Subject: | Additions to Vic Syracuse's Sport Aviation article this month |
I sent this to the editor today.
Vic Syracuse did a good job on care and feeding of tires and brakes in the
Feb 2021 issue, but please allow me to add my top tips. Change tires and
tubes in a clean area of your hangar, so grit and metal chips won=99t
get
trapped between tire carcass and tube. Baby powder contains oils that will
attack your tubes, Brown Aircraft EC880 silicone powder is a better
choice. Reinstall valve cap right after inflating, so grit doesn=99t
get
into valve causing leaks. New molded seals 154-13000 are superior to oiled
felt washers used on common 5=9D wheels in keeping grit out of bearin
gs.
Upgrade Nitrile caliper piston O-rings to Viton or Fluorosilicone for high
temperature resistance to compression set. Modern wheel weights are no
longer Lead, they are Steel or Zinc and a lot more are needed to balance.
MIL-H-5606 fluid has been superseded by fully compatible far less flammable
MIL-PRF-87257 fluid. Mobil SHC100 is the Parker Hannifin preferred bearing
grease. Use high temperature ceramic grease on anchor pins going into
torque plate.
