Got a problem with one side of lowers on said fork. Changed car year ago to one without towbar so have been putting bike in car, and removing wheels to do so. Front of fork by axle has 2 forward pointing bolts going into a crossways pin to pinch axle. one set per leg – make sense?

Last week noticed is crack in metal around the crossways pin and radiating out, one leg only. Mojo say is torque set bolts so no warranty, fair enough I don’t carry torque wrench but surely a ruff tough fork should be better designed? Also I am aware of being not the only person with this issue.

So question is, repairable or new lowers? I was thinking try local engineer/ frame builder, see if can weld/ put some sort of sleeve in place to repair?

Cheers in advance, sorry long winded explanation.

Early 36s did this, a washer exists to stop overtightening.

No repair AFAIK, no idea what happens if you keep going either. Sorry!

well known issue, no fix apart from hugely expensive new lowers or a scrap pair off ebay

Cheers, confirmed my suspicions 😥 guess I’ll be ordering some new lowers come pay day. Better make sure that washer is on the new lowers.

New forks and hence replacement lowers will be different castings AFAIK.

Depending on state of foks may not be most economic.

Quite a few of the lowers did this, produced shims to stop the gap in the fork closing too much.
Quite a few people still ride with cracks, however I wouldn’t recommend it Drop me a mail if you decide to replace the lowers as I can supply these 😉

It’s quite infuriating that is well known design flaw, probably why changed design now, and they don’t do anything about it. Even to offer a slightly discounted lower replacement would engender good will, yes I accept some responsibility for over tightening but if is known fault they should share liability.
With my mass and riding style not even going to chance it, putting my old Dukes back on the stiffee until resolve. May look into repair but could be in contact for lowers cheers LoCo.

No Problems, quite a few of lowers were replaced at service time when the forks were new, the torque is v.low 4Nm I think, keep us posted with the results if you do give them to a welder, maybe of interest to some others on here.

will do, just need find local welder now.

dude get your lowers from loco, I saved a packet with my 32 lowers, Simons a top bloke.

SSHHH! 😉

I don’t think magnesium welds so well?

That’s what reckon too but will check with a welder if find one. If decide to replace lowers will be in touch Simon, rather give business to somebody from here.

I’d have thought a more likely fix would be with say epoxy and a plate of metal with a rectangular hole the right size to fit over the casting and stop it enlarging/cracking further.

Mind you I can’t remember in detail what it looks like. Mine have the washers.

It is possible to weld, Dymag the motorcycle wheel people used to be able to repair their Mag wheels. Specialist and possibly exspensive, not something I’ve had done myself so couldn’t say catagorically as to whether the lowers are weldable.

Just spoke with my mate, a blacksmith, who says will probably cost more than the replacement lowers. That’s if I can even find somebody local to do it. Apparently quite complex involving shielding gasses and other such complex sounding things.
Now just to convince the wife, who’s offered new lowers as my Christmas present, that it is actually being held in October this year 🙂

I’d have thought the tiny amount of metal there would have been a problem too. Good luck NSN

could you hire a few local tramps to sing carols outside your house?

I like you thinking, maybe convince some trick or treaters to sing instead.
