Are there any videos out there on what to do for the novice model 't' owner. Maybe some older links.

Bump. Kind of late maybe.

There's a whole bunch of information on Youtube and Smokestack.com on this subject.
I just spent a few minutes searching and found a lot.
Just search babbit bearing scraping and you'll be busy for a while.

Good luck, I'm in the same boat. I can't find a wide file.

i saw a video on scraping white metal bearings for a lathe on youtube but not engines. There is a valve grinding one i saw but they did not really explain spreading the paste in the valve.

Ted: You "draw file" the cap.

A long angle lathe file works great.

When, at the age of 16, in 1970, I first restored my Model T and I tore my engine down to rebuild it, I found that the top layer of my babbited bearings were all soft, grey and powdery. Back then, there was nobody locally, here in Florida who could babbit my beasrings and even if there were, there is no way I could have afforded it on my $1.65/hr. wage.

So I read up on it in my trusty Model T Service Manual and did what I had to, to make due. Using a long razor blade, I scraped down each bearing until I was down to good, solid, shiny babbit. I then smoothed the surfaces as best I could with fine sandpaper, wrapped around the crank shaft and seated in the block with cap attached, to get the correct curvature. Then, one bearing at a time, I fitted the bearing cap adding shims until the bearing was snug, then I added one shim. When all the bearings were fitted in this fashion, I put on the pulley and with the crank, ran the crankshaft in by hand until the crank turned freely. I must have done something right, because my Model T ran beautifully without knocks, for the next 38 years until my recent rebuild in which I was able to afford to send my block off to Connecticutt to have the babbits professionally re-poured by George King III using the original Ford babbit formula and genuine Ford equipment. I figure the method I used back in 1970 is probably how the average, dirt poor shade tree mechanic would have done it back in the day. Not exactly the most precise method, but sufficient for the very forgiving, Model T engine. Jim Patrick

Have you ever heard of common sense?
