These were my photo's, another forum member had theirs fall off is the way I became aware of the issue. Researching the ol' mighty forum I found this very old post regarding the "known" issue. After checking mine and finding the shelf weld was...

Great info. Thanks. I wasn't aware of this problem. Just finished another project this AM (door latch kits), and then put the coach up on ramps/safety blocks to repair leaking fan motors, install a wax capsule controller, and a new floating...

We've a '98 320 and will have this bracket inspected come fall. What is the recommended fix? A reweld? new bracket from FT?, or can existing bracket be bolted to the frame?

Add the gussets and it will be just like the new style.

I'll instruct the service guys to do just that. I'd be chagrined and forlorn without that transmission retarder.

Took a looksee at our accumulator bracket this PM. It has gussets. Not sure if it's a factory replacement, or private "fix", but the horizontal welds on both gussets have stress cracks running the entire length. Dunno if I would have noticed this...

Jack, Bill. I saw your post this morning and checked the coach during the day and although there are no cracks in mine it will be coming off this week for rework. The bracket was only welded on one side and unsupported. Will have more than enough...

Would like some pictures of the failing part. How many miles on your coach?
Scott
I'll post some before and after pics, once I get to repairing it. Just over 100k miles.

Took a couple of pics this AM. As can be seen, the cracks are obvious, the welds are poor (not my first choice of descriptive words), and gussets are puny, compared to what Bill posted.

All the welds visible look shaky at best, the long bead looks distinctly like downhand wirefeed, no bite, no strength.

Greg, mine does not have the webs. Also without removing it feels like the backside is unwelded. Lazy slackers. I think there is enough room to extend the web to the second set of attach bolts on the top side and easily weld the inside 20% on...

The coach won't leave the yard until that is addressed. Thanks for the warning on this problem.

Bill, looking at the third photo it's hardly welded on the front, I would guess that if you were to remove it it should come off very easily, frankly I can't believe it's still there! When I had my fabrication shop if anyone had laid a bead that...

Checked mined today and the weld is OK but I will pull it and do it right.
