noise coming from the quill area.

I have an old 55 ot 56 green Shopsmith., I am the second owner and have had it since about 1973. When I bought it the Gilmer belt was broke and I needed to replace it and I did. The saw has worked well but now I am getting a squeel when the motor is running and a sort of a grinding sound when I turn the chuck by hand when the motor is not running. I am thinking it is the quill bearing and of course I can not replace it with a new 2 bearing quill for a reasonable amount. So I am thinking I need to replace the quill bearing. I can find the number for te replacement but I can not find how to replace it.

I did find on one of the sessions that Nick did how to take the quill out and that doesn't look hard at all. However, I have not been able to find the instructions or a YouTube video that shows me how I get the bearing out of the quill and the new bearing placed back on the shaft. I don't understand if I can just pound out the bearing and if so I don't know how I get the new bearing in the correct location.

So any help in how to get the single quill bearing out of the quill and get a new one in would be greatly appreciated.

I know it would be nice to just replace the whole headstock with the newer belt and the two bearing quill but this Shopsmith has become like part of my family and I don't want to replace any of my children. So again any help, suggestions and insights would be greatly appreciated.

Thanks in advance,

Hi and welcome to the Family;
If you have taken the quill out then you must remove the knurled collar by loosening the set screw and removing the collar. Behind the collar their should be an internal snap ring that has to be removed and then the inner shaft (the actual quill ) can be removed by tapping the splined end of the quill out. Tap from the left end in the direction of the tapered or right hand end of the shaft. Then it is a matter of replacing the bearing and re-assembling.

Replacing the bearing is an easy process. You probably won't need to have the bearing pulled or pressed back on at a machine shop. At least I didn't. Do a search on this site for the bearing you will need. The best source I found (quality and price) is from VXB Bearing in Anaheim, CA. Got quill bearing there 3 years ago and drive bearings last year. Do a search for their site.

While you are in the bearing replacement business you might want to replace the drive bearings as well. You will probably need to have these pulled and pressed on at a shop. Check with local tire shops as they are often much cheaper than machine shops.

The two bearing quill isn't a necessary upgrade unless you need it, which is typically folks who are going to go a lot of large/heavy faceplate turning. Otherwise I don't think the expense and trouble is worth it - just fix your headstock as is and it will serve you well for another 60 years.

As far as how to replace the bearings and otherwise service your headstock, you may want to check out some of the DVDs Shopsmith has produced on maintaining and repairing your Mark V:
http://www.shopsmith.com/ownersite/catalog/nevideo_index.htm

Jacob Anderson has also put together a couple DVDs on repairing the Mark V headstock and motor - I've never watched these but it seems like he knows his stuff:

I lubed everything last night and my machine does sound better but something is still making a noise.

I called Shopsmith today and got a lady in the tech. department who told me how to check to see if it was the quill bearing that needed to be replaced. She had me pull on the spindle to see if I could get it to pull out at all. I couln't get any movement. Then she told me to try to move the spindle from side to side and see if I could get any movement at all. I tried this and could get no movement at all. So it does not appear to be the quill bearing that is making the noise.

When I turn, by hand the attachment for the when I put the jointer on I get a noise like a belt squeeking. When I turn on the machine it may just be a normal sounding machine or sometimes I can get a higher pitch sound.

I tried to see it was only when I turned the speed control up and down and while it sometimes does it then I can set the speed control at a setting and it will sound find for a while and then without changing anything I can get the squeal again.

I am now at a loss as to what the noise may be and what I can do about it. If anyone has any suggestions I sure would appreciate them.

Thanks for your continued help
Chuck

We need to determine if it is belt squeak or bearing squeak.

Either is eliminated by the replacement of the squeaking thingy.

Since you can make it squeak manually, a stethoscope will help narrow it down.

Poly-v belt alignment?

A long screwdriver makes a decent stethoscope in a pinch.

I have the same thing, or very similar going on right now. I took the headstock off the rails and have it on my workbench. I have cleaned it out really good and need to oil it up (what is the best type of oil to use for this?). I thought at first it was the motor, but I took the belt off so just the motor would run and it sounds good.

Midnight, I read through what shopsmith told you to check, and I checked it on mine and nothing is moving either.

I was hoping to get a chance to make some ornaments and pens, but I don't want to run it until I know for sure I am not damaging it with the noise.

You just had to mention squeaking!!!

Since then My Goldie wants to screech! On/off for short duration.

Been putting off bearing replacement(main shaft/Motor) as it has the originals still in it.

Quill bearing got replaced already.

Put off is because a complete tear down/refurb is in it's future.

May have to swap out either or both for a temporary 'solution'!:(

Hope a different main shaft with new bearings will make it go away!

Murphy's law says it will be the motor bearing(s).

Question for those who have done the bearing replacement thing: is there a trick for making sure you put the new bearing back in the correct spot (or spots if a two bearing quill)?
