I've been following this thread with interest for a while, as I'm on the point of buying one of these lathes. But all of these reports of oil leaks are dampening my fervour!

I wonder if this is true of all GH600s, or have you guys been particularly unlucky? Judging by your investigations, it looks like there's a design fault somewhere.

Anyway, please keep posting. All the best.

Most of these lathes have grown out of older western designs from back when a bit of oil leaking was not a problem.

Centecs for example have one proper shaft oil seal on the 3 shaft gearbox and none in the vertical head so they weep and make a mess.

It would be a mistake to bin off a lathe that clearly suits your needs, space and pocket and pick another that may have unknown issues till you get it home.

Better the devil you know

Iv had my GH600 since January, it’s used daily and it does leak oil. I have only topped up the oil up twice since January so it’s not a huge problem.

Tboy did send me his write up on solving the leak, I intend to do this when I have time.

cheers

What oil are you using Lee? I think I'm just going to buy some from Warco, but I'm open to other suggestions

Hello Dave

The silly issues are a pain in the whatsit but if it was too much to bear and if most of us weren't engineers and enjoy a challenge, I'd probably would have returned it.

However, it is a good lathe as far as I know and enjoy it too much to allow it to be anything more than a minor "challenge" here and there. smiley

The Warco oil is most likely to be an ISO32 or an ISO68 industrial gear oil.

I would say that the lead screw gearbox may engage gear slightly better with the ISO68 oil as one of the shafts is free to spin when the gears are in between engagement - this can make its slightly more tricky to get it engaged as when you turn the chuck to giggle things about the free shaft turns with it just from the side force friction between the gears and the teeth stay miss-aligned. A little extra drag from oil would do no harm at improving this. I probably haven't described that well and I'm not suggesting any fault with the way it is - a little bit of a experience and you get the hang of changing the gears.

The main gearbox on my machine seems to drag a little when cold if you use the high speeds (1500/2000). Be interesting how it run with ISO32.

Grizzly do spec oil in their manuals and recommend ISO32 in the main gearbox and ISO68 in the lead screw gearbox on their smaller GH machines.

Any recommendation for lead screw lubrication? I have thoroughly cleaned mine and from the factory it was well plastered in red grease around the half nut area. Is red grease a good lubrication for the half nut and worm gear?

I would normally have chosen on oil for the lead screw but i am a little unsure with the worm gear.

Jed,

I am using shell tellus 32. I buy this in 20 litre drums for my day to day work anyway.

some recommend 68 oil in gear head and 32 in apron etc. I just use 32 for everything. Keep it simple.

thanks

Jed, Daniel, Dave, Brian, Lee, TriumphBoy, thanks for sharing your views and experience. Yes, the GH600 seems to suit all my needs much better than anything else I've seen. My fervour is re-ignited!

Hopefully I'll be able to share in this thread soon as an owner - will let you know,

All the best

Hi All, New guy here.

Thanks for all the valuable info in this thread.

I'm wondering if one of you GH600 owners could give me a height measurement from the machine, drip tray to switch gear as I have a space on my workbench which has a 580mm height clearance between the bench top and the cupboards above and I want to know it it will fit.

Many thanks.

Steve

Hi Steve.

Distance from drip tray to top of switch gear is 500mm .

I used the Warco headstock oil for everything when I changed the oil .
