1970 FJ40 Hand Throttle (1 Viewer)

[Sparkman86]

I've scoured the webs and can't find what I'm looking for. Hoping a fellow 1970 owner can help. I have a 9/69 build that is mostly original. At some point, a 1974 F engine replaced the original. The carb on it when I purchased is an 04/70, so not sure if it's original, but there were some mods done with the accelerator cable and links that I've mostly managed to undo.

Where I'm stuck is with the hand throttle. I do not have the pedal stop bracket that includes the throttle cable clamp. My accelerator pedal was replaced at some point so not sure what originally came on the truck.

The hand throttle cable was routed into the engine bay right behind the block in the center of the firewall but not hooked up when I got it. The cable is almost 3ft long, too long to hook up in the cab, but I don't see where it would hook up to the carb. I can't find any pictures or diagrams that show a hand throttle connection in the engine bay. What am I missing?!

Can't find it because what you're looking for doesn't exist. The hand throttle never connects to carburetor, it's a short cable that connects to your existing pedal. The square opening on your pedal in the photo takes a body grommet that snaps in (easily found at a parts store or from Toyota). Cable just has a stop that rests on grommet, this never changed technically until about 1990 or so.

Only throttle linkage and choke cable connect to carb so the cable you have is actually a choke, I assume the graphic etched in the knob has a square with a / in it? Aka the logo for choke butterfly.

Definitely a hand throttle cable, but I don't believe this connected to the pedal (at peast not in the cab?). It seems way too long to hook up in the cab directly from the dash. I end up with excess cable splaying in different directions. The "typical" hand throttle cable is only 12-15" long or so, from what I can tell. This one is 30"+.

That pedal I have is a replacement. The eye had been bent around the rod to keep it out of the way. It's a definite possibility that the stopper bracket is not original either, since both pedal and accelerator cable were replaced, but I can't imagine someone swapping the hand throttle bracket, bending the pedal eye and running the hand cable through the firewall, just to not use it.

That looks more like a choke cable to me. Hand throttles that I have used had a lock to hold your setting. You had to twist the t knob to release it or push the center button in order to change the setting (never used one on a LC). On the accelerator cable was a special connection for the hand throttle that allowed the gas pedal to add more power if need, when you took your foot off it went back to the hand throttle setting..

I'd be looking in the factory manuals that covered PTO/winches which is where one would find hand throttles. I'd bet the LC museum or SOR has at least one rig with a hand throttle. Maybe you buy some pic's. @timmyisinthewell has the microfiche for like 69 to 83

100% an OEM hand throttle cable that measures in at 37" from knob to end. I cannot find another example of this cable though. No PTO from the factory on this truck, for what it's worth.

I'll check out that link, but I've searched every diagram and manual I can get my hands on trying to find this in a schematic or photo.

 

[Sparkman86]

I found this one on ebay that is similar style and length, but it has a looped end like you'd find on the vent cables. Mine has a curl to the end of the cable and very well could have been this exact one, but I see no diagrams or examples of how this would hook up.

What you have is a 9/66-7/70 Choke cable. Nothing more you need to know, that's why it is long. Why is it a choke cable? Let's analyze WHY.

1. Length (most obvious).
2. Hand throttles don't actuate the butterfly, they only pull on the pedal.
3. Land cruisers use a choke butterfly, which is what the symbol means.

Not keen to repeat myself but hand throttle cables do not enter the engine bay.

Correct, I can't find a listing for a hand throttle 10/69-10/71. Here is my 10/69 (70 model) dash. It has a chrome plug where a throttle knob would be. 10/71+ I show a bracket to mount the throttle to the bottom of the dash versus in it.

I know the pic quality isn't that good, but it's 50 year old technology and all I have. My eyesight is alot older than the technology used here, but that looks like a choke cable to me. Also note, I don't believe I see a throttle cable listed for the '70 year production, but I've been wrong before.

Appreciate the input, but I respectfully disagree. Choke cable is a different symbol. I am 99% confident this is the original hand throttle cable for the truck. This era choke and throttle cables have molded knobs that cannot be separated from the cable wire with destroying them.

I posted a pic of my choke cable below.

My dash is identical to this, with the exception that I have a throttle cable instead of the plug. Throttle cable is out of the truck in this photo but here is the choke and hole for throttle.

This is what is so puzzling. No schematics I can find list a throttle cable other than that short version in your pictures, but it is without a doubt, an OEM hand throttle cable.

 

[charliemeyer007]

When googled I see a lot of images/listing with a butterfly symbol as hand throttle, SOR has one with the THROTTLE which is what I would expect instead of what is often a choke symbol.

Ok - chase your tail, here is supporting documentation....I'm done here.

well, I finished up sorting out all the different PCV hoses and breathers and decided to dive into the next snake pit, the cables. I'm gonna look to @RAGINGMATT for the ultimate breakout list on these, as my last phone call with him made me keenly aware he's got this little niche mastered.

Wow. This is exactly what I needed. I appreciate your persistence here. Chasing my tail is the perfect phrase .

So by this thread, I have two different generation choke cables. The one in the dash now was pretty stiff and frozen when I took it out so my assumption now is that rather than cleaning up, the PO just added a second, later variation cable to use instead.

I'll gladly wear the egg on my face. Thanks all for the input! I was confidently incorrect.

Believe I found the problem. You have a 69 model not a 70.

Here is my 70 model I purchased from t the original owner.

That is original paint. Here is your FJ40.

70 model has a amber light on the aprons and red light in the back of the tub on the side. 68/69 model those were round reflectors.
Another difference is 70 models no longer had lights in the bib. Turn signal lamps were dual elements, second was for parking lights.

Yeah definitely a weird period for my exact build month. It's titled as a '70 model but VIN tag says 9/69 build.

I believe my puzzle has been solved. I have two variations of choke cable. The original and a later OEM version that was added where the throttle would have been.

 

[Sparkman86]

Maybe I'm not ready to concede this yet. I just stumbled across this very original, albeit restored, 1969 model with round amber reflectors and... a hand throttle. The knob symbol is very similar but definitely different than the "choke" variation in the linked thread above and in the listing. You can see both of these cables coming through the firewall in the center directly behind the engine block and heading toward the carb.

Sure looks like a hand throttle symbol, not a choke, to me.
