Tom and Don, thanks for the info. The collar is what is popping off when the throttle lever is pulled toward the firewall with the cable. The cable stays attached, but once the collar pops off, along with the spring, I am in trouble. The flange on the shaft appears to be in good shape. I will get that new collar! Appreciate it much! Steve

Steve, is the cable popping off of the link or or is the link popping off of the carburetor? If the link is popping off of the carburetor, you may not have the flanged end of the throttle shaft seated in the recess of the collar or the collar is worn. The flange on the shaft could also be worn.
Tom

Don, yes that is exactly what is happening. I suspected that the collar might be the problem, but it doesn't look like there was any abnormal-type wear on it. Are those collars available anywhere? Thanks Steve

Super et al: Your post that these were used on late 38-48 would be consistent with my observations. Question: I've seen 2-different foot-throttle ends, one that looks like a vitamin capsule (on early Fords) and one that looks more like a "bullet". The bullet design has a small "flange" similar to the rim on a 32 caliber round, that surrounds the control rod. These appear to be bigger than the early "capsule" design, which might explain the rubber ball-bushing. Problem with this logic is that we had an unmolested 35 Ford ton-and-a-half that used the "bullet" design. Anyone have any thoughts on this? Dan

Steve, if I understand your question, the hand throttle collar, spring and lever come off of the throttle shaft when you pull the cable. If that's the case, I would suspect that the collar itself might be the problem. It sounds like the detents in the collar that lock to the shaft are allowing the collar to slip around to the point where it falls off. The hand throttle is also pulling against the gas pedal spring if the pedal is not depressed. Try it with the gas pedal down to see if holds together. What you have pictured looks just like my '47.

The rubber ball covers were added in late '38 or early '39, thru '48. Check the metal ball ends on the throttle and choke levers, as some have sharp edges left from the stamping that will eat the rubber. A bit of filing may be in order.

Looks good. Just put a rubber ball over that ball in the picture and you're good to go. By the way; a rubber ball goes on the choke arm as well as both points of the accelerator linkage.

40Guy, I have all the pieces EXCEPT the rubber ball. Here is a picture with the throttle arm, spring (hidden under the retainer), and retainer. Thanks Steve

40 Guy: Thanks, I might also add that I grew up just a few miles from the Kaiser Steel Mill in Fontana (now the site of the Auto Club 500), so perhaps the smog ate all the little rubber balls! Rubber parts in SoCal would "petrify" in a matter of months. Dan
