My Ercoupe Service Manual (Univair PN 004-00001K) states on P40 "With strut extended, fill it up to red line on gage; it should take about 1 1/2 pints of fluid. In static position, fluid is at green mark."
Don't know about Alon, but 7 to 11 inches corresponds somewhat to where gage marks are in my description.

The Alon Maintenance Manual says nothing about a gauge, only to "fill to its working limit" 'it will take approximately 1 1/2 pints.' {My filler plug showed no signs of a gauge.) After reading your e-mail advice I went back to the hangar and read every piece of service advice I had. The only reference I could find was in "Fornaire S/B 113" which also said to 'fill to its working limit' plus in a note said '7 to 11 inches below the top surface of the filler plug hole.' I assume that this is with the strut extended. Having seen the inside of the strut, I now understand that this would assure that at its lowest level, fluid would cover the piston valving. I guess I'll include the level check at my next annual by inserting a small diameter dowel down there to check fluid level. ==================================================================== David Abrams wrote: > > In the middle of the top of the front fork is a square filler plug.
