For those of us with the biggies:

On the full-floating axles (like the Timken 53566), are the bearings lubricated by the differential fluid (like modern floating axles), or do they need to be packed with grease? The shop consensus earlier was they should be wet lubed, but I came across this: Vintage Truck Magazine''s Message Board :: View topic - 36 Ford Full Floating Rear Axle Bearing Lubrication

Also, anyone have a good source for the seals?

 

Must be packed. there are seals to keep differential fluid out of the bearings. Try Green Sales at 800-543-4959.

 

Just curious - the bearing definitely looked wet lubed when it came out, and I don't see any seal in the diagram that would keep diff fluid from the bearing; just the one keeping the fluid from spilling out onto the brakes. Am I missing something?

 

Is this a question about a F-5? If so, it's not a Big Job. Now, my F-750 was wet, it was not greased. There are a few different axles that were. It really depends. Some applications had Rockwells, some had Timkens, and some had Eatons. There were also Dana, and I think there was another one in there too. Now, even if they aren't a grease packed assembly, you still need to put an assembly lube of some kind in the bearings prior to installation, as it does take some time to get them wet from the carrier fluid.

 

Howdy,

I have a Timken single speed axle on my F-600 and I have an Eaton 1350 2 Speed that's going to get rebuilt and go on. Both are "wet lubed" with oil from the differential. You do pack the bearings when you put them together because it takes quite a long time for the oil to make it to the bearings but it eventually gets there...

The axels were both wet lubed, but as mentioned they were prepacked for initial lubrication.

Here's some pics and specs for you:

 

I had to use another post to download the forth photo fullsize. Here ya go:

 

The seal is # 1175 (BB-1175-C).

 

That seal above, xx-1175-x would keep the oil from leaving the system and off the brakes. It doesn't prevent the oil from reaching either the outer or inner bearing.
