Finally got time to go check it some more. I first cleaned it with some acetone and then was able to get the tip of a Babbitt bearing scraper to make some scratches. Do to the silver color I am pretty sure it’s a babbit thrust washer. Looks like I need to plan to remove and rebuild the rear axle

Great ideas I will do it tomorrow and post a new photo
Tom

Tlitwin

From this photo can tell if it’s Babbitt or bronze?
Tom

Tlitwin

Are the new rear axles the vendors sell all made by the same company? Or is there a preferred one?

Thanks Tom

I took mine to American metal cleaning in Portland. Have not had any issues with it since they cleaned it. Cost 75$ in 2003.

I just wanted to share some information about the design I was able to work on. First I was just the tester as this electronic stuff is a little beyond me. It was my best friend, an electrical engineer, who designed this after I asked him what he thought about designing a regulator for the model t. ...

Luke We tested the 431 design for many hours on our test stand and it worked well. There was some oscillation of the amp gauge but as the battery came close to a full charge it became harder to detect. When we were testing we had both the mosfet and schottky mounted to a heat sink. Our plan moving f...

With the help of a friend we have built a prototype based on TL431 design I posted. More details to come. We have been bench testing and hope to test in a car soon. Looks promising

I know it does not look like the original ones but has anyone used this? They are very reasonable.

the TL431 off state current is typically 10na, max of 1ua

Tlitwin

What do you think about this design it seems simpler to me. Sorry for the blurry picture.
Tom

Tlitwin

Thanks everyone for all the information. I am definitely going to have the drums checked for cracks as I already have a few that have been scraped as the cracks are very visible.
Tom

Tlitwin

Looking for recommendations of a machine shop that can work on transmission drums in the Portland Oregon area.
Thanks Tom

I working on rebuilding a ruckstell. It was in fairly good shape only need a new P141 and a new set of spider gears. My question is about the bearing. My bearing is in good shape but the numbers on it match nothing I have seen in any threads and it has markings for thrust on the inner collar not the...

I found these links to 2 online articles. Very nice step by step instructions with photos. But it looks like the articles are from last year. https://www.hemmings.com/stories/2020/08/26/the-indisputable-necessity-of-replacing-the-thrust-washers-in-a-model-t-rear-axle https://www.hemmings.com/stories...

Do you use lock washers or self locking nuts? The bolts I have the threads look good so I’m thinking they were used with lock washers.

Tlitwin

Can you use small block Chevy rod bolts?
Tom

Tlitwin

Thanks all for the tips. Like Stan’s tip on keeping it the carrier so it stays cool.
Tom

What’s the best way to cut down a read end spider to fit a Ruckstell rearend? Grind it down or hack saw. Or?
Thanks

These pistons came out of motor that was rebuilt in the 60’s. No identifying makes other than “184” on the inside lip. Has strange relief around the wrist pins. Should I reuse them?

I think the 3rd main was getting a lot of metal shavings. Here’s the coil after the motor was pulled. I don’t think I had many miles left.

Tlitwin

Here’s some photos

Tlitwin

Thank you everyone for your comments. Here’s some more history on the motor. It came out of 26 touring. We pulled it two summers ago and replaced it with another one we had just rebuilt. This one has lots of miles on it and was last rebuilt in the early 70’s. I could tell it was getting tired and wh...

Tlitwin

How much can you safely remove from the mains? Mine currently mics at .020 undersize. It’s a EE crank. I think(hope) it should clean up at .025 under. Is that good or look for another crank. It’s out of a running engine so there is no rust or pitting on any journals. Just a little scoring on the thi...

You might check out Irontite all weather seal. The person who rebuilt my motor told me about this stuff and it worked really well for me. https://www.napaonline.com/en/p/NCB468913016

Forgot to add photos

The diameter is 2 5/8”
Thanks Tom

Tlitwin

I replacing the rear tires on my 26 touring. It has wire wheels. And see that one seal leaked pretty bad so was going to replace both outer seals. But should I also do the inner seals?
Thanks Tom

Tlitwin

I use Autolite 66. The are cheap and seem to work good for me. I buy mine at Auto Zone
Tom

Tlitwin

Thank you guys for saving my tool. I would never though the starter would draw over 50 amps
Tom

Tlitwin

Thank you, I can’t wait to see the current draw when using the electric starter

Tlitwin

I have this generator current tester. I’m not sure if it’s for T’s or how to use it. Any ideas?
Tom

Tlitwin

Scott, thanks for sharing your information. My car has always run rich and had issues with the float not wanting to always shut off the gas flow. I’m going to swap mine and see if it helps things
Tom

Tlitwin

Thanks Les, I just put new batteries in my analog voltage meter will try it when I get home later.

Tlitwin

I believe what I have in the photo is a tool for testing magneto voltage. But no matter which way I connect it the gauge goes down below zero. I was putting one end on the magneto output and grounding the other end. Car does run well on magneto. I was curious as to how much voltage it is putting out...

It’s a later model with center drain. It’s on a 26 touring.

Tlitwin

Thanks for all the advice. The links and Royce’s page convinced me to do one myself.

Tlitwin

How thick is the metal float for a NH center drain carburetor? .630 or .830 I also have two different sizes of float jets one has a .100 orifice and .375 outside diameter the other is .123 and .408 not sure which I should be using. If you were going to have someone rebuild your carb who would you us...

Thanks Mark

Anybody use Mac’s Radiator in Portland to have any work done to their T radiator?

Tlitwin

The car has a ruxstell rearend and rocky mtn brakes. Does that make any difference? If not I’m even more inclined to leave things alone. Drive the car this summer and pull the rearend this fall. As I’m just weeks away from finishing a complete engine/transmission rebuild. Thanks everyone for all the...

Tlitwin

Both the small and large are at the bottom with no extra capped holes on the top. Is it easier to undo the bolts by the u/joint housing and rotate or the bolts on the rearend? Either way the radius rods will have to be loosened and possibly removed. Or should I just drill a hole on the top. My plan ...

Tlitwin

They did not drill a hole for the grease cup. That’s what got me looking.
Thanks Mark

Tlitwin

I believe my u-joint housing was installed upside down. The grease fittings are on bottom and all the pictures I see show them on the top. What is correct. Should I just leave it alone? I have the engine out right now so it might the time to fix it, I think. Or is it hard to pull the housing off the...

Tlitwin

So I only use the small gasket

Tlitwin

Does the spray nozzle use 2 gaskets like in the photo

Thanks Tom

Tlitwin

I’m having my crankcase pan sandblasted. Is it ok to paint the inside when I paint the outside?
Thanks Tom

Tlitwin

John thanks for the help. I put a metal straight edge on my pan and it looks everywhere I check. I’ve attached a photo. Also what’s the width suppose to be from hole to at the mounting arms. This pan is 22” but the frame and old motor are 21.5”.

Tom

Tlitwin

Is there anyone around Portland Oregon that can align a crankshaft pan?
Tom

Tlitwin

I have 2 questions. I just pulled the motor out of my 26 touring yesterday. I’ve had it for 20 years and done minor work on it to keep it running but decided it was time to rebuild the engine and transmission. It was last done almost 60 years ago. And by the looks of the magneto it was the right tim...

Tlitwin

I’m thinking 1/4” to 3/8”.

Tlitwin

Any idea on the diameter?

Tlitwin

Do you have a picture of the magnets
