Snapped Pillion Footpeg subframe - repairable?

[retroman]

I was reversing my 2002 R1150GS out of a garage on a recent tour when the offside/RH footpeg caught on the door frame, causing the subframe that holds the pillion peg to snap (don't ask me how I managed it, sheer stupidity I 'spose)

The replacement part is about £140 .....

It is cast metal and I'm wondering if it can be weld-repaired ... seems like a clean break if that makes any difference.



Advice welcome ....

Should be weldable if the whole thing is up to temperature, ask a local welder for advice.

Yes that's my next stop, I know nothing about metallurgy, I'm hoping that its fixable. It dosen't have to be pretty, either!!

Did similar on K75 22 years ago, had it welded up from the rear of the hanger, still on bike now. You can see it's been welded if you look but doesn't show much. Should be no problem for a competent welder to sort that out for you.

If not, give me a shout, I have one spare but my plan was to put both on Ebay as a set, complete with the pegs and pivots

Thanks chaps. I love this site, never lets me down!! I'm hoping that a welder can sort this rather than buying a new part. Even Motorworks are quoting £40+ for a 2nd hand part from a scrapper. Fanum, will get back to you if need be... !!

sounds like a no brainer to me, spend the money or risk losing your pillions leg? cast aluminium welding will probably cost more than £40 unless you can find someone to do a cash job and even then can you trust it?

Eh???? That's why I asked the feckin' question, if I can get the part safely repaired then fair enough, if it's not viable then I'll get a new part. I'd never put my pillion at risk, FFS!!

no need to get miffed old boy, just how where you going to get it repaired and tested for less than a second hand part was my point ?

Welding by a professional will be as good as new but will cost.
Looks like Fanny may be keen to sell you something.
PM him for cost is what I would do.

Aye, I think that could be a plan ....

Epilogue -- spoke to a few welders who weren't happy about doing the job due to the location of the break. So repair ruled out.

Those good folks at Motorworks have sourced a S/H carrier for £45. So it's en route.

Thanks for the input / advice.

I've had various cast aluminium parts welded. Done properly will be plenty strong enough but unless it's jigged the parts will not be fully in line. Any bolt holes in the welded area will need to be drilled out.
The original part probably broke because castings can be brittle especially at changes in thickness. At least this broke on impact rather than bending the frame mounts.
TIG welding would repair that but if the parent metal spits and gasses the weld might not be successful.
I've seen a VW Beetle gearbox mounting lug repaired with Lumiweld which did the job fine. That's more like soldering than welding so less likely to gas the metal.
Even if you can DIY, a new used part is likely to be cheaper cost.

Thanks for that. Useful info.
The new part has arrived, it was a five minute job to swap over. £45 from Motorworks. Quite a pricey mistake on my part, but these things happen.

Cheers chaps.

Welding would cost at least that.Lumiweld rods are £20 (Iirc). You'd then have to file the crack face smooth and hope the stuff doesn't just run out like water.
It's great when it works but easy to scrap the job before you start.
