59AB Going into my '33 Truck, Generator Question

['32FordNut]

Good Evening, I finished my '32 water pumps and now I'm moving back to my engine swap on my truck. I'm taking the 4 banger out and putting in a 42-48 59AB. Does anyone know what generator, fan and bracket system I can use??

I have half the people telling me to put the generator/fan on the intake manifold and the other half saying the generator mounts on the manifold and then a drop down bracket with the fan and hub mounted on that. I have a stock radiator if that helps. Can I use the generator/fan on the manifold or do I need the drop down bracket with the fan & hub, that's the question boiled down, which setup? Thanks again for any help. Jeff

Use a gen with a fan on it, either a 33-8 w/cutout out 39 with voltage reg. Yes, it mounts on the manifold. You will need to use a 33/4 fan because it has the correct spacer on it.

Thank you Jim, If I use the generator with the fan on it, I will need to change the crank pulley to just one instead of a double, correct. The crank, fan & water pumps will all run on just one belt, correct? Thank you for your help!!

I'm setup right now with 2 pulleys and the drop down. A friend of mine gave me the bad news and said that was wrong for the 33 truck. That's when it started, it was 50/50 with everyone's opinion, but the friend of mine who told me is an expert on 33/34's, however has never done a truck. He also told me that I'll probably never find the correct generator & fan since he hasn't seen one in years around here in CA at swap meets. Any suggestions to locate one? Thanks again, Jeff

What transmission and rear end are you planning to run? The original 33-34 Ford 4cyl pickups torque tube and driveshaft are not the same length as the V8.

I found that out also after 50% were telling me it'll bolt right up and the others saying it's about 1-1/2" short between the 4 banger and the V8. So I have a longer driveshaft and tube that I already bought. I'm running a '39 trans with the stock rear end that has 3.73 (?) gears. The gears are definitely not 4.11's. I have 4.11's on all my '32's except my 3-W and it has a Columbia. I hate 4.11's in the LA area and 4 bangers. LOL

Thanks for the heads up on the driveshaft, I appreciate your input.

Sheldon is correct! All (not just pick-ups) '33 & '34 4-CYLINDER driveshafts and torque tubes are 1-1/2" SHORTER than the V8 tubes and shafts. The difference seen BELOW!

33-34's did not have 3.78 UNLESS it was changed out with 35-37 3.78 10 spline gear set.Machining is required to do that. 4.11 and 3.54 were the only gear sets in 33-34.If you have the 33-34 rear look on the bottom side web of the banjo center section and see what numbers are stamped .

The generator '39 Standard type with the fan mount can be found on the 'Barn'. Newc

Yes (to Sheldon's post #7), and as he is aware, I put the 3.78 gears in my 33-34. In my opinion, I got lucky, as I was really happy with those gears. (36LB engine, and living in the mountains.) As to the original generator question, I used the 33-34 generator with fan on it. Not much room in there, and the 33-34 stuff fits. I'm doubtful about room for the later 'drop-down' arrangement (although I never tried it).

['32FordNut]

Thank you all. Coop, wow that is some trick things that were fabricated. I wish I knew just a fraction of what y'all know. The engine I'm putting in is a 59AB from a friend of mine that had it in his 1936 Ford Pickup. He gave it to me when he screwed up a piston. I had it all machined, sleeved and rebuilt, I think .30-.40 over. I think it is a 42-48 engine with the crab type distributor. He kept the generator setup that he used on his new motor that he put in. So I'm just not that smart with experience to know exactly what year the motor is. I do know the oil pan is from a 1-1/2 ton or bigger truck, because it's the 2 piece one and the smaller part is missing. So I have some problems. But I want that 4 banger out of there and this new engine put in so I can have some fun with it. No offense, I have no fun in 4 cylinders, and they leak like crazy!!

Thanks Sheldon!! I'm going to look and see if there are any numbers stamped on that rear end. I bought 3 cars from a friend of mine when he dies and they let me have first choice. I bought his 2 '32 Roadsters and this '33 Truck. He was a lakes racer and has several records, so if the rear end needed any machining or work, he would have done that with no problem. His name was Harold Johannsen if that rings any bells. He setup all his cars with down draft carbs, adjustable valves, pressure oil pumps, etc. Thankfully, the 2 roadsters are V8's, LOL.

Newc, will the '39 generator fit on my early '33 truck? I think BobH said I should use the early (33-34) generator, that fits in with the room. I do have a friend that has a setup that is off his 59A but it's from 1947 he said. That sits on the manifold with no drop down bracket.

[bobH]

I 'schemed' on how to use a 47 generator. Never came up with a satisfactory way to mount the fan. However, having said that, I believe I read somewhere (probably here) that 'someone', maybe Charlie, came up with the necessary machine work to use a gen-mounted fan. It's been quite awhile, and my memory aint great, so not sure of that. (And, be careful with the 47 gen.... pretty sure it's a screw-on pulley. Might want to unscrew??) Someone here will know more than I can remember....

[Bored&Stroked]

You should be able to use the early generator - 3 brush - that has the front fan mount pulley. I believe all of these used a cutout instead of a voltage regulator, not sure if that can be changed or not?

[deuce lover]

The 39 "Standard" generator is a 2 brush and has the fan mount pulley.It should work fine with your combination.You will need a 33-36 fan.Those generators are tough to find. The ones I had I sent to Whitney & Co in Fullerton for the alternator conversion.They offer the alt conversion for all those early V8 generators. Since you are putting a later flathead in the '33 chassis you will need the "U" shaped spacer for the front motor mount support
Like these on EBAY now.

[jimTN]

You also can hacksaw the extra pulley from the later double pully so you will have clearance with the crossmember. If I remember correct, you can also switch bearings in the front of a later gen, roller to thrust bearing and that will make the later gen usable. If you have a screw on pulley, it should have a circlip on the outside of your pulley after it is installed to keep the pulley from unscrewing.

Deuce lover's comment in #15 is correct about a '39 generator, however, the comment about the needing '49-50 Merc water pump mount adapters on a 59AB installation into a EFV8 is wrong.. The '49-50 Mercs adapters are only required on the 8BA/8CM engines, 49-53.
I converted the generator on my '36 from a three brush shunt, to a 39 two brush w/ regulator in '52. The '39-48 generators are basically the same except for the pulley, which has provisions for the fan blade to mount to the front of the generator with 4, 1/4" bolts.
I think it should be pretty simple to remove the outer pulley from the pulley, quite often the second pulley is bolted to the assembly.

Only the '49-'51 Mercs had the "ear" motor mounts on the side. The rest of the 8BA series engines had the mounting surface mounted at an angle on the bottom of the water pump. Also, there is a difference in the motor mount heights between the '32-'40' cars and the '41-'48 cars. Hurst sold adapters specifically for this use. Their front mounts bolt directly to the frame in the later cars, but they recommended spacers for the early cars. Since the Hurst series 202 mounts are an exact analog of the front mounting geometry of the later cars, it stands to reason that the 59A needs the spacers as well (item # SP-150 in the attached diagram). Whether these spaces are the same as the 8CM units escapes me at the moment.

[deuce lover]

Blucar.With all due respect.Were talking about the 59A,not the 8BA.That what was on the 59A in my 34 Vic in 1968.A friend just installed a 59A in his '33 roadster here and he made his own rather than order from US.Been there and done that one.

[bobH]

A little more, with regard to posts 17 and 18.... The 'spacing' in the 33 chassis is different, compared to the spacing of motor mount holes for, say, 37-48 (or 53). So, those U-shaped brackets account for the difference of width of the motor mount holes. Those brackets were originally a Ford part, listed in the green bible, intended for use when putting a later engine in an early chassis. Look up part number 41A-6023, on page 223, in the green bible. Intended for installation of later engine in 33-34 chassis. (Note that I'm NOT saying that this is the way to do it. And, it's NOT the way I did it in my own cars. Just sayin...)

Couple brackets from my stash... tried to show the offset of the holes. Same as what Sheldon posted, above...
