I am about to undertake an overhaul of my MLG due to play at the knee joint. I will be pulling the entire gear to inspect it and replace the needed parts. So some ques4tons. 1. What causes the excessive play in the knee joint. Is it mainly a worn knee joint bushing, or the washers, or both? I would guess BOTH, since you are referring to exessive play. 2. The kneew pin, the one that costs 250 bucks a pop--do they have to be replaced, or can you usually get away with new lockwashers and nuts? It depends on the pin that you have. If it is pitted from corrosion and worn, you better replace that. Better to loose $250 now, then 10000 later when you groundloop. 3. How tight does the knee pin nut have to be? Just tight, dont clamp the gear together, especially when it is from forged aluminum. 4. How does one remove the knee joint pin without damaging the threads? Open safty washer behind the nut and unscrew nuts. 5. What are the bolts that hold the leg to the spar...the ones with allen heads? I can find no reference to them in the parts manual. No idea. May John from Skyport knows 6. I have already added the collar to raise the tail, but any other tips would be appreciated. A different taxi spring in the nose gear would bring the tail up too. There used to be a shorter one for the 6inch nose wheel installation. I don't know if that would be still available. If so. I want one too. Thanks Steve Finkelman C-Fiwr Forney F1
