Can anyone possibly help me with the proper carrier bearing# for these extension boxes. I am restoring a 1999 34 Sutphen and it has Stelling boxes. When I pressed apart the carrier I found two thin bearings and I don't feel this is correct. Any insight will be appreciated.

Thanks,

Hey guys one more question, I am going to be reinstalling the carrier bearings and was wondering about the hardware that I should be using. When I took these apart it was a grade 5 rusty bolts. I would like to know if I should use grade 5 or 8 to hold the carrier in place. I would like to replace with stainless but want to know if stainless would be strong enough to work for this application.

Thanks,

Anthony

See what other guys say but if you have that much water in the box you have other major issues. Stainless shouldnt be needed.

I used grade 8 bolts, welded a 3in long piece of 1x1 angle to the head so they can be tightened without a wrench ont he other end and painted them from the threads down just in case their is water intrusion. Used red and tacky Johnson grease on the threads. I also put about 1 inch of some silicone on the bolt shaft. If you bolt the carrier in and let it sit overnight you can come back the next day and fool around with different shims and not lose the bolts after disassembly... (if necessary)
