To anyone who has disassembled an Alon nosegear: I had some hydraulic fluid leakage caused by pitting of the plating of the inner cylinder of my Alon's nosegear, so I disassembled it. During the disassembly, a few questions arose because the Service Manuals don't explain and the Parts Manuals pictures are not clear. Can anyone who has seen the insides help with some advice?
(1) The lowest item on the inner rod appears to be a valve. It is mounted to the rod with a bolt and elastic stop nut. It appears that the hole in the rod is elongated to permit the valve to slide up-and-down and uncover a hole; this would provide different fluid flow and action on the up and down strokes. When I disassembled the mechanism, this bolt was very tight, preventing movement of the valve. Am I correct that the bolt only secures the valve and it should move freely? (2) I've elected to not remove the fork from the inner cylinder and to have the cylinder re-plated (yes, it can be done). After soaking in solvent for an hour, the "taxi spring" is still inside the cylinder and doesn't want to come out. Is it fastened inside in some way I can't see? Does the nut on the bottom of the fork just provide a secondary means of holding the fork to the cylinder? (3) In addition to the hydraulic fluid, there was a _lot_ of grease in various parts of the nosegear interior. Was this probably just a means some previous owner used to "fix" the hydraulic fluid leak? Thanks for taking the time to read and answer. This is my first complete annual and it's kinda tough to work on a new machine without some expert guidance. David Alon A-2 #035 N6359V
