Per Alon service manual "the shock struts has 7 Belleville Taxi springs." It goes on to say "The strut should be filled in its fully extended position with the rubber bumper removed. Approximately 10 ounces of hydraulic fluid is required. The fluid level in the strut should always be checked with the strut fully extended position, and the level of the hydraulic fluid should be up to the filler opening. Lack of fluid in the shock strut may result in serious damage to the center section on hard landings. The Taxi spring need no service other than periodic inspection."
To me it is saying the fluid level is important. And the donuts are for
taxiing.
I started to look into why, or put better, how did Alon with a 5 inch
nose
wheel keep the tail up?
Alon used the same nose strut cylinder & fork as late Forneys. The main
legs are the same. Both came with that fork now sold by Univair, is the
Ercoupe nose strut different? Don't have an Ercoupe part book here. Found
three different nose struts in Univair. Steel scissors # 34080 # 34130
also
steel #34305 ser # 5675 and later That would be in 1959 F-1 Forney. Looks
like I am missing 1947 CD &D Electrol nose strut? {Or it may be #34130}
Anybody know if there is a difference in how long the struts are? How
much
if there is?
Spacers may be a fix, but how good is it if you may cause damage to your
carrie through spar?
OK, how about all the Coupe landing everyday with dry struts? What
damage
is being done?
Just more to think about. Warren H.
