Dealer mess up
- Thread starter MaxTunk
- Start date
I am a specialist welder of over 30 years experience. I hold certificates for pressure vessel work in steel and aluminium. Welded properly your swingarm will be no worse off strength wise but finding the right guy with enough experience may be the challenge.
ttpete... Heat treatment on aluminium is never gone forever, it simply needs re-setting at the right heat for the correct amount of time. Aluminium can be repeatedly annealed and tempered with no ill effects IF done CORRECTLY! I agree with you however if they had heated it as described in workshop manual proceedures there would have been no problems at all.
Like everyone else here though, I agree the dealer is obliged to replace your swingarm with an undamaged unit, even if it is second hand. Although it is Possible (but perhaps not entirely practical) to repair it correctly I myself certainly would not want a patched up item back in exchange for the good one I sent to the dealer.
My dealer damaged the steering ringnut and scratched my upper triple at the 1000k service and denied it. It took me 3 months but in the end they had to replace it so stick to your guns mate. I wish you luck with the 'negotiations'.

Then again , there might be a sign stating.. All care but no responsibility..
Did they even HINT that the bearing might be a pain to remove? that there was the SLIGHTEST risk it might have corroded and frozen in there?
You're more likely to receive an equally second hand unit as your, I believe, was not a new one..

True enough, but to do that, you have to know what the alloy is to begin with, and then know what level it's taken to - T-4, T-6, T-?? By the time it's welded, machined, heat treated and zyglo inspected, it'd be more economical to find a good intact used part.
If I owned the business, I wouldn't touch the repair with a ten foot pole, just for liability reasons. It's a critical part of the suspension.

It arrives back from the welder tomorrow. If its not perfect, i will not accept anything less than a replacement. Then, if it IS perfect, i'll make sure they agree to replace the bearings just in case there ends up being some deformity of the metal after welding and it cracks when pressing the bearings back in.
Thanks for the motivation, guys! I'm kind of a push over with this kind of stuff and honestly didnt want to piss off the only Ducati shop within 70 miles of my home.
Will let ya'll know how it goes tomorrow.

Some bearings require freezing or heating to get them in and/or out - eg: press fit/interference fit...
Although this may not be common with motorcycles, the workshop should have known about this and not forced the bearing out.
A buddy of mine had to put one of his triple clamps in the fridge to get a bearing out.
Personally, I would accept no less than a replacement swingarm.
Do some research and you will find out how complicated the welding is for the swingarm on these bikes.
Eg: The weld mark on the left hand side is actually to close a hole in the swingarm, that they used to weld the extruded sheets to the cast swingarm pivot and wheel mounts from the inside. The Ducati arm is a work of art.
The only way I would accept a repaired swingarm is if they compensated me for it and got a certified welder to weld it according to Ducati's weld procedure and specifications.
I'm quite sure that your swingarm aint gonna be 100% straight after this.
