Model T Ford Forum: Forum 2014: Remove & Replace wheel bearing races
Top of pagePrevious messageNext messageBottom of page Link to this message  By Dick Fischer on Monday, October 06, 2014 - 03:55 pm:

I'm just about to replace the wheel bearing races (ball type) on a pair of wood spoke wheels. Does anyone have any special methods or precautions or advice in doing this task ?

I'm assuming that I will knock the old races out from behind with a brass drift.

To push the new races into the hubs, I'm still unsure. The wheel is too big to get into the hydraulic press. Right now I'm thinking about using a large diameter fine thread bold through the hub to pull each race into position. Any thoughts ?

Thanks in advance,

Dick

I use a punch and a heavy hammer to get out the old races and a block of wood to install the new ones. The old races can be a bear to get out sometimes. I use a steel punch. I think the brass punch may be to soft.

If you are not going to reuse them, weld a bead around the inside of the old race, cool it off and sometimes they will just fall out. KGB

Some early hubs won't accept the modern races,due to curvature built into the hub. This won't allow the race to go in far enough.Check before you start driving a race in.

Thanks so far, guys.

Jack D., when you said "modern races" are you referring to roller bearing conversions or is there a problem with even some replacement ball bearing races ? I have NOS ball races coming from Lang's.

I have been shown how to use the old race to install the new race. Place the new race in position, and place the old race on top of it so it will drive in squarely. Use a block of wood on the old race to push the new race into the hub.

Dick-
Make sure the ID of the hub is not bent or wallered over, or when you punch out the old races, you might split or damage the end of the hub.

Don't ask me how I know.

When putting the new races in I either use a press that I can run between the spokes, or use a hammer and a block of hardwood.

Maybe you could use a couple of blocks of hardwood (one on each side and a BIG C-clamp, and like Dave says, use the old race as a driver (maybe grind the outside edges of the worn out race just a tad.)

: ^ )

Dick,some of the roller bearings aren't machined in enough of a curve to fit properly.

Usually a pretty easy job if the cutouts in the wheel hub are big enough to allow you to get a punch in behind the race.

A little filing on the outside of the hub to remove any burrs and then just a matter of alternating the punch from one side of the race to the other as you drive it out.

Going in with the new race, us a block of wood as suggested. I lightly oil the hub where the race goes in and be careful to get it started square. When its flush with the hub it usually must be set further in, so I use the punch to drive it home with evenly spaced blows around the edge.

Now ... getting out a old race for a tapered bearing ... a tad more difficult.
