Hello new member here. Curious if anyone knows the bolt size to remove counterweight on a Hitachi EX50URG? I’ve seen some old posts about them so I know they’re out there. It’s 2-41mm bolts holding the weight on. Thanks Mike
Good day Mike Not sure if this helps. Kind regards Uffex
Interesting. I had no idea that M41 existed. That’s an oddball, for sure.
I 'spect its a 30mm bolt. Dam metric system can't decide what size head a bolt should have. Standardized my ***.
I got the counter weight off tgd Ex50urg, pretty easy with the right tools. I was hoping the leak would be obvious but no such luck. I have to get a closer look at the swivel joint and the swing motor. Previous owner rebuilt the swivel joint. Hoping maybe a hose backed out. Anyone know if the swing motor is accessible from below or do I have to separate the unit?
41mm socket on attachment bolts. Lifting lugs are M27x3, I had to purchase a tap to clean them up to thread in the lifting lugs. Sorry for the confusion.
Gotcha.
Pic below Is from Spare.AVSPart.com Swing motor and or swing drive are definitely NOT accessible from below. For future reference only, the Swing motor and drive (complete) part is # 4243574 .
