Early 2 barrel big window F carburetor

[nuclearlemon]

Deja vu thread bump, one of these DD40/40 carbs just arrived in the mail to be rebuilt. I'll try to remember to take some pics.

if i ever get off my butt, i'll send you one to rebuild also
ideally, i'll find two aisan plates and one glass and send two to you

Been sitting on these with the intention of finding a 25 or 45lv to bolt up to... I've come to realize this isn't in the cards and will be focusing on my BJ42 project. Wanted to give 1st dibs to this section of mud before posting elsewhere.

2-Barrel 1F Carb & Intake/Exhaust Manifold

Toyota OEM

2-Barrel carb, Intake/Exhaust Manifold, and Oil Bath Air Cleaner Assembly...

Just realized, this is the very carb that was torn down & dropped in the ToxicTank (tm) today. Pics at 11.

A customer contacted me today, looking for a carb for a 1967. That's a transition year, with the ICS and PCV system coming online, and the upgrade to 12-port cyl head and 2-bbl manifold. So I said send me some pics of the engine bay so I can figure out what carb will work best.

See pics below. This is weird, to me. It is the early head, but it has one of the FA truck 2bbl manifolds. It does have PCV, so it's likely a 1967 USA engine.

I don't have another of the 1961-1969 DD40/40 2bbl carbs for the early 2bbl manifold.
Here's a question for the hive mind: Will a 1970 2bbl carb & aircleaner work on this engine? Is the manifold the right height and the right distance from head, will the aircleaner line up with carb?

@FJ40Jim

I took a few measurents of my 71 40. Not very scientific.
I believe the center of the front passenger side carb mounting stud to the machined mounting surface on the block is 48 or 49mm.

I believe the arrowed surface is the same height as the surface used to mount the air cleaner bracket.

I held a “relatively” flat paint stir stick on the surface.

Here you can see the bottom plane of paint stick is close proximity to the upper side of carb base.

Rested measuring device on top of riser gasket for photo. Taking into account gasket thickness, I’d say machined carb mounting surface of manifold is 25mm below machined surfaces on top of head that paint sick was placed on.

Holler if you would like any other measurements.

 

[FJ40Jim]

Thanks for measuring that!

Now we need the same measurements off the unobtainium 61-67 2bbl intake manifold:
1. Distance from manifold/ head mounting plane to an inner carb mounting stud. (this can be obtained by measuring the manifold)
2. vertical offset/height of carb mounting flange below the upper deck of head. (needs to be measured w/ mani on engine)

Anybody? Bueller? Bueller??

 

[thebigredrocker]

I wonder if @landcrusher909 still has his manifold he could bolt up to a block. Or pehaps @owensexport could get a height measurement off his firetruck.

@FJ40Jim

I believe the individual who sent that DD40 to you should still have the complete setup. I took some pictures of the manifold before selling it to them:

Here's the carb for Mcinnis' sweet 1959. What it looked like before teardown.

This carb & mani is off a 11/1965 Toyota FA truck. Date code 5 K 1 = 1965 Nov 1st, PN is 21100-60061 for FA truck.

Rebuild kit is a Keyster K11-029A, fits 2bbl FA truck carb, 1961-1969. This one was ordered from Sirius Carb Parts in Canada.

The throttles were all rusted solid, so had to be removed & cleaned up. There was the usual 50 years of corrosion inside. But it all eventually came apart and was found to be salvageable.

Going back together. Note that all the carbs before ~1973 are made of dead soft lead-zinc alloy. So the mating surfaces are always warped apart between boltholes, and the holes themselves always have thread partially pulled up above the surface. To fix this (and it has to be fixed) the parts have to pressed flatt-ish, then screw holes are countersunk, and finally the surface is flat filed to get closer to perfect. It's visible on the top of this carb body, but has also been done to sight glass area and bottom surface of carb bowl.

And a completed DD40/40 2 barrel carb for Toyota FA truck. Or a resto-mod 1959 Land Cruiser.

Great pix. Thank you, Jim.

Jim,

Thanks for photo-documenting this as well as the tech on warpage.

Hey, looking good. Has this shipped yet? No rush just checking in. Thanks, Mike

 

[FJ40Jim]

Took a while to get it on the test engine, but it did recently get test run & adjusted, and is now shipped.
Unlike the last one of these, it required no re-jetting.

Thanks for all the help. FA 25 coming at ya soon!

just picked up an F135 engine with one of these 2 barrel carbs, the manifold is cracked, hope i can get it welded up. it was from a 67' F6000 Toyota Truck like the one in pic.

 

[scoobiedubes]

I found one of these carbs recently, I have two of the FA intakes, one that I’m using on my 66 45LV with a sniper kit. The other one I might have to use with this carb on the 61 FJ25 FHT when I get around to working on it. Wonder how much more power you get out of that setup?

 

[ClemsonCruiser]

Cool carb but I’m not sure it’s a DD40. The top hat is different and the throttle bores look smaller. Wonder what it’s off of originally. Regardless beautiful Aisan face plate!

I don’t think it’s a DD40 either, was wondering if it’s from a RK / Stout or something of that era. There’s a plate on the top that seems to say PK30 but i wonder if it’s actually RK30, which would maybe make sense. Stamped 2C12 so I guess that’s March 12, 1962? Air cleaner setup may be an issue now that I think of it, probably need an adapter if the RK ones aren’t easy to find.

EDIT: Actually I think its a PK30 after all, which I didn't realize until now is the Toyopet Toyoace

I was following this carb on EBay and then realised it may not have enough power to pull an early Land Cruiser ”Tractor Motor”. Nice carb though..

I’m curious to find out. Reality is I’ll probably just steal the blue plate and put it into an SD40 that’s missing it though. But maybe I’ll play with it a bit first.

 

[ClemsonCruiser]

It definitely would be intriguing to see how it performed on your 25 or LV. I have a similar one I bought eons ago for the blue face plate. It has tiny bores so I wonder if it was off a passenger car. I’ll have to dig it out and see if it’s similar to yours. Bolt it on and see what happens
