MG Midget and Sprite Technical - Laygear condition

I probably should have expected it based on the condition of the layshaft, but I'm guessing my laygear does not look good.

I was hoping I'd get lucky.

Hard to see the condition in the photo, but I'm assuming it's badly worn.

I was recently wondering how feasible it would be to sleeve the inside of the laygear. It would be a shame to scrap one which didn't have any damaged teeth.

As Dave suggests, could you post a clearer picture of the inside of the laygear plus a picture of its gears.
Bill Bretherton

A clearer picture or two would be good but from that pic it looks like the ends of the rollers have attacked the step in the cluster
If the actual surface where the rollers run is still ok, fitting a hardened thrust washer in there to give the rollers something smooth to work on would save the cluster
Last choice--fit a bush in there,

I'll post some pictures I have, and can try to get better ones tonight or tomorrow. I'd really like to save this if the gears are good.

Thank you for the responses. I'll post three more pictures, hope they capture what needs to be seen.

Second of three.

And the external view. I can get a lot better detail if it would help.

Thank you.

The wear is usually on the first gear teeth and from I can see from the photo it looks in reasonable condition. The bearing surfaces for the needle rollers bearing however look in very poor condition and will need renovation. It may be cost effective to have the laygear sleeved as Dave has suggested. You can of course purchase new a laygear from the usual suppliers.
Bob Beaumont

Yes, the gears look ok so it's a pity about the bearing surface. If you put new needle rollers in they'll probably be noisy and wear will continue. Sleeving may be an option but might cost more than a new laygear. You may get lucky and acquire a NOS laygear in the US. I think there is a variety of quality in replacement parts.
Bill Bretherton

Sorry for the silence. Family health issues have kept me out of the garage.

My plan is to look hard at the option of saving this laygear, but I have the feeling the option of restoring the bearing surface will get me close to the cost of a laygear. And that might get me close to the cost of a rebuilt unit (kind of).

It's a long weekend here and a rainy Monday is coming, so I hope to make progress then.

I'm curious: the usual sources here in the U.S. pretty much means Moss, or VB, but are there specialists? There are so many transmission repair businesses in my area, I wonder if I make a lot of phone calls in ever-widening circles I might find someone with a good used laygear just gathering dust.

I just searched on eBay.com for 22G1100 and it came up with a couple of used options - although it's difficult to see how much wear is present, from the photos - plus a job lot of NOS parts, which looks like it includes 3x laygears.

If I lived closer to California, I'd be rushing to buy them.
