I went to paint the headstock casing yesterday and noticed a worn area. I think it's where the quill rests and spins. This will be my first attempt to attach a picture, so I hope it works, and I hope someone has some good news for me. I guess i need to know if anyone thinks that the casing is still good to use. Thanks again in advance.

Since yer Greenie has a low SN, I assume it may be a sandcast headstock. If it has two tiny holes on the quill STOP side, it is an early sandcast headstock. These are much rougher in finish and precision than later die cast headstocks. They are also thicker!
The area you are concerned about is not intentionally a bearing surface. It IS possible that the quill feed pinion gear has been rubbing there at some point in time. If it is still rubbing, I would file down the casting until it no longer rubbed.
The actual bearing are out toward the end of the quill feed shaft. The quill feed shaft should be reasonably tight(no excess play/wobble) in the bearings.
The quill LOCK end has a sleeve for a bearing, and the quill STOP end bearing is inside the quill return spring housing.

Early Mark V Greenie Headstock Casing
Yes, The above is excellant information. I find I may have to grind additional clearance in the casing to prevent the quill feed assembly teeth from rubbing the housing.JPG40504 wrote:Since yer Greenie has a low SN, I assume it may be a sandcast headstock.

That is indeed GOOD NEWS, and a surprise to boot! Wonder if the design was altered, or problems reconsidered or ??????nuhobby wrote:Oh... just off topic, but I thought I'd mention.
PowerPro upgrade can fit the sand-cast "A" headstock. All specific instructions are included in the manual. (Better news than the grapevine had last year.)
FWIW the 'misssing' access hole would not be a hindrance since 10 hr oiling is no longer a maintenance requirement!!!Hooraah!

Thanks guys, I'll take a careful look when I start putting this thing back together.
Rather than start a new thread I'll ask here: How do I determine if my greenie (SN: 309753) is a sand-cast "A" headstock?JPG40504 wrote:That is indeed GOOD NEWS, and a surprise to boot! Wonder if the design was altered, or problems reconsidered or ??????
