Lock stop broke off.

[WmY]

Light alloy bottom yoke has two protuding lugs incorporated into the casting acting as steering lock stops.

Unfortunately, one has broken off flush with the surface of the top of the bottom yoke.

Is welding a possibility? Non-original material would have to be built up with weld or welded on.

(After all, the alloy was molten at casting time, although I'm uncertain of what the alloy actually is, and the effects of heat and time on its metallurgical properties).

Edit: As things stand, it seems to be an MOT failure.

I had a lug break off one of mine about tens years ago after it fell over.
As it was my only transport at the time I didn't have time to change it, so My solution was to drill a hole in place of the original and tap a bolt in.

I still have the bike today and the bolt is still in place and doing it's job just fine

Since when has a non working steering lock been a m.o.t. failure?

What bike?
( why do people not say what sodding bike?)
I reckon you could
TIG weld
Aforementioned drill & stud
Sleeve with pokey out bits ( technical term)
or Just burn it and send it hell
and yes of course it's an MOT failure

It's very common to break the lock-stop when someone steals a bike by percussively breaking the steering lock and is why I never use such things.

Have you priced up a used replacement bottom yoke? May not be as much as you'd imagine.

Look on the bright side.

You've a great chance to out-odd jaffa90's 45 odd years of riding by simply turning the 'bars 180° and riding the bike backwards!

Don't forget to cross your arms, though, otherwise -- what with the controls being all arse-about-face -- things might get a tad confusing, if not somewhat dangerous.

Hey! No more need for shoulder checks!

MOT rules basically say that the handlebars shouldn't touch anything or trap fingers at the extremes of steering; lock-stops should limit travel to prevent this.

Common for stops to get broken on theft attempts or when bike dropped....

On which basis, I would be more concerned WHY the lock-stop's broke, to begin with, than wangling it through an MOT... it may be the least of your worries if the frame or forks are bent from a drop, or the twockers come back.....

What bike though would definitely help with fix suggestions; different bikes have differnt lock-stop arrangements... may be possible to add something to the other mating lock-stop on the frame, to limit travel both ways;

Personally, I wouldn't even dream of trying to re-make lugg on bottom yoke.

It could be done with aly braze suych as lumiweld, or MIG, but the amount of metal I would imagine would need laying on, be easier to weld something, like a bolt in place than build that amount of metal up in weld...

Then given burning out the headrace bearing grease, and probability of burning wiring looms going throuygh that area? It would be something I WOULDN'T tackle with the broken yoke still on the bike....

Given you would have to take off the broken yoke... why not just replace it with one from a breakers or brand new! Its probably just as onerouse and no more expensive than taking the chance on welding or brazing.

To do in situe, and save taking apart or buying new bits.... I rather like my tap and die set... so drilling to take an M8 and tapping the hole tight would, likely be my preferred method of salvage.

But depends on what bike, and how much guff is around the yoke, and how hard it is to come by a new one, and how expensive etc....

Tell us the bike!

Easy fix, a block held on with a bolt

I'd just drill down into the hole where it broke off, tap it and fit a socket head cap screw in there with loctite (probably an M6). The head of the capscrew should act as a lockstop. Use a good quality mild steel one, not stainless.

If the hole goes all the way through (tricky to see on the pictures) then a nylok nut on the back of it.
