Shopsmith Bearings

hobbydad wroteJPG and Bill, thanks for the info. I should have the bearings next week, so I will have to look for a puller. As always, the users on this forum are a great help!

I used for many years and have recommended to other Forum members the following Harbor Freight puller http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=93980 when it is on sale for $29.95 or less than the normal $49.95 price. I have pulled and installed many bearings without any problems. Just remember to never put any pressure on the balls between the races as it can lead to early failure and noise. Be careful to not get the bearing tilted when installing. I have used deep well sockets and still use short pieces of pipe and machined sleeves to install bearings.

I'm needing a single quill bearing and two drive sleeve bearings for my "new" 1954 greenie. I've searched the forum and thought I had the numbers needed to order them, but when I search bearing sites for 6205ZZ and 6202ZZ I get several choices for the same bearing.

For example, at http://www.vxb.com/Merchant2/merchant.mvc? I get the choice between a $12.95 16mm one and a $1.49 15mm one. When searching for Fafnir 202KDD5 at Tamkin, I get many choices.

Does anyone have current order numbers from any company for greenie bearings that I could just call them and use the SKU number?

Feel free to PM me. Thanks.

I order my bearings by size, not by number. The quill bearing is 6202ZZ-5/8 (5/8" X 35mm X 11mm) (202KDD5 is the same size). The drive sleeve bearings are 6205ZZ (25mm X 52mm X 15mm) (205KLL2 is the same size) Each bearing number can come in many different sizes. I buy my Precision bearings from Bob Hill (bobhill5@earthlink.net). A nice gentleman to deal with. I like a shielded bearing over a sealed bearing but either are OK. If he does not have them, then I buy bearings on Ebay from jjdini3 first or irvineman. Price for the same bearing can vary quite a bit so shop around.

Thanks for your timely reply, Bill. I've emailed Bob Hill.

Will this gear puller on Ebay work? http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=350335068407&ssPageName=ADME:B:BCA:MOTORS:1123

Thanks,

For anyone interested, I emailed Bob Hill (see Bill Mayo's post) and got a price quote of $3.89/bearing for both the quill and drive sleeve ( for Greenie). Shipping is free.

That is similar to the one Bill recommends and I bought. The one I have is the Harbor Freight model and was on sale when I bought it for $39.00 and has worked flawlessly. The one you show on EBay only has one clamshell and the arms look to be too big for the type of pulling you will be doing on the Shopsmith. I would just order the one from Harbor Freight it was $60 when i went to get it but when i got to the store I was happily surprised ti find it on sale for $39.00. Best $39.00 tool I have bought IMHO!

Thanks, Michael.

That puller / separator will work. I use a similar onefrom HF. HF goes on sale for $30-40 occasionally if your not too anxious.

Brilliant! I spent the day tearing down the headstock on my new (to me) Mark V. Had to use a drift through to get the drive shaft out, only to find that at some time in the past, someone had managed to munge the bearings pretty good! It looks like they were 'eased' in to their holes with a hammer and screwdriver!

The unit would trip breakers whenever I started it up, but the motor ran fairly well without the belt on. Now I know why, and now I can find a local source due to this wonderful and brilliant list! thanks,

The Franklin motor that is in my 54 greenie has a 5/8" shaft and the bearings are 1 3/8" OD. The only markings on the bearings that I can see is "502-16 and ND". Does anyone have a number for these?

I mistakenly ordered 6203ZZ (I saw "Franklin motor" on the bearing numbers posted in this thread, but didn't notice that it was for a 3/4 inch shaft).

The '3/4' refers to the horse power of the motor, not the shaft size.

If they appear to be 1 3/8" od, they are 35mm od. Most motor bearings are 40 mm(1.575") with either 5/8" id or 17mm id. The 6203 should be the correct one unless the id is 5/8".

You need to measure the shaft at the bearing mount location.

My Franklin Electric 3/4 HP motor, which looks original to the 1954 Greenie, takes 6202-16MVV C3 bearings. The 5/8 diameter shaft is just slightly enlarged where the bearings fit.

Hello, I have not posted before. I hope this is found useful. I recently updated my 56 greenie with a used 1.25 HP emerson motor. The rear bearing was odd like JPG40504 said. I found that Emerson uses a .625 centrifigul switch on the rear of the shaft neccitating the use of a .625 bearing. I could not find the Nachi bearing 620310 NSL but did find this which seems to work very well from VXB bearings

rear emerson motor bearing 6203-2rs-10 sealed.

The front or "fan" motor bearing is a standard 6203

Hope this is a help.

It is also correct(1 1/8hp).:)

This thread was started in March of 2009 and the first post contained,

"The control/idler shaft bearing is >>>> Water pump shaft...shaft and bearing are one and is not repairable by the average joe. Anyone found an aftermarket replacement? Also, the small bearing on the speed control sheave is pretty much not repairable as near as I can tell."

Are there aftermarket replacements for these two bearings? If so, what are their specs so I can order them?

Why did the poster say they are not repairable? Does it take special techniques or tools?

I have a 500 of mixed vintage (not sure who the father is). In some post there was a comment about SS making a change to the eccentric. Did this impact the bearing?

It replaced the modified water pump bearing with two standard ball bearings and a new shaft design. The eccentric was changed at that time.

The control sheave bearing is also modified making it 'unique'. SS does not sell it separate from a sheave. I believe the water pump bearing is now obsolete. IMHO the new design is better!!!

JPG40504 wroteAdding to the difficulty of finding bearing part numbers is the variation in identifying part number with different manufacturers. This 'search' is greatly aided if one knows the 'size' of the bearing.

Therefore, the following: id x od x length

Quill (2 piece shaft).............................. 15mm x 32mm x 7mm doubleshielded?

.................................................. 17mm x 35mm x 10mm doubleshielded?

I believe this to be correct. If not let me know & I will fix any errors.

Minor correction: the 6002zz "length" is 9mm, not 7mm. And yes both quill bearings are double shielded.

What is meant here by the "water pump bearing"?

Thanks, Bob

Thanks, Bob

The idler shaft started life as a water pump shaft/bearing.

Due to current difficulty in sourcing them today(victim of transverse engines), the two bearing redesign is now produced. Tis backward compatible, but requires the newer eccentric design.

billmayo

I still prefer and use the old "water pump double bearing" idler shaft. I got an Ebay seller to offer a new replacement idler shaft and bearing which works well for me. I have not seen the old (original) bearing actually fail to where it will seize. It will make increasing noise when the wear becomes excessive. I already had to replace one of the new design 2 bearing idler shafts due to bearing failure. I question how long the either of the 2 new bearings will last operating at over 16.000 RPM. I have operated the older idler shaft up to 18,000 RPM for extended periods of time without any noticeable increase in noise even through it was not specified to operate at this speed range, normally 9,000 RPM max on the original Mark Vs.
