all
the parts, slip in a new O-ring, AN6227-9 or MS28775-111, using a small wooden dowel to help in
placement replace the washer and spring, lube shaft and slowly insert into housing.
3. Place shims on shaft while pushing in on shaft--place handle and insert screw
4. Place some RTV around facing that fits to gear box
handle assembly onto gear box--making sure that it is pointed upwards--NOT down.
5. Replace screws and safety wire all three -- note the slight upward angle of the handle
in the above photo on the left.
6. Test to make sure the handle engages the gear box properly then place cover back on
sure the handle is not caught under the cover.
7. You may want to consider leveling the aircraft to
insure that your oil level in the transmission is properly filled. Place a
cookie tray or rags under the handle area to catch any overfill that may be in
the transmission housing.
An easy fix to a dirty problem!
