Hi gang. I have an older 331 (1999ish). The other day i heard a crunch and then lost all swing ability. Having replaced the swing motor years ago I assumed that the gears had all broken off. I tore it all apart yesterday and found a much bigger problem. All 8 of the bolts that hold the carrier to the machine were broken or stripped out. Clearly it had been like this for awhile. Replacing the housing and replacing seals and bearing while it is apart is just time and money. My bigger concern is how do I best fix the actual frame? Drill out and rethread with larger bolts? through bolt? Has anyone dealt with this before? Anyone in upstate NY want a project?? Thanks in advance for any and all help!
