Cats have been ceramic coated for years over here. Ive done it also.
I was warned not to coat a ceramic cat tho only metalic ones.
Well i did coat my ceramic cat and it failed after 3,000 kms
Changed to a 100 cell metalic and no issues 6,000 kms and just looked at it last week and no issues.
Looks like its tme for a new Rotrex bracket , one that is solid billet and CNC'ed
But ild look at the auto tensioning ( i believe your engines have it ) . The honda guys here stop the auto tensioning and put a bolt on it to tighten it up or they will have belt slip and or them flying off.
More chances of this happening the longer the belt is thats why ( and by luck ) i only have a short belt, crank pulley , idler and Rotrex
Sorry to butt my nose into this fantastic thread.Found one more weak link apparently - The reason it threw the belt is that the lower S/C bracket cracked right at the end of the little triangulation plate on the corner. Looks as though the far (firewall) end of the bracket needs to be triangulated to the block side. We will post pics and update once we get it removed and some more while we get it re-designed.
Thanks Corky!Sorry to butt my nose into this fantastic thread.
Being the original builder of these mounts I feel obligated to offer as much help as I can in resolving any issues there may be on these parts. I have a full machine shop and am here to help.
Please let me know.
I'll look and see just what I have left over.Thanks Corky!
We don't really need any help per se - we obviously have our own machine shop and welders and all that good stuff. If you have a jig for it and wanted to send an unpainted replacement bracket we could just add the triangulation needed - I will post pics this week to show the location of the crack and the nature of the failure that occured, and what I feel needs to be added to correct it.
Yeah - My first blush reaction was that the gusset could have gone an inch further either way and problem solved since it would be braced past the bolt. But that would make that bolt very hard to install. I'm actually thinking a peice of strap, tube or L from the bottom at the end (forward most point) back to the point furthest back where it bolts to the block. Or both.From an outside perspective.
Looks like material fatigue.
The gusset ends at a point where there isn't any support, seems like it could extend down toward the screw hole a little further.
No worries - I appreciate the interest and intent. We will get it fixed up or just build a new one.I have gone thru most of my old Rotrex stuff, and I have nothing left that would be of any help.
I had some bending jigs, and a welding fixture that might have helped out, guess I need to be present and oversee spring cleanings around here.
They welded in a large triangular brace along the bottom and built a new upper.What was the out come of the SC bracket ?
Did you make a new one or just reweld it ?
