Larry:
thanks for the detailed report on your nose gear failure.
I'll go check those parts on my 235 BEFORE my next annual,
which is only a month away.
The phenolic block and roll pin sounds like a
good solution to the problem of shaft rotation
Some may have heard my 'solution' previously but here goes: During my 235 BF [built before fastbuild was heard of] I had read/heard about a number of nose gear problems. I decided to try to invent a possible 'helper' system to get the nose gear extended without hydraulics or 'spring strut'. I installed a bushing in the nose gear tunnel on each end of the rod [being discussed], roll pined the gear weldment to the rod, placed a pulley [as large a diameter as possible]on one end with a cable around it that could be 'winched' using a 1/4 drive extension and an appropriate ratchet operated by reaching down near my feet with my hands. Two ratchets are used: one on each end so that pulling up on one tightens the cable and the other ratchet keeps the tension while getting another 'hitch'. The 1/4 extensions are supported by two pillow blocks [phenolic construction] fastened to the forward face of the front spar with the appropriate adhesive/glass layups and about two inches above the floor panel.
Turning that rod attached to the weldment causes the overcenter link to [hopefully] extend the nose wheel assembly and then lock it in place. Does it work? Hmmm, hope I never find out... so far haven't needed it.
At least I don't have to worry about the grease/wearing etc with this method.. and that wasn't even considered then. Good luck! Earl
