I had a lot of trouble with the swing motor bolts coming loose than breaking off, any of the ones i ran never had a swing brake and they where very weak in the swing, Also they would crack where the turn table is welded to the car body, All the hydralics are commercial shear no trouble getting parts for them except the hydralic cylinders think they could be hein werner's own, they used 4 steel piston rings inside in stead of neoprene positive seals. I still run one and it's been a pretty fair machine, i put an Isuzu engine in it about 10 yrs ago though and that was a big improvment over the Gimmy.
