JB Weld on Chain Adjuster?

I recently replaced my rear chain adjuster because the bolt came off of it. I guess I didn't tighten up the axle enough because the axle tilted and sheared off the bolt again.

I really can't afford to buy another adjuster right now, would it be feasible to JB Weld the bolt back onto the adjuster part?

If light tension broke the bolt, don't expect any miracles with JB Weld.

I tried JB Weld on a broken windshield mount and it failed. I would never trust it for something more integral like rear axle alignment.

The adjusters are just that, not intended to be under tension solely intended to help with set up of chain tension and alignment. These tasks can be accomplished without the little jack screws just not as easily. Get it lined up the best you can and make sure of your axle nut torque. IMHO futzing around with JB epoxy glue (No welding involved) would be a waste of time.

I think "A waste of your time" would be a great slogan for JB Weld.

:whistling:
for this application, perhaps... but, not always.

I had a coolant leak in my old Escort, and what they found was that a frost plug had blown out of the aluminum block in which the thermostat mounts. (why these frost plugs, or more to the point, the holes they plugged, were in this block is still in question...)...

anyway, the local auto parts store does not have the correct size freeze plug in stock (it's some wacky non-standard size, too, apparently), but Ford will gladly sell me a replacement block of aluminum, presumably with the correct freeze plugs installed, for only $380. If the engine were running without spewing all its coolant through an almost 1/2" hole, the car might be worth $380... I'm thinking I don't want to spend that kind of money for a repair. Oh, I should also point out another inconsistency in the Ford labor manual -- it states this is a 4-hour job, at $75/hr. Just for grins, I had him look up in the book for the labor on replacing the thermostat -- that's a half-hour job, at $75/hr. (for those imagining this in their mind, the thermostat attaches to the block in question here, and the labor to do either task is exactly the same!!)

Anyway.. the guy recommends I find an appropriate-sized steel bolt and let it cut its own threads into the aluminum block as it's screwed in, then coat the whole mess with JB Weld. Short-cut to the end of the story: worked like a charm, never had another inch of trouble with the cooling system in that vehicle, and the total cost of repair [including plenty of leftover JB Weld] was $1.87+tax.

Are you talking about this piece/bolt?

If so, go to a hardware store, buy a bolt of similar size - a little longer though- and replace it. To replace it: Hack saw the bolt head off, stick it through the hole and use nuts to secure it. You could use Locktite or JB weld to secure it if you like...

If I am misunderstanding the problem let me know.

I wonder if I'm just mixing it wrong or what, but I've had nothing but failures from JB Weld.
Tried to fix the crankshaft hole for the locating dowel, failed.
Tried to reconnect the headlight to the mount that broke off, failed.
Tried to repair a cabinet door hinge, failed.

Always had way better luck with Quiksteel. Maybe not for vital parts, but it got the job done when I needed it to.

Maybe one day it'll work for me...

Try using it with fiberglass tape I usually use double. stagger it of course.

I imagine for "something that fits INTO something" it would work, but for "something that fits ONTO something" applications I won't hesitate to use something else.
