1934 Ford BB 1.5ton Full Floater Axle

[Nico73]

Hello Ford Enthusiasts,
my Name is Nico from Germany, and i Need your help.
Since February i am rebuilding my Dually, and try to remove the rear brakedrum from the Full Floater axle. I allready take out the driveshaft, but there is a Spring-Ring that secures the big washer ( to adjustiert the bering clearance).
Are there any drawings of that axle?
The Spring-Ring Movies a Little bit, but i cant get him out

Greetings out of the Workshop, Nico

I also have a 1934 BB, but never took the rear apart, so I will learn with you.

Take of the hub cap, remove the nuts that are on the studs around the axle flange. Hit the end of the axle with a big hammer which will cause the axle stud conical locks to come loose. Pull the axle shaft out, bend over the tabs that are holding the axle housing nuts, remove those nuts and the bearing behind them. It the brakes are backed off, the hubs should then come off.

The parts book does not show a snap ring.

To get thehub off you remove the disc with the holes(1124), then the nut underneath(4255), in the parts picture you wre trying to remove 4245 outer grease retainer--i thing you only need to remove that "snapring " if you aretreplacing the bearing--I don't remember the exact number of holes the inner nut is backed off after it is tightened to give the wheel bearing clearance when the outer nut is tightened

You are correct but that is behind the inner bearing not where he is showing.

There are two part numbers for the BB-4245. There is the BB-4245-A inner seal that was used as a replacement from 1930 thru 1934 and the BB-4245-B washer snap ring that was used from somewhere in 1934 thru 1947. This sort of indicates some kind of change there with the inner seal in 1934. Anyway, There should be enough info now in previous posts to get the job done.

In late 1934 they changed to the full floating rear axle so a lot of different parts
from the 1930-E34.

Good Morning Gentlemans,
thanks a lot for your Support, finaly the Job is done well.
It's the spring-Ring 4245 that holds the locking plate 1124 in Place.
To get it out, i moved 4245 a Little bit clockwise to make it loose.
Then i pulled it slowely out. Attached a detailed pictures of both Parts.
Thanks Bob to providing me with the explosion picture, that helps me a lot.

Please excuse my horrible englisch grammar, i Hope you understand everything :-))

OK, I'm sure this problem is long solved, but a few points to those seeking info AND the right way to perform this task. To removing the outer cone bearing in order to remove the brake drum and wheel hub (axle has already been removed):
1. Remove the lock nut (BB-4252-B).
2. Thread two 1/4-20 bolts into the threaded holes in the locking plate (BB-1124-B). This pushes the locking plate off the pin on the locking nut (BB-4254).
3. Pull the locking plate and spring clip out of the wheel hub. NOTE: the spring clip holding the locking plate DOES NOT sit in a channel or groove. DO NOT try to pry it out - it just slides out of the hub with the locking plate.
4. Remove the locking nut (BB-4254).
5. Remove hub and outer cone bearing.

The illustration posted by Bob C shows a 1935 or newer full-floating axle. The 1934 full-floating axle has an entirely different grease seal assembly. It is described in another post in this thread.

The attached thumbnail shows the grease seal parts unique to 1934. The axle housing is also unique to 1934 as it has a a groove or channel that the compression ring BB-1175-B rides in.
