Updating oil in a lathe headstock

[cocker]

If you are running the machine please tighten the jaws of the chuck on something .
If they're not tight they can work there way out , then fly !

Oh - I've just got this! Sorry

Any further problems just try switching it off and on again!

I'm thinking of doing mine too, it's a Chester Centurion lathe with a basic gearbox. I've got some gearbox oil for 2 stroke motorcycle gearboxes, will this be ok?
Not sure if it's ok with yellow metals or if I've even got yellow metals in my gearbox!
Cheers for any advice.

The answers are all further up ^^^^

I went with ISO32 - there's a link further up to 4.5L for £15 delivered.

Looks like a bit of sloshing some diesel around may be a good idea once the goop is out. Then I'll flush the diesel again with some of the new oil.

A kerosene/paraffin or diesel wash is a good idea. It'll loosen/soften any gunge in there. They're about the best non detrimental cleaner/degreaser you'll find. I use a fair bit of kerosene, (heating oil), cleaning up my stuff.

Cheers Matt. It looks like it needs a decent slosh and it will hopefully dilute any of the cruddy thick oil left in there.

That's boxing day sorted

The good thing about spalsh-fed headstocks is that once crud has fallen out of suspension it'll likely never move again. Given that most lathes spend a long time turned off that gives it a good time to settle out.
