Idler Shaft

dusty · Post by **dusty** » Wed Nov 21, 2007 12:46 pm

Does anyone have the part number(s) for the bearing on the idler shaft. The top of my headstock is getting hotter than I like and I'm afraid a bearing failure is in my near future.

I can't afford the down time so I'm going to order parts before failure.

Are the two bearings in the quill assembly 6205ZZ??

Does anyone know the part number for the bearing shown in the attached photos. The bearing on the idler shaft. I believe this is a pin roller bearing - just guessing from its appearance.

Dusty, the idler shaft and the bearing are a single part; you cannot take them apart. The shaft is actually the inside race for the rollers. I'm told this part is also used in several different types of pumps, but it's not a standard industrial item that someone like Graingers or Motion Industries will stock. Grin and bear it, buddy, you have to get it from us -- #5041789.

With all good wishes,

The bearing on the main spindle or quill is item number 502962 with a price of $ 4.71 plus shipping and tax. This bearing also requires a bearing press for removal and replacement. The bearings on the drive sleeve are item number 501297 with a price of $ 6.51 each plus shipping and tax. All other bearings are not available separately.

This what I put into my mark V 500.

Thanks Ed. I have replaced quite a few bearings during repairs to the Shopsmith headstock. The idler shaft and bearing must be ordered from Shopsmith as Nick states. I got my initial bearing information from Skip Campbell as to what bearings to use as replacements. I get my bearings from http://www.ebatmus.com . I use the 202KDD5 C1 bearing ($13.26) for the quill and 2 of the 6205-2RS C/3 (11.86) for the drive sleeve shaft. These bearing works well for me as I have not had a failure using these bearings. If you replace the drive sleeve bearings, be sure to check the set screw in the drive sleeve pulley for tightness. I have found quite a few of the set screws being loose. I remove the set screw and use blue LocTite on the set screw and tighten the set screw real good, otherwise the drive sleeve must be removed to check the set screw. The drive sleeve pulley sets againest the back snap ring leaving a little space to the front snap ring. I put the drive sleeve assy. with bearings in the freezer for a short period and then install into the headstock with no problems at this time. I even heat the headstock opening for the drive sleeve with a heat gun. You must be very careful when installing the drive sleeve assy. to keep the bearings from cocking/hanging and no steel hammer/device allowed. You must not put pressure on the balls when installing any bearing. I use a short piece of pipe whose diameter is the same as the outter bearing race and use my hand for a hammer to install the drive sleeve assy. I use a spare quill shaft to help keep the bearings centered when removing/installing the drive sleeve assy.

I have only ordered the idler shaft and bearing from Shopsmith so cannot comment on the reliably or desirability of using any other bearings they sell.

Dusty, If you need the quill bearings real quick try Bearing Belt and Chain, if you can wait then order them from SS and save the gas from driving.

My 500 is singing at lower RPM's and i think it is the bearing on the idler shaft as it is getting hot. Did/does yours make any noise? Any other ideas as to what might be singing on mine?

I don't think bad bearings in the quill assembly will cause heat at the top of the head stock. I think the bearing in the drive sleeve will. There are two bearing besides the quill bearing at the top of the headstock. The drive sleeve has two bearings and every SS rebuilder I have talked to said they find these bearings to be bad. I don't know that is what I hear. However the top of my headstock has gotten hot since it was new and it is still kickin.

Thanks for the feedback, guys.

My machine and I are both getting up in years. The Shopsmith shows its age much better than I have. I already have all new running gears but they are not like new even now.

The Shopsmith is still running on almost all original equipment; I've had to replace the on/off switch. She runs hot though, as already discussed is this and one other thread. I don't know if this is a new symptom or not, I sort of think it is.

She doesn't complain though. No unusual noises, no slow startup, no fusey cuts - everything seems normal except the heat.

I just want bearings (parts) on hand so that when/if she quits, we can get back in service without a lot of delay. I'm making up am order to pass through management and I want it to be as complete as possible. That's why quill bearings (I may make that a quill assembly).

Thought about an OPR too but management is smarter than that.
