Tom,
According to the Hudson Manuals, those are the correct parts. Do you have installation instructions? The tapered bore bearings hence the "T" suffix) require a certain procedure. Many will jump in here and tell you how it's done. All I will say is [i]do not[/i] use a press.

Frank,
I have the procedures manual but the instructions call for a tool to remove the rear wheel bearing cups and axle shaft then removing the cone from the shaft. The tool appears to be a slide hammer. Does anyone have a more complete set of instruction? Does anyone have the J-352 axle shaft & bearing puller mentioned that could post a picture of it.
Thanks again
Tom

Tom,
The puller shown is just a slide-hammer puller with an adapter to the 3/4-20 axle-nut thread (assuming it's the same as the later thread form). The axle should come out without a great deal of effort, bringing the cup out with it. . I suspect you could put the drum back on very loosely, without the drive key, and use it as a poor-man's slide hammer. The auto-makers liked to specify that you use various special tools, implying that they are required to do the job. I suppose it brought business to their dealership repair departments and covered their tails in terms of liability.

Thanks Frank

Hello All,
I have an update on the 2581-T cone bearings. I found a distributor that sold my Tyson brand 2581-T cones. I purchased two . I've also found another warehouse that says they have several hundred NOS 2581-T Timken's. I purchased two with the matching 2523 cups. I've attached a picture. Apparently the 2523 cups are still in production as they are used in many applications. I measured the Timken and Tyson bearings more closely and they are within a few thou of each other. The outer cage on the Tysons are thinner and don't appear quite as round or nicely formed as the Timken. I attached a picture of them next to each other. Anyway, the warehouse would only sell them through one of their distributors, one of which is a company I already do business with through my work. The price through the local distributor for the Timken are also a little less then the Tyson's.
If anyone is interested in these it's looking like $28.00 each for the Timken 2581-T cones plus the shipping. The cups should be available at NAPA or the like but I didn't verify this. If folks preferred I could get the cone & cup in sets for $38.00 plus shipping. I figured that having to go through a distributor and that I've already got that covered may make this the easiest way to get this done. I posted this on the old forum. Jon B the administrator on the old forum had suggested I submit an add to the WTN for those who may not be online.
I'm not sure if this is the place for this post but this is were I started it.
Tom

Tom,
Good work! :cheer:
I'm "in" for 4 of the Timken 2581-T cones. Cups are common so there's not much point in shipping those. What's my next move to seal the deal?
Frank

Tom,
Chk your PMs, plz.

Tom, Count me in for 2 pair of the 2581 T cones please.

OK Fred . I have four people so far including yourself. I'm going to wait a another week or so before I place an order to see if any others are interested. I'll keep you posted.
Tom

Tom,

Already posted on the other forum that I would take the two sets for my 35. Let me know how you would like to proceed.

Thanks for chasing this down.

Mike,
I'm going wait a little while longer to see others are interested. I'll keep you posted.
Tom

No worries, They are going to be spares so I have them when I need them.

I will ask if anyone from the Gem State Chapter would like some.

Mike

Hello Everyone,
I have another update about the Timken 2581-T cone bearing. I looked they up in the Master Chassis Group Parts Book. It appears this bearing is used on the 33-34-35 Terraplane, 34-35 UCo & 89-90. I edited the topic to add 33-34 for those years. I would be good if someone could verify the parts book as being correct. Anyway, I'll wait a little longer before placing an order for those who've already chimed in.
Tom

I would be interested in 4 of the bearing cones. I can get the cups locally. Let me know the total with shipping cost.

Tom
