PM 90 users what to lubricate

[William C Rogers]

I have a PM 90 in great shape. I regularly oil the hole in the head. What I was wondering what else should I lubricate? Should I remove the handle and lube those parts. What is best to use, dry spray, oil, or grease?

The oiler in the top will Lubricate everything in the headstock that needs it. I had to lube the lower pulley spring assembly once because it wouldn't open all the way and it would slip after 2500 rpm. I just used silicone spray. Also, check the tailstock lead screw threads. I used bearing grease for that.

Thanks Gordon, I didn't see anything in the old manuals and was wondering if that there was a service manual that described more. I had the handle off about 6 months ago when I raised it 3" and everything inside looked to be in good shape. I'm waiting till I wear it out before I buy a new lathe.
