Guys I have a hitachi zx50u and I have a few specific questions. the quick coupler needs a bit of work, (round bucket engagement ears worn and rear wedge area cracked) I may have it repaired but i want to look for a good used one. I know the machine is the same as a Deere 50zts, does anyone know if the coupler from the deere 50d, or deere 50g will interchange? How about a deere 60? Also, I am looking into replacing some pins and bushings. I have almost everything apart, my question is, what is the correct amount of air gap between a pin and bushing? I want to do the swing post, and the pins are definitely worn. I cant tell if the bushings are worn or not though. Any advice will be appreciated.
If you can see pin moving back and forth then you probably need new bushings only way to be 100% sure is take it apart and measure it
Hard to tell because the pins are so worn. I don't mind replacing the boom bushings, however the swing tower bushings look like they may be hard to remove. I have the pins out and the swing tower separated from the excavator frame. The large swing tower pins are definitely worn
If pins are worn that bad bushings have to be worn . Call dealer and get specs for pins. and bushings . Measure bore with set of these if you want
