We had a little "catch" in the rear end:
That's to be expected with a Model K, as the engine simply delivers too much power for a car that size.
Rob that's too bad, that's my fear of owning a very rare car if things like this happen where do you find the parts?
I guess if you have a close buddy that owns a machine shop that can make the parts... That would be great.
I have access to a friends shop but I don't think either one of us has the know how to make gears. He has the machinery to do it but no experience...
I've made two sets of 1909 door latches in his shop, but I haven't built anything from scratch sense.
Good luck on getting the K going.
Rob, I see two sets of Hyatts. The longer ones go outboard?
I like the ball bearing thrust plates. Are the balls peined into their pockets or are they loose and assembled with grease?
Rob,
First choice have some replica gears produced [see: www.labthreads.com -- there is an article about them in "Hemmings Classic Car at: http://www.hemmings.com/hcc/stories/2010/04/01/hmn_feature19.html ]
Second choice -- there might be a possibility of using either Model T; 1928-31 Model A; or 1932-48 Ford V8 rear alxe parts. The tread is the same 56 inches on all of them. And I know that the T rear axle will fit and function in an NRS&SR rear axle housing (some modifications are required but I'm 90% sure you cannot see them from the outside of the rear axle housing).
Third choice -- locate some original gears -- but I suspect choice one or two above would be quicker.
Good luck and thank you for keeping us posted on your progress. I suspect very few of us have ever seen photos of the K rear axle taken apart or the engine etc.

Rob, for a better sense of scale, do you have a Model T carrier that you can place next to your Model K carrier shown in the second photo? Model T carriers are 6-1/2" o.d.
Also, are those spider bores poured with something? It looks like there are two different metals there and one at 4 o'clock blew out.
A gentleman here in Michigan business is making rear Axle gears. He has made them for Kissel Cars and brass era Oldsmobiles . Contact me and I'll give you his contact number.
Are those ball bearing thrusts original components or something adapted at a later date? They look like turntable components. When you see ball bearing thrusts in that application they are typically single row with matching grooved raceway washers in which the balls roll, both for alignment and better load distribution on the ball.
Rempco in Michigan has an internal group reproducing antique car gears to order, http://rempco.com
That is the place I was talking about, I couldn't remember the business name but am a friend of Red Hall he works there and is a Model T guy first class guy and does first class work.
Tom , The longer hayets are the outer. The balls are crimped in place they do not fall out
I highly recommend lab threads and gear works. Talk to jerry chase, he is brilliant and can make anything you need.
This photo has A T brass & steal thrust washer for size comparison.

I thought you told Dean to slow down the last time he went out for a spin.
Well Rob, I'm glad you found that as a result of dismantling and inspection. It would have been a whole lot worse if you'd found it as a result of a catastrophic failure...
UMM !
OLD SAYING BUY BOB TREVAN ---

Yeah, that is going to be fun. However, it shouldn't be too bad. I have heard good things about some of these gear makers. Whats a few extra grand anyway?? (Says the fellow that is too broke to buy much of anything right now)
The other possibility is to adapt and fit a '10s era midsize car non-Ford axles, gears, and differential inside the K Ford housings. Often, it can be done with mostly simple bearing modifications and fitting. Gear ratio must be considered, along with compatible axles and size.
Of course, I would only recommend that as a desperation move if a lot more than the gears are bad. As long as the differential carrier and axles are repairable? New gears are the way to go. (I do notice the the carrier is broken, but I consider that to appear repairable)
Have fun!! I know you will.
Drive carefully, and enjoy, W2
Is this the items you are looking for Rob ?
The good news is that the parts can be made by a competent machinist. Made from modern materials they should never be a problem again.
There's a chance someone who made a set in the past would be able to do more. Just need to know who to call.
All this talk of adaptation -- if you're having to pay for the labor, it is typically more economical to reproduce correct parts than it is to pay the labor to cobble something together (if paying for labor is a factor). There is also value added to having a significant car, such as this, that has not been cobbled.
I will also put in a plug for REMPCO. Red Hall does excellent work and they are all business. He is also a MTFCI past president.
I think I've seen a reference to the model NRS rear axle that the rear axle Hyatts were rolling directly against the rear axle housing, no replaceable outer race. Did the Model K have outer Hyatt races?
That's three recommendations for Rempco, plus he's a Model T guy! Sounds like the way to go.
Thanks for the suggestions. I called Red at Rempco yesterday following a few recommendations from friends who have had gears made there. Looks like we will probably go that route.
While Dean is doing the "peripheral" work like dismantling the diff, I'm focusing on the important part of getting our car back on the road.....
I'm sorry for your temporary loss Rob but glad you had so much fun at the O.C.F. with the K this year. Keep us posted on the progress.
Looks like you have Holly working really hard on getting the shine back in those lamps. Remember to tell her that she is doing a great job.
Now THAT'S funny!!
I have on occasion referred to the Model K rear axle as a Model T rear axle on steroids. Looking at these photos, I am thinking that might have been a bit of an understatement.
Mr. Karlsson, to answer your question, yes the Model K used roller bearing sleeves.
Rob, don't forget that the Model K rear axle parts drawings are in The Benson Ford Research Center on film. There is no good substitute for making replacement parts from the original drawings.

Hi Rob.
Just had a quick look in my ''K'' spare items as pictured .
I note from records that there should be more bearings and sun wheels with items-- I will look further if interested?.
IS YOUR CAR AN EARLY PRODUCTON CAR WITH NON TAPERED AXELS ENDS ?
Bob,
Thanks for the post. If you have the spiders and all is serviceable, I would be immensely interested. Our car is the later 1907-08 with tapered axles (yes, another Model K feature that Ford went away from initially on the Model T).
I sent a pm, thanks again,
Rob
