Replacing Trostel grease seals, anybody know a good cross-reference?

I'm repacking the bearings on our 1966 Streamline Countess 26', and I've got one hub off and on the workbench.

The good news is that the bearings look to be in good condition, they spin freely, and the grease still looked good.

I cleaned up the seal and found "Trostel 317-200-5" etched on it.

I tried to measure it (the calipers don't fit down into the hub) and the outer diameter is about 3.4", the inner about 2.1".

The bearings are LM6704 Bower USA.

Can anybody help me find replacement seals? I've been searching and poking around but haven't found those numbers referenced anywhere.

I also don't want to pull the seal until I find a replacement, just in case I need to put it back together temporarily.

I'm going to try a few auto parts places on Monday, but I'd appreciate it if anyone has a good book they could receommend.

Your going to have to go to a store to buy the bearings...take the bearing and the seal with you....they are not magic....any industrial supply will have what matches and will fit. I always go Timkin myself.

Your bearing number I believe, is LM 67048.

You left off the 8.

Andy, you were right!

I have tried calling a few local places, and took the hub into one shop. They took a look at it, found that it was made by Hadco, and declared that I need new axles.

I'm glad that I haven't destroyed the seal, but I do hope that I can replace the seals without resorting to new axles.

I measured the spindle and it's 2.0 inches, so i assume the bearing number indicates that it's a 3.17 OD, 2.0 ID, 0.5" thick seal.

The best resource I've found so far is this:
http://www.allsealsinc.com/trostelpd..._shaftsize.pdf

but alas I don't see a listing.

The hunt continues...

After further research, I'm not sure why the shop declared Hadco dead, I found them once I knew what to search for:

Hadco Engineering, Inc. - Commercial & Military Axles For Over 50 Years.

I'll post an update if I find replacement parts tomorrow. It looks like SixRobblees has them!

I have been looking for the same seal. It looks like CR SERVICES 20109 OIL SEAL might be a replacement.
