reaming the ID of a bearing? Tech help?

Hi guys, This may be a dumb question, but here goes:

I made a new steering column today, got a bearing for each end of my stainless pipe that fit perfectly, and the bearing slides on about 1/4 of the way on the shaft. I am SOO close to it sliding all the way down. I just need to take a C-hair off the inner diameter of the bearing, but it keeps spinning when I get aggressive with the sandpaper.

Is there any secret to doing this that I am missing, or am I just going to have to tape some sandpaper to my finger for another couple of hours and back-and-forth it?

 

Polish the shaft.

Much easier.

 

I tried that. Might work for a blonde C-Hair, were talking more like a red or brunette one.

 

Can you use a 3-stone brake cylinder hone and a variable speed electric hand drill?

If polishing the shaft doesn't work for you,and the hone does not fit,and you are that close you can always take a short piece of bar stock, rod , or wooden dowel with a smaller I'd than the bushing hack saw a split in one end . Then wrap 6 to 8 inches of 1 inch emery clothe locking it into the split in the bottom of the rod ,stick the other end into your drill and proceed to polish the I'd of the bushings

 

Actual measurements would be beneficial. Are you out 1/32? 1/16? what?

It's hard to tell the thickness of a curly when it's stuck in your throat.

 

also... warm the bearing up, and freeze the shaft...

 

Freeze the shaft and heat the bearing.

Sorry, didn t see the answer above

 

Take the bearing to a local machine shop and have the ID of the bearing honed, honing is actually controlled grinding with lubrication.

 

He, He!!

"It's hard to tell the thickness of a curly when it's stuck in your throat.".

Sound's like this should be over on the Bullet.

Did you try K-Y ?

 

Valve grinding compound on a wooden dowel

 

I'll try to take down the shaft a bit. The challenge I am having with honing the inside is the piece spins, remember it is a Bearing, not a bushing. Getting that center piece to hold still.

Double post

 

Bearing are stock replacement parts, Shafts are not.
I don t see the point not not adjust the shaft.
File, sand paper, anything will do.

 

The bearing is hardened steel, you will have better luck polishing the shaft. Plus if you ever have to replace the bearing, the new one will fit right on.

 

Funny this wasn't realized...

 

I have a pinion bearing for a 8 3/4 that I honed out to set up gears without having to press it on and off to change shims, when I am done I use the new bearing and its always been dead on.

How often does one have to change out a collum bearing anyway??

 

How did you Hone it?

I have tried to grind stuff like this before, its a *****. Heating and freezing is best.

 

Used a Sunnen rod hone

 

Not often we get a thread talking about curly red c hair and polishing your shaft. I have the problem ( even at my age) of expansion when polishing my shaft.

 

Now the bearing is full of sand and
small metal fragment. Get it real
clean. Or it wont last long
Not an easy task
I would by a new bearing and heat it
and it will slip on real easy

 

A cheap porting kit for 30 bucks with some sanding rolls in it
would work good then you have some around for other odd projects

 

I think the original question is referring to a $5.00 self contained flange bearing, likely 3/4" id, the type used on the front wheel of a riding lawn mower. Some postings seem to be in reference to a bearing with a separate race.

 

I've used a dremel tool with a small grinding wheel. working it around the entire inside diameter. It will loose a little in concentricity but should not be a big deal for your application. Yes, cleanliness is a concern and having the proper diameter shaft will simplify future replacement.

 

Use a flap wheel in a drill to hone the inside of the bearing. I have used this on an extra set of carrier bearings to set up a rear end and it worked great. You can find the correct flap wheel at a good hardware store.

 

Most likely inner race-bearing and outer race...much easier to do with a die grinder, etc...have mine from the last Dana 44 I set up...hope the kids don't toss'em when I die

 

Thanks for all the replies. I ended up sanding the shaft with my orbital sander. It took a little time, but I got both bearings to slide on like a machine fit, with a little grease.

The inner bearing was hardened steel and a real PITA to remove anything from it.

 

Now this is a correct job
