Hey Guys another video to check out. I tore the rear axle apart and am curious why the gears make this sound.Its rolls with one washer, not with two and not 1 washer and one washer sanded down about 50%.
Im also in the process of trying to separate the drums. I need a breakdown image or Idea of where o start. The driven gear bushing is pretty scored up. I have a large list of parts I am ordering on monday . Any advice would be of help. Thanks again for all the feedback this year!

Send your triple gears to Dan MacEachern for needle bearings.

For sure you don't want to curse the inside of a T engine with a bunch of needle bearings. Wow that is a ridiculous idea!

The bushings work perfectly well so long as you do not fit them too tight!!!!!

I believe the noise will not exist if you lay the axle horizontal. When vertical the side gears on the axle set too deep in the spider gears and create the sound you are hearing. When under load the spider gears and axle gears move away from each other as far as the housing and thrust washers allow. Try laying the axle horizontal on the bench and apply some drag to the axles while turning the drive shaft/pinion and see if I might be starting out the week by being right about something. Good luck. Ken

Yeh, Royce, give us some examples of MacEachern triple gear bearing failures.

This tranny was overhauled by a pro, but using the soft triple gear bushings and odd sized pins that are available today:



One bushing was cooked, another loose in the gear, and the third one badly seized to the pin.
But it still ran..

Thanks Ken Ill try that. If I hear any noise like before Ill post a video. MY pins are in great shape, and I found a beautiful set of trip"s with new bushings for 70 bucks. NO needles necessary although I m not opposed to modern parts in certain places.

Ralph,

If you have shoddy workmanship failure is to be expected. Your transmission failed because the tolerances were too tight. The bushing seized to a pin.

Adding a thousand more useless parts to the inside of a T engine is not going to make it more reliable, faster, or better.

The gears sound ok and if the clutch disks do not look cracked they should be alright too. Not sure what the funny colour on them is though.

Trash the clutch disks. They're blue from heat and they're gonna fail. Make sure to test the clutch spring for tension. I think you want a minimum of 90 psi at 2 inches. I think!! Do you have the transmission book for reference?

The pin bearings in the triple gears impressed me when I first saw them. Then I pressed new pins in the flywheel, checked the clearances on my bushings and assembled. The extra expense for putting the bearings in didn't make sense. The photo of the triple gears with the ugliness is one case out of thousands. These cars have run 100 years with bushings. Just keep oil in motor/transmission and make sure your bushing clearances are good and your triple gears will probably fail long after your gone.

The book is on the way Mike, as well as a bunch of other stuff.

When you have half a day to spare, Mike, do a search on triple gear bushings. Many pros set them to .005, which was Ford's wearout clearance, to keep them from seizing.

I had a flywheel all set up with standard pins and bushings, then got Jersey George's high $$$ analysis, and pulled them back out in favor of Dan's setup. He says there are more than 100 carss running with his needle bearings and no complaints.
