When I first got the truck(m1123, 200 amp generator) the stud on the exhaust that holds the rear generator bracket was sheared, and a couple of the front bolts were loose.
It started making noise again, so I checked, and the exhaust stud is sheared again, and at least one of the front bracket bolts has the head popped off of it.
I am not sure what this happened. I torqued everything to spec when I replaced the stud last time.
Anyone have any ideas or seen this happen repeatedly before?
Anyway, I looked up the dimensions of all the bolts and the stud holding the bracket, and have replacement bolts in grade 12.9 on order. Hopefully they take care of the issue so it doesn't happen again.
On a slightly related note, will the overrun clutch for the post 196900 serpentine belt system work in place of the earlier solid pulley on the generator? No idea if it's related to the failure, but I figure taking any stress I can off the mounting bolts can't hurt.
