Hello All. Great site, lots of great info. Early 1990s EX100-2 that is throughly thrashed. But still runs and functions. Working on trying to tighten things up a bit. I’ve searched and cruised the threads but couldn‘t find info on pin bushings for the dipper stick end of the boom. The bushings in the stick are good and tight, pin is good. Bushings in the ears of the boom are gone, departed, nonexistent. I’ve mic’d the bores and they’re still surprisingly round. Will likely require welding and a line bore. The boss for the keeper pin and clip got busted loose and need to be welded back into place. Ive tried to load parts diagrams but have not succeeded. Could someone please hit the Easy Button for me and tell me bushing part numbers? Many thanks in advance!
