I want to get a rear hub chromed. I have a pretty nice one, so I want to remove the bearings and races and send it out. I've got a manual. I can't for the life of me figure out how to move what they call the "distance piece" which is the spacer between the two bearings. I believe I need to move this spacer over to one side so I can tap out the bearings from the opposite end, then remove the grease seal and spacer in the middle so I've got all moving parts out of there. Since the hub size is substantially bigger than the spacer, I would image it would move to either side pretty easily. Since mine doesn't, does that mean the inside of that hub is just backed with grease and whatnot, not allowing the spacer to move aside? I see in the manual that they suggest moving it with a drift and hammer. Thanks Triumph, sounds good. I gently did this and it didn't seem to work and only started dinging up the inside of the spacer so I quit. I can't see a "grease retainer shim" in there to collapse. Does pounding on the spacer inside the hub collapse the unseen "grease retainer shim" so the spacer can move aside and the bearings can be removed? That's what it sounds like in the manual but figured I'd ask before I go beating the shit out of it and make it worse.

Any suggestions?

Bill, I just took apart a couple crusty hubs to get chromed and I couldn't move the distance piece either. Hammer and drift didn't work. Couldn't catch enough of the bearing's edge. So I said fuck it and got a blind hole bearing puller set from Harbor Freight ($60). Bearings came out with only a couple hard slides of slide hammer. Didn't fuck up any of the shims and spacers either. I figure I'll use the puller set on other stuff and every rear hub from now on since I plan on chroming every rear hub I'll ever have. I can't stand black hubs.

Exactly my issue.

I have them soaking in PB Blaster right now, I'll look into the blind bearing slide hammer if no one else pipes up with a cheaper idea.

Thanks MLL.

Awesome illustration right?

I made my tool out of some solid rid with a 90 bent in it, the chopped off till it fit into the bearing/sleeve.

after you get it all apart, throw all that dumb shit away, all I use is the center spacer, new sealed bearings, and the retainer rings.

P.S., thats an alternator bearing for some car, but the measurements are spot on, I run them in all my cotton spool hubs.

Great, that illustration sums up in about three seconds what I must have read over and over in the manual. I was attempting the right thing, it just seemed kind of stupid. The 90 tool makes sense, and leaving everything else except the bearings and sleeve out makes sense.

I just drove an hour to pick up that HF slide hammer deal so I'll give that a shot in the AM and if it doesn't do it I will be making up a tool just like that. I think I already have an old scrap 90 bend that just needs to be trimmed to fit.

Thanks!

no problem. be careful with that slide hammer, I keep getting a mental pic of the hub on the floor, both feet on the spoke flange, hunched over, puller locked in, sliding the weight violently upward toward your face, neck, and teeth just as the bearing gives up.

now I'll pm you my addy so you can send me all that free shit in return for helping you remove a couple bearings, and potentially saving your teeth. hahaha

KT, I couldn't get the spacer to move enough to get much purchase on the bearing no matter what hammer I used. We'll see tomorrow which method works on this particular hub.

And 66T, I've used a slide hammer enough to know not to do it in the direction of my teeth, but that description congers up a pretty vivid picture!

ah I see what your saying now I thought you just couldnt get the bearings to pop out ...and was using a drift at a angle to try and pop them out one side at a time ...Yea I have never had a problem with the spacer being stuck ....

Well, that took about two minutes. The slide hammer worked to get one side out and then used a drift on the other and it's off to chrome and ordering Timkens. Thanks for the help!

a neat trick i think i invented cuz i dont see anyone else do it. get a sturdy washer that is just slightly larger in diameter than the spacer inner diameter and the i.d. of the bearing. grind away enough material on opposite sides of the washer to fit through the inner race if aligned vertically with the shortened edges just clearing the inner race. drop it in the hub with the axle a couple inches down inside to catch the washer which will try to lay flat on top of the axle but since it is slightly larger than i.d. will lean against the inside of spacer tube but should be nearly flat. Drive the axle up and the leading edge of washer will lodge right between the spacer and bearing. use a rubber mallet and the axle will force the washer flat against the back of the bearing simply drive the bearing out with necessary force cuz the washer can take it. total cost = nuthing. plus you can reuse the grease retainer since you dident have to "collapse" it to move the spacer..

OK, so if you dont have a speedo drive does this dust cap just pop off?

i've never seen one taken off but there has to be thread cuz its the same hub as a speedo one i think. i'm looking at one too cuz its chrome and its such a clean look when running no speedo. i wanna put it on my new chrome hub. If i find out how to remove one before you do i'll let ya know.

Yes,
it should just pop right off with a little GENTLE persuasion.

yours should be easy, the notched ring is in place of what hes got. i use a screwdriver shaft placed in the notches. sometimes a little tapping with a mallet and it will spin off.
