A good buddy dropped by yesterday with his box of tools and helped me rebush my spindles and install new kingpins (and by "helped me," I mean he did the job while I watched and kept track of the 11/16th" wrench), thus saving me a few hundred bucks worth of tools and the aggravation of figuring out how to deal with things like aftermarket bushings that aren't properly chamferred and kingpins that don't fit.

While putting the front wheels back on, we noticed (and by "we," I mean he spotted the problem and I said, "Oh, s@#%*!") one of the inner ball-bearing cones was badly galled. The problem, now, is that none of the Big Three parts suppliers list the inner ball-bearing cone in their catalogs. Does anybody know where I can find this part?

(Up to now, the original ball-bearing setup has worked just fine and I'd rather not go to the expense and hassle of switching over to roller-bearings.)

Bumpity bump bump!

No one is reproducing these? Are they available directly from Timken?

David and Dan,

I've found a friend on the forum who can supply me with one. From what I can gather (and I'm often wrong), a few of these inner cones are still available, but they're not presently being manufactured.

I suppose if push came to shove, I could have brought the old, galled part to a machine shop and had them turn one out on a lathe, but then there might be the issue of heat-treating and hardness.

Bob, the Timken bearings can often be found at swap meets or on ebay at very reasonable prices. Just keep your eyes open and do your homework on what they are worth. Don't be afraid of using used ones, just make sure they are in good shape. Dave

Call Lang's. I'm sure they have some.

Bob was inquiring about ball bearing cones, not Timken roller bearings or races.

Apples vs oranges.

There seems to be some controversy over whether ball-bearings should be replaced with roller-bearings. The late brass car guru, Harold Sharon, seemed to think so, based on the ball-bearing type's propensity toward galling the facing parts. But I've also encountered other experts who disagree because of their continuing success with original equipment. I also notice, just by having lurked around the forum, that replacing the balls with rollers isn't as straightforward an operation as the advertising might lead one to believe. I've heard that some guys have had a hell of a time getting the new parts to fit.

In my case, it seems Harold Sharon was right. One of my inner cones did indeed get badly galled and so, here I am on this thread, talking about where to get a replacement part. Turns out, it's not all that difficult to find. I'd rather replace a ball-bearing cone every ten years (because it's easy and I know how to do it) than go through the hassle of switching over to rollers. I may be forced down that road if parts availability dries up, but until then, the path of least resistance still looks pretty good. And besides; it's kinda nice to keep the car as original as practical.

Bob, there should be no problem getting modern cups fit to an early spindle. Any trouble encountered will be:

mangled end of the hub where the hubcap goes on...sometimes swelled or oversize if the old race spun (will happen with later hubs too).

In some rare instances the radius at the base of the outer race's OD is a bit generous and the radius of the back/OD of the race will interfere. If you check first with radius gages, you'll know ahead of time and won't get into trouble. BTW, I've seen this on later hubs, too, where the new Timken race have a smaller radius on the back side than the original, and the same issue crops up.

So, the bottom line is, that there are no new or insurmountable troubles with fitting tapered roller bearings to early ball bearing hubs.

You will find that the outer race comes to the very end of the hub, or even slightly sticks out, as opposed to being slightly recessed when installed into a later/longer hub. That's no problem, and that's why vendors sell the thinner tabbed washer to use between the outer bearing and the castle nut.

Note: in first sentence, replace "cups" with "races"...don't know what I was thinking...
