Lubricating TL Lathe Z Ball Nut

athack · May 9, 2014

Okay.... I'm sick of getting on my knees and jogging the Z axis until my grease gun fits between the frame members to lube the Z Ball Nut. :willy_nilly:

Has anyone come with a better way to lube the dam thing?

Please help!

Thanks Athack

watching this with interest!
Very bad accesability.

OK..I removed the zerk and was going to put an extended grease line on it.
But I found that the zerk appeared to be a metric thread. :angry:

Not wanting to screw up the threads in the nut or bastardize it, I made an adapter fitting from that thread to 1/8” NPT.
Then I ran a grease line up to a bracket on the back of the guard that travels with the carriage.
Now I can grease it while standing behind the machine.

I will try to post a picture when I go back to work next week.

Nice improvement. Yes, that zerk IS hard to reach.
Next time I see the hydraulics guy, I'll give him an order.

I just used a standard long grease gun hose. I welded a 1/8"NPT pipe coupling to my bracket and adapted from the zerk threads to NPT on the nut end. Nothing special accept for the little adapter that threads into the nut!
