What might be wrong with this photo of a 1912 Rear Axle that doesn't seem quite right at the Transmission end?

1912

No flange or cut back too far on the upper bushing or the pinion is too far into the rear end.

I would open it back up and check pinion gear position, pinion bearing (or if modern), front bushing flange dimension, (if not faced enough), drive shaft, and universal.

No experience with this early two-piece design, but to me the giveaway if this was a later torque tube is the nuts holding the radius rods are no where near the cotter pinhole in the threaded end of the radius rod. On later axles, you fit the front castle nuts first and cotter, then tighten up the lock nut behind the flange on the torque tube.

James, you don't say whether you have had this assembly together before. On more than one occasion, the front casting for a two piece torque tube has been added to a later tube to make the earlier part. Perhaps this is what you have and the casting was not installed in the correct position.

It is relatively easy to pick if this has been done. The later tubes have a longer machined section at the front and when the earlier casting is added, there is a section of machined tube about 3/4" long at the back of the casting. On a genuine early piece the casting is almost right up to the end of the machining.

Hope this helps.

Allan from down under.

Did you use the "cup" style driveshaft ball bearing in the driveshaft spool? I have heard of some people using the later "non-cup" style in an early spool (I would not recommend this). We have found differences in the thickness of the "non-cup" style. Also, if you put a gasket between the spool and driveshaft, it will move the whole assembly forward like your photo shows. The sleeve at the rear of the driveshaft could be too far forward. It should be right up against the pinion. If there is wear on the ends of the sleeve or the thrust plate of the thrust bearing, where the end of the sleeve rides it will move the driveshaft in an opposite direction of what your photo shows. Maybe, if it is a new shaft, they drilled the hole off?

Allen, the piece was assembled from a pile of parts.

I'm not sure they were all from the same year.

I'm also puzzled as to why the radius rods appear to be a little too short.
