Early on I switched out all bolts that are used as hinges in aluminum linkages with close tolerance bolts(AN173-AN183 series). These are held to right around .001 undersize. Your typical 1/4" bolt will run .002-.003 and can be as bad as .004 undersize. Switching bolts plus annual disassembly, cleaning and greasing has prevented propagation of wear. The bolt that attaches to the nose gear gets replaced every few years. The metal tangs will wear groves in the bolt over time if left unattended, even if a close tolerance bolt is used - more surface area is needed
on those tangs. By periodically replacing this bolt, the two pieces will tend not to chew each other up. This is not an ideal solution but it has worked well for nine years and 1000+ hours. Hopefully your excessive wear in only 100 hours is an anomaly. A redesign of this joint would certainly ease the maintenance burden and could guarantee a better fit right from the start. Keep us posted on your findings. Chris
