Anyone think any of the three of these are salvageable?

No. 1







No. 2







No. 3

Seen too many of these snap, they are 40+ years old and modern metal is stronger. AF is punting Italian ones or better still MB, expensive but wot price can you put on piece of mind?

1 yes
2 no
3 yes

As long as the threads, teeth and bearing surfaces are good they are pretty durable. I'd spend some time cleaning them up with a stainless brush by hand. From there you can get a good look at whats going on. Also measure the end plate shaft diameter between them all to see what kind of wear they might have.

^ Agree. Due to the splines, No.2 is a scrapper: something bad has happened to this in it's past, so I wouldn't trust it. No.1 and No.3 look ok, but being safety-critical I would clean them thoroughly before giving them a real good looking at. Check endplate end in a new needle roller bearing in a known good endplate bearing outer race.

None of those bearing surfaces look any good (where the needle roller in endplate will run) as soon as the rust pits it the bearing surface is fooked. I fitted bearings for a living for 3 years and those surfaces are knackered. Bin em and be safe. Not worth the risk or the time of fitting and then taking out.

rusterstions am the fashion; start fom inside and work out til y get t ya paint; bita scotch brite then Brillo t angle grinda; job dun I got sum rusty berings y can ave;

really they all look knackered t me
muppet,

the consequences of failure are too high to take the risk with any of them without serious ND testing, the cost of which would be more than the most expensive replacement layshaft, scrap em mate

I'd go with Grumy's choice. The design seems pretty robust to me. I'm sure some are braking due to over zealous tightening if the hub nut IMO. I also think hard rear end suspension and heavy weight don't help.

Maybe they never envisaged 30 stone of riders plus luggage when they designed them.

All 3 scrap
