You can send your parts or the whole thing to Jacob Anderson or Bill Mayo. Both can do the work.

Below is information on how to reach them:
Bill on the forum or at his
web site Billstoolz.com,

Jacob Anderson is on ebay:
e-mail: jacobvb@yahoo.com

Almost all the bearings can be replace, with the exception of the bearings on the idler shaft (the middle shaft). It those go you will need to purchase the idler shaft from SS.

I'm not the expert on this, just well read and currently working on my headstock.

Bill has been very helpful and so has Jacob.

I hope this is useful and of some help.

Best of Luck,

Dan

P.S. Jacob makes two DVDs on how to repair your headstock and motor. Excellent reference material.

Tried removing the nylon piece with the screwdrivers but it was not budging. Instead, took an adjustable wrench and used it to "thunk" the thing off. Took about 10 wraps but it worked pretty well.

There was no "spring type retainer" like you mentioned. At least I didn't see anything other than the nylon piece.

Can't figure out why the nylon part description (part #57) is "drive and ring assy". All I see is a single piece of nylon. Not much of an assembly.

Thanks bucksaw for the part numbers of the bearings. Since I have the beast apart, I am going to change them all. I located a bearing source company here in S.D. today. I'll be bringing my stuff down this week.

You have 'encountered' the differences between a gilmer belt and poly v belt drive shaft(sleeve) assembly. This difference is one reason the 2 bearing quill is not compatible with the gilmer version. No it does NOT have a retaining spring.

Why is the idler shaft bearing an exception which warrents a replacement shaft?

I believe the idler shaft bearing is actually a water pump bearing assembly. Those bearings are manufactured as an integrated unit with the shaft. You can probably find a replacement if you search hard enough, though it might be easier to order the parts from Shopsmith.

When I rebuilt my headstock a few years ago, I purchased new drive sleeve and motor bearings from McMaster-Carr. McMaster-Carr doesn't list manufacturers in their catalog, but I ordered their "Precision-plus" bearings and they shipped SKF's at the time. I opted for double sealed bearings. The originals on my machine were double shielded.

SKF 6203 2RSJEM Motor, double sealed
SKF 6205 2RSJEM Drive sleeve, double sealed

I used a bearing separator and arbor press to remove and install the bearings. Be careful to apply force only on the inner bearing ring when installing them.

i'm sorry. i did not follow the thread close enough. i was talking about popping the nylon drive on the poly v system. the plastic sleeve on the gilmer does not drive the quill shaft like the one on the poly v does. the poly v main shaft does not have a metal spline, the gilmer does. not sure of the purpose of the piece that you show but am familiar with it.

On the Gilmar drive the nylon piece acts as a dust shield. It is missing on my Greenie and the lack of one has not caused any problems. I don't believe you can purchase a replacement.

Two bearing quill is not compatible with gilmer drive sysem??? That means if I was to go with the quill upgrade that I will also have to upgrade the drive system?
