I hope those axle shafts were old.

In answer to the comment above, two of these photographs show the axles that were removed. In addition to those there is one photograph, the one with the gears now attached, showing the new Lang's axles that are 1/16" longer then original. These are the axles that will soon be installed.

What is the benefit of longer axles?

The benefit of the longer axles is that we can install the Rocky Mountain brakes without needing axle hub shims. When we install the Rocky Mountain drums to the hubs, it pushes the parking brake hubs closer to the backing plates. This eliminates the need for the shims to move the hubs outward. We will know for sure whether we need the shims when we get to the point of installation of the hubs which will come later.

If Bud would have made his new drums like the original Rocky Mountain drums, there would be no need for longer axles! Rocky Mountain riveted the stock Ford drums to theirs, so the axles stay the same.

Has anyone ever seen this cool fabricated tool.
What does it do, how does it work?

Looks like it's for checking / setting the pinion and ring gear mesh and backlash. It would help hold the ring gear housing in alignment during the process.

THERE IS NO NEED TO HAVE THE RIGHT AXLE HOUSING IN PLACE WHEN CHECKING THE RING GEAR AND PINION CLEARANCE. JUST BOLT THE DRIVE SHAFT UP TO THE LEFT SIDE AND CHECK THE CLEARANCE. I HAVE A HOUSING SIMILAR TO THE ONE SHOWN. IT WAS USED BY DEALERS AS A DEMONSTRATION TOOL TO SHOW THE INTERNAL PARTS AND HOW THEY ROTATE.

I am always impressed when Chaffins Garage takes an interest in one of my posts.

Thank you, Chaffins. I am using the book which was published about 25 years ago when you were one of the authors. It has worked on the other Ruckstells I have worked on, and am planning to do it on this one. I think this one was recently rebuilt, because the Ruckstell parts look almost new and the gears were meshing very well when we took it apart. Only thing I have done so far is to install the new axle shafts. I had to mill down the washer between the axle shafts, but everything else except the bearing sleeves will be same as it was before.
Thanks again.
Norm

You don't need to mill down that spacer! Just use the original fiber spacer that was supplied with the car when new! There are all these guys in this club that believe they know more than Ford did!

The bronze spacer was there when I disassembled the axle. It was in good condition. Just needed to make it thinner to fit the new axles. These spacers are advertised in the parts catelogs as working fine if you mill to fit. It is mentioned in the book as being ok to use or bronze or the fiber one is also good. I don't see a problem. I fit it so that the axles rotate when the housing is tight.

Both Larry and Norm are correct with the exception that it was Perfecto Co., followed by Glover Ruckstell, who would have designed and produced this under drive, not Henry Ford.

Mechanic Norm is dialing in the tolerance on the large bronze washer that replaced the babbitt washer, passenger side of carrier. Remember that he is dovetailing new and original parts. This washer takes up play due to wear. Chaffins produces these oversized so that they may be milled to exact standards.

Original Larry is referring to that original Ford fiber thrust washer in-between the axles that keep the axles biting into the spider gears during turns. Norm put this fiber washer back in the rear end just as Henry Ford did in 1915.

These are two wonderful Model T-ers. I am fortunate that they are so generous to my son and me with their skill, knowledge, and time.

That is not the washer I honed down. It was the one between the two ends of the axle inside the differential carrier.

The first two pictures above are for a TT truck Ruckstell. The lower two are for the car. I have the book on Ruckstell Axle and have the pictures there. Also have had many other axles apart, so I know where the parts belong. In the cut away picture you will see right in the very center between the ends of the axle. That is the washer I was refering to above.
