throttle linkage

[ptmoore]

Howdy fellow smokers, having recently aquired a 92, one of the first things i did was to replace the plastic ends on the rod to the pump with the new metal ends. while adjusting the rod lengh is it ok to take up the slack in the eccentric that the pump arm goes thru. this rod is centered in the eccentric by a wishbone type spring.

You shouldn't have any play in the spring- pin area. If you do, look carefully at the pins that the spring hits, they are known to wear. Springs wear and the tip breaks off, letting the arm move in the slot before the actual throttle moves. I replaced my spring recently, tip was broken. Then I brazed up the pins, they cost $40 to $50 for the arms. The spring was about $15. I reset the linkage, big difference!

do not have another 1st gen to look at, are you saying there is more than one pin that the spring contacts?

Yup! I bet one of yours wore thru and broke off. If you look on the 2nd page of the governor spring sticky in this forum there is a good picture at the top of the page. There is a round pin and a square pin, round on the bottom arm and the square on the top one. The spring holds them together and acts as a safety so you don't over torque the pump guts. If you take it apart to go get one, watch the index marks on the shaft and arm. I didn't take mine with me and I got an arm that was a little different. My arm wasn't broken, just worn, so I filled the hole with braze and took the other one back. Good luck!

cheap fix

A cheap fix that I do when the spring starts to wear too much for comfort is,

to take a piece of brake tubing and slide it over the ends of the spring that are worn... It works for quite a while if the spring is not worn more than half way threw..... another thing that you need to remember is that if you remove the arm on the pump it needs to go back exactly in the same clock position on the shaft... there are marks on the parts for reference... ... .



another problem is the bushings and pivot shaft the throttle cable go to...

I normally replace the pin with a hardened dowel pin and ream out the bushing tube to fit it..... I grind the flats on the pin then heat the end with a torch just at the end... then I put the arm down over the flats and pean the shaft over like a rivet till the arm is tight to the pin... . I also put a grease fitting on it...



I did make one for my truck once where I used small roller bearings. . It worked great but it took about 4 hours to make up all the parts... . we engineers can get carried away at times if we do not have a bean counter telling us how to do our job. LOLA
