need help with SBC to `39 ford transmission

i took on a quick project between other stuff and have run into a snag , and i need to get this in today. i have all the correct parts, pressure plate , disc,etc....except the pilot bearing adapter , which is in transit..i was told it would ship on monday , but shipped yesterday ...i can't wait for it

i'm hoping someone has one and can take some accurate measurements and pm them to me so i can make one...it's speedway part number 720-5000

if not, i will just have to figure out what it needs to be , but it would be nice to know if what i make is correct

i've looked on their website and there are no dimensions , i also checked wilcap's with same results

thanks for any help you can provide

 

Well here's a good starting point.

I have one here and it measures 1.394 in length, 1.094 o.d., and .667 on the I.D.

I would measure the snout of the input shaft for the most accurate measurement if you are making it yourself that goes for tho O.D. also if the crank hole is right there.

I'm thinking the overall length would be the measuremenent in question here.

I actually have two here and the one has nerl on it but it matches the od of the newer one. But.....the overall length on the nerled one is 1.435

Hope this helps.

 

I had a brand new spare.........but I sold it to Continental John....he may not have installed it yet

I went to the bearing supply place and done some research and found a roller bearing. I will look today and see if I still have the number. I gave a bunch of recipts from the 40 to the new owner......

He types faster than I do......

thanks all for the help , that is about what i came up with that would be needed , except i measured the end of the input shaft on the ****** and came up with .657 , .667 would give 10 thousands clearance which might be a little too big

 

I went to the local Parts store (NOT AUTOZONE) go somewhere That still has a partsman and get a stepped pilot bearing for a chevy and drill the center out to fit your input shaft. I drilled mine where it was a little loose so it would slide in and out without sticking. It was made by Dorman but I dont have the number handy I can get it for you if you cant find it.

 

I might be wrong here, but I'm pretty sure Henry used standard ball bearings for his clutch spigots. Standard bearings are...wait for this... METRIC!
The stock Ford Spigot bearing has a 17mm bore, which equates to.669" .
Hope this helps.

The bushing I got from deuce roadster is a speedway part # 720-5000 and she does have a bit of slop .012 .. I can make you a tighter one if needed

thanks John

 

thanks for the offer,but i did manage to get one made . the motor/****** is in .

apparantly the transmision input shaft i measured at .657 has a lot of wear , i checked another and it measured .669....i had no idea that there could be that much wear

my main concern was the overall length, to make sure enuff of it is pressed into the end of the crank , and the other end make full contact with the ****** input shaft...i have .750 in the end of the crankshaft, like a stock chevy pilot bearing , and an overall length of 1.510


thank you all for your help , with your ***istance and a little measuring i was able to get r done
