Few pictures of my Gear box shafts can you let me know if they are keeper or not thanks

Lay shaft








Reverse Shaft



Main Shaft







Thanks

Mainshaft looks ok,

layshaft, the important bit is the bearing surface, maybe clean it up with a bit of fine emery as hard to tell with the crud.

Edit, as long as there's not pitting or corrosion on all bearings surfaces you should be fine if they clean up.

Lay shaft its shelf has a small lip on pics 1 4 and 5 looks like a bearing has got hot on it at somepoint

its a 60,000 mile box as well

Layshaft needs replacing, reverse shaft may be ok. Mainshaft looks ok on the centre bearings, but couldn't really see what the 1st motion needle roller face looks like on the end...looks a bit blackened?

Think its dirty on the main shaft, Oil in the box was like treacle

I'll dig the mint reverse shaft i binned earlier incase yours doesnt clean up.

Nice one dude Ill clean it tomorrow

GT85 and wire wool do the job?

Your better off with thinners/brake cleaner and scotchbrite.

Been told Main shaft Roller bearing faces are pitted meaning thats a gonner to?

Pitted= gonner

You haven't taken a picture of the most important bit on the main shaft. The little end inside the 1st motion shaft. Looks rough. Looks scrap.

Want me to go get a picture?

Few more pictures

I got a used good mainshaft of guessworks. If that helps.

Just had a look on his site he's got a few in stock so gonna order one Friday

on the topic sort of..

to check for surface hardness where is the best place? clearly not where a bearing runs. .
middle? end?
asking as ill be using new main and lay and dont want the hassle of a shit one

already had problems with it not being ground to size it had a taper on the bearing surfaces !!

Not sure if it's only discolouring, but if it's pitted, even the slightest bit, it's scrap.

Main shaft is a deaden so is the 1st motion gear and bearing :/ seriously

300 quid mini turning into a... watch this space haha
