Trying to get my Model A to round up this year. However, the brakes need to be addressed. I ordered the speedway motors Buick drums and hubs. As always things are not what I thought. I actually have 48 - 52 Ford square back spindles on my car. It seems that the outer bearings are the same part numbers 09074. The old inter wheel bearing currently on the car (part #14130) is a bit larger than the included 15118 bearing from speedway. Has anyone gone through this already and have the correct bearing part number to fit these 2 together?
You evidently have F-1 spindles on your car. There is no bearing that will let you put early Ford (or Speedway's repop hubs) on those spindles. Couple choices. Get a pair of '48 and earlier spindles. Or Get a pair of F-1 hubs, can't remember if you need to machine the drum register or make a centering ring to fit the drums. These will space the drum out about 1/8"; but shouldn't bother. Or Machine the inner bearing and seal areas on your spindles to early Ford specs. Different spindles probably best choice.
Here is your 15118 bearing with dimensions. https://bearingsdirect.com/15118-15250-tapered-roller-bearing-1-3-16x2-1-2x13-16-15118-250/ I'd call them with the bearing dimensions you need, see if they can provide a part number with your dimensions.
This MAY be the stock inner bearing for your spindle and hub. See if the dimensions work with the stock setup. https://www.123bearing.com/bearing-housing/roller-bearing/tapered/14130-276-timken
@RICH B , just trying to clarify. Are you saying: There is no Ford part number that will let you put early Ford (or Speedway's repop hubs) on those spindles? Or, there is no bearing in the Timken catalog to make this swap possible? Or, there are other reasons this won't work, beside the bearing problem? Thanks, I just want to understand, as I learn.
Get a bearing dimensions catalog. They used to be paper and I have one some where, but probably can’t find it. I’m sure you can find one on line. Measure the dimensions of what you need and select the bearing! What a lot of people are unaware of is, most bearing cones have many races that will fit it, like wise any race will have a number of bearing cones that will fit it! Not on cars, but I used to increase the size of spindles on big tractors , that broke the spindle hauling huge hay bales. Many times I increased the diameter of the spindle by a 1/4 inch or so, while retaining the race in the hub! PS. There are also bearings that have a larger load capacity, but have the same physical dimensions! Bones
Good questions. There is Timken catalog on line that you can download as a PDF. If you look up the F-1/F-100 inner bearing all the cups that go with it are larger than the bore in early Ford hubs. If you look up the cups that fit the bore of the early Ford hubs all the matching bearings have a smaller ID than the diameter of the inner bearing on an F-1 or F-100 spindle. If you look at an early Ford hub there isn't enough room to bore it out for an F-1 cup without getting (I think) too thin; maybe Speedway hubs are clunkier and have enough wall thickness; but unless you are or have a machinist on call; different spindles are still easiest.
Looking up the 52 F 1 wheel bearing for the Hubs I harvested off one I also checked the O'Reilly computability chart and That inner bearing fits Model A through 32 and then 46/48 and 48/52 F-1. They don't show a race though. The Ford trinket vendors don't give real part numbers and info is somewhat conflicting. The cup/race for a 51 F-1 inner wheel bearing is a National 15250X that is 2.5 od. I'm not finding anything on a number for a race for a 40 hub but no doubt someone has that in their file.
That listing is wrong; F-1 uses a larger inner bearing and cup than early Ford due to the changes in the spindle. Check the list for '53-'56 F-100 for the correct numbers.
A follow up. F-1 uses a 14276 cup which is 2.717" OD & a 14130 cone which has a bore of 1.3125" (1-5/16"). Early Ford uses a 15250X cup which is 2.50" OD & a 15118 cone which has a bore of 1.895" (1-3/16"). Cone in the picture has the Ford B-1201 p/n. If you match a F-1 cup to an early Ford hub it is quite evident that there is not enough metal there to bore it out for the larger cup. A while back I looked thru the bearing catalogs to see if I could find some way to make Early Ford hubs fit an F-1 spindle and could find a way to do so. In that case we used F-1 hubs with '40 drums and Lockheed brakes. Don't remember the specifics and I don't have a old Ford drum in my garage right now to figure it out again. F-1 stuff on the left and early Ford on the right. F-1 stuff perched on a '40 hub to show how large is in comparison to the hub. Maybe a scant 3/32-1/8" wall left if bored out to fit.
