If you are willing to ship it, I'll buy it from you?
You can PM me to make arrangements.
I'm wondering what's the combo you used between the motor/transmission? Fly wheel, pressure plate, clutch and release bearing.
Thanks Manyolcars for this awesome post!
Thank you Departed. Those are the pictures I've been waiting to see. Cross member clearance with the 4 speed.
I might have to cut part of the lip off the side of the cross member for assembly. I can assemble it by lifting the front of the motor (lowers the tail end) and have enough clearance to put the torque tube and clam shell together. However, this may cause problems later down the road if I want to take it apart once the body is on top.
I will cut a little at a time to make sure I take as little as possible to be able to put the clam shell assembly together.
I'm glad you guys are using the information. Just wait until you drive it!! A bone stock A engine with this transmission will run off and leave a hopped up A with stock transmission just because you can shift so quickly
Can't wait to try it !
Manyolcars, did you use the AA pressure plate ? I don't seem to have room for the A throwout bearing.
You will need a V8 type thrust bearing carrier ,,they are a lot shorter,,it will work with your A bearing ,,and fits your forks ,,
I used the Model A pressure plate and the AA throwout bearing carrier because its shorter
Where can I find one ? I'm trying to find a AA bearing carrier but don't seem like anyone sells them.
Maybe they're the same as the V8 ones ?
The V8 type is what I used and I had a good A bearing ,,stick a wanted ad on and see how you go ,,
I must be able to buy a new V8 bearing carrier online ?
Don’t know if you can get a new one but someone would have one laying around surely,,they would be the same from 32-48 at the least ,,I’ve had good results from wanted ads ,,try the F/B Model A site or the HAMB ads ,,,
Per the fitment chart, this looks like the part needed........I think. https://www.macsautoparts.com/ford_...senger-except-37-39-60-hp.html#tabs-container If it is, $24.79 is reasonable enough.
That’s it ,,good price alright,,,
Who did your splines? Looks clean. Did they have to anneal it and re harden it? I’m not overly happy with the machine work on mine. And only half the splined end is hardened ...... might have to find another shaft and start over :-/
Except avoid Macs.
Moser Engineering did mine.
How does the u-joint fit? Did he anneal the shaft to cut the splines ?
U-joint fits nice an snug. Don't believe they annealed it. It is turned down and cut in a blank area of the shaft that may not have been hardened originally. I honestly don't know. But it fits really good and I know other guys that have had them spline theirs and have had no issues.
Whether the shaft was annealed or not, I don't believe any Model A engine ever built could hurt any part of that transmission. It is basically the same transmission as the top loader 4 speed that did duty in Fords all through the muscle car era of the 60s and 70s. The overdrive transmissions use different ratios and different shifting mechanisms, but the gears and shafts are mostly all interchangeable. The overdrive cases have a bulge in the side to accommodate the big gear on the counter shaft for the overdrive ratio, so those gears won't fit in a 4 speed case. However, the 4 speed gears and shafts should all fit the overdrive case. I've read that some of the lighter duty applications used a smaller bearing where the tail shaft goes through the case, but no Model A or B engine should be able to hurt any of it.
Drive it like you stole it.
The overdrive gear train does fit in the regular four speed case with a few modifications, oddly enough the big overdrive gear doesn't hit the non-bulged case.
I did this conversion many years ago (pre interweb) before I knew of the existence of the "Toploader Imposter".
I did have to relieve the reverse shaft support part of the case to clear the second biggest gear on the countershaft, however, and make a thicker thrust washer for the reverse sliding gear, plus a few smaller alterations.
So there is a bit of machine work involved with the conversion.
That's good news, that the overdrive gear set will fit. I'm gathering parts now to put the Jeep version of the 4 speed transmission in a 29 Tudor. I think the Jeep version is a T-176 if I remember correctly. It already has a very short output shaft to couple with the transfer case and a top shift cover. If I decide sometime that I need overdrive I could just swap in the gears. Shift pattern would be weird is all, I think.
I've rounded up 3 of the Jeep transmissions. One of them was just the case sticking out of a bucket in the back of a pickup sitting in front of me at a stop light, haha. I followed the guy and found out that he had broken the reverse slider gear speed shifting as fast as he could forward to reverse when he was stuck in a mud hole. The transmission shop that took it apart to see what was wrong sold him a granny gear pickup 4 speed to stand his abuse. I got the broken one in pieces for 20 bucks.... he even threw in the bucket, haha. Occasionally my lucky stars fall into alignment.
I ended up ditching the banger and adapted my shortened 3 speed trans to a Mercruiser 4 via a steel scattersheild ,,been running around for a couple of months now ,,works well ,,looks original underneath to fool the experts ,,
Nice job Roddy. Is that an aluminum case or grey paint?
Thanks Fabber it’s grey paint on a Lakewood steel scattersheild with the stock type mounts added ,,the front radius rod mount also mounted underneath
The T176 transmission has a 3.52 to 1 first gear, compared to a regular Ford toploader of 2.78.
So you could use numerically lower rear end gears to give you a "normal" first gear, while giving a low rpm highway high gear.
I don't recall what type of differential you are using, but if an 8 or 9 inch, that means you could use the super low number highway gears (2.50 or 2.79) and still have decent ratios in the lower gears, in other words the car would drive as if it had an overdrive transmission.
Thanks Fabber it’s grey paint on a Lakewood steel scattersheild with the stock type mounts added ,,the front radius rod mount also mounted underneath so it all looks stock
