Are hand throttles rare?

[special-K]

It sounds like the lower end of you cable isn`t turning.Try cable lube or,first,PB Blaster to free it up.The rarest aspect of this set-up is the mechanism at the pedal.

i found one on a 68 custom camper cst in the bone yardi didn't take it because it looked cobeled on throtel linkage under the hood. after seeing the pic it may have been coreect. to bad some jack a$$ broke the dash bezel in to trying to get at somthing. i'll go back and get whats there. and a answer on the buddy buckets that if the other guy who asked a year ago didn;t get i could have for $75

called chevy duty (now classic auto) they had the knobs but discontinued the cables . So i took my throttle out of the cab and saw that you could take it apart from the back, so i got it apart after about an hour of persuading. The mechanism consists of two "little bullet shaped pointed metal things" with the other side open ended with springs that fit inside. These push into the grooves of the "screwlike thing" which causes it to turn outward or inward. The cable on mine is attached to the other end (no breaks) so i am blaming it on the grooves not being deep enough or worn, or the points on the "little bullet shaped pointed metal things" not being pointy enough and fitting into the grooves. Its probably a combination of the two because when i took it apart i made the springs stronger by stretching them a little bit and it made no differnce.

Tonight I'll try to get pics of the handle and handle shaft. My cable is not attatched, so I won't be able to get any pics of the OEM cable fastener, but would appreciate someone else doing so.

My father-in-law was telling me that he has several of this type of controller on the dash of his airplane. He said that the knobs have buttons in the middle. Push the button to release pressure on the threads and make course adjustments or turn to make fine adjustments.
Aircraft maybe another source for repair parts or non-OEM replacements.

My Dad had one on his '67 C-10 (6 cyc/3 on the Tree) he bought new in '67. I always thought it was neat. His truck didn't have a PTO or anything else special about it, just a plain jane '67 long fleetside wood bed 6 cyc/3 speed. No radio, no chrome, standard mirrors, with a hand throttle.

I took mine out of the truck and sold it. It was like having redneck cruise control. Kinda cool, but I really didn't need it

[MT1972cheyenne]

I had a 72 k-10 cheyenne that had one. I don't know why either. It was on the glove box tag. It did come off of a farm, but had no PTO. It was an automatic too.

I tried to repair mine like bucket said, but didn't have any luck keeping the "boss" on the cable after I got it small enought to fit into the handle shaft. I've since moved onto bigget things, but though the best way would be to tack weld a steel BB onto the end of the bicycle cable. Just haven't gotten it done yet.

if i remember right, i think i also enlarged the access hole in the side of the shaft by drilling it out so i could insert the boss.

To help with the sticky cable,remove it from the vehicle,clean it with WD or something similar,then just chuck it in the oil drain pan when full.Leave it to soak up oil and lube itself for a few days.I did it with a heater cable and it has lasted several years with no problem.

byrdman, does your "straight verticle piece" look like the loose bracket on the floor of my truck? Where does it mount?

bucket, mine turns okay under no load, but pops out of place when in use. Would a modified bicycle shift cable repair as you described fix this or do I have problems with the "drive" portion?

I believe this circled part here is where my cable is attached. But, my cable/handle is seized-up ,so I can not say for sure that this is the same cable (as some other cable may terminate here?).

[Aubigmac]

my 72 has one but it is mounted on the left side below the headlight switch. Never has worked but if it is this unique I might have to try getting i back in when I rebuild the truck.

Does everyone elses label that says Throttle look like it's added after the fact at the dealer?

It is just a nameplate that sets over the threaded part of that knob assembly and gets sandwiched in there when the knob is mounted to the dash bezel.

I think the one I just bought might have that same "popping" issue described earlier. I really won't be able to tell if it will work right until I install it.

Now I have a question: Does anyone know where the cable bracket inside the cab goes? My setup came with another bracket and I haven't seen a picture of it installed anywhere.

mine "pops" out of place if i don't apply pressure to the gas pedal while turning the knob. once in place, it does not slip back, however. i'm not sure the new cable would help. you might check to see that the outer housing that the knob threads into has not split apart.

Would anyone on here be willing to sell or know someone who would sell their throttle name plate? Mine has long since been lost, and I took it off so nothing would happen to it...go figure.

I believe uncommon and rare are the same thing. If it is uncommon that makes it rare.

My 70 GMC K15 has one, bought it from a farmer/rancher, It works.
