I have just gone to change the quick change lift arm balls on my MF35 from cat1 to cat 2 and it has not been quick. Turns out that two quick change cat 2 balls purchsed with the quick change lift arms from the same supplier are not the same size. The difference is about a millimitre or so on the outside diameter. One fits perfectly (56mm od) and one will not fit (57mm od). I've looked at parts online and all the ones I can see that look the same are listed as 57mm od. The cat 1 balls I just removed to put the cat 2 balls in both measure a smidgen over 56mm and fit just fine. Can't take the angle grinder to it or I'll make it uneven and end up with something very much not round. Anyone had this problem? Have tried my local Ernest Does and Ben Burgess in Norfolk who both said they had such a thing and then didn't when I turned up. The supplier who sent me the first lot measured the ones in his store at 56.4mm. I wanted to move a bit of machinery asap so I think I probably have to sit there with sandpaper until it fits. Any faster ideas?
