Can anybody help with modern part numbers?
Thanks, Michael

I have Victor # 49136 or National # 6507 (or6356) these are probably older numbers but the part store should be able to do something with them,

Hmmm, my list is showing National 6407 and NAPA 16246. Take the old one to NAPA with ya.

I dont know Josh , got those out of my old swaps book . You are right ,the old seal should have numbers on it,

Thanks guys for the P/N's. I will check them out. I do not have the old seals to go by, but I can measure the spindle surface area (assuming it is not worn too badly), as well as the hub ID and match these dimensions against the seal numbers you have given me. This Hudson has been apart a long, long time and there are no old seals to be found...

Roger, I have the lising for National as 6507 and I verified the #. I dug up a nos set on my shelf to confirm . I checked the measurements of my seals with the 16246 as given on the NAPA site the inner and outer diameters are exact, but the thickness of my seals is .283 and the Napa seal states .313. I don't see that as an issue . Ron

Thanks everyone for the response. Using one of the seals mentioned though may be a problem because of the shaft size. My shafts are 1.560 & 1.559 and the shafts on the seals above (that I was able to look up on the web) have a shaft size of 1.5625 & 1.563. I’m thinking that I need a closer fit than this (since the gap is about .003). To make matters worse, I was going to use a fine crocus cloth on the surface area, because of the discoloring. The surface area is not at all shiny and may have other microscopic crud… Any opinions…?

Thank you , I added these notes to my book,

mdwhit -
seals with a shaft size of 1.563" will work fine . I measured a SKF # 15649 and the ID was aprox. 1.505". That would give about .058" interference fit. I have used this seal many times. Norm

The seal Id has a range of @ 1.540-1.580, due to the inner spring loading the lip. You will be fine. If the car has sat for a long time with the spindle exposed, then there will be some oxidation on the sealing surface. Better to use the red or green scotchbrite pad cut into strips to polish this. Check that there are no dings or burrs. Dings and burrs can be carefully worked down with a small fine file, or a machinists de-burring stone and then polished with the scotchbrite.

Herm/Ken -

I had looked up the SKF #15649 and the specs. I read stated the shaft size as just 1.563. The specs. also stated that the seal was without a garter spring. Since you have used them Herm, I am sure I will find that there is a spring when I open the box. It also makes sense that it would be an interference fit, and have a range (due to possible wear on the shaft). Apparently there is something that I did not understand when I read the specs... So I am going to go buy two of those darn things tomorrow! Also, Ken - that's a great idea to use scotchbrite.

Thanks for the input guys!

I used a 9inch ford rear wheel bearing seal and it worked

Rockauto.com lists the seals for your car. Cheap and 2day shipping.

Larry - I had looked on Rock Auto, but there was no seal listing for the '48 & '49's. I went back though after reading your comment above, and did see one listed for the '50 - '54's (National part # 471831). So it should also fit the '48 & '49's. I really like the price, but I 'm not sure I want to order them, because the bore is listed as 2.445, and my hubs are 2.49 - 2.50. So it might be a little loose in my hubs. Also, the shaft size seems a little big (1.75), but it may have a range (like the SKF above).

BTW, I haven't bought the SKF's yet, as no one has them in stock in San Diego. Napa can order them. The cost for 2 with tax, comes to $40.00. So needless to say, I really like the Rock Auto price ($7.14 per seal (plus tax and shipping though), but it would be a hassle (and probably not worth it) to send them back if they did not fit. I will probably end up buying the SKF's...just experiencing a little "sticker shock" - never ever paid that much for a seal!

Thanks for letting me know about the Rock Auto ones though.

r2hud308 - just curious, do you know the part number for the 9 inch Ford rear wheel bearing seal?

r2hud308

Dont have a part # but I think most 60s and 70s 9" will work. What I liked about it is the seal was the same inside and outside diameters ,but it was a bit thicker which meant the lip would be riding on a brand new surface
