TR2/3/3A The gas pedal linkage. This relates to my post about the throttle linkage issue I posted ......

[karls59tr]

but I am starting a new post because I need Information on the cross shaft that runs across the front of the firewall. In that post forum member 3798j was kind enough to post the factory schematic with the names of the parts involved. Has anyone taken the cross shaft off? The reason I ask is I believe I have a broken "Mils pin" that is causing the cross shaft to not move in synch with the firewall bracket leve r ..... the one closest to the rear carb. If I undo that firewall bracket will I be able to pull the cross shaft out or will I have to disassemble the driver's side bracket and lever? Any help here is most appreciated. Big trouble if a throttle jams at high speed.

I took mine apart and refitted it last year. You'll need to disconnect the springs, bracket, and linkage from the throttle connecting bar. also remove and refit the 2 bushings and housings on the left and right side of the bulkhead. It takes some fiddling and wiggling but it's doable. I cleaned up the white bushings, smoothed out the rough spots on the housing and the bushing with some fine sandpaper and lubed it with white lithium marine grease and it seems fine now. Replacement pins are easily available at Ace HW or Moss.

Thanks for the info. In your opinion is it possible for one of those mils pins to have sheared at the right side of the bulkhead causing the shaft to be loose and sometimes make the throttle stick? Then with a kick of the gas pedal it would release?

My experience is that the pin would not shear but rather the rod gets wallowed causing the slop.
I am attaching a pic of the TR3 linkage. It would be a 2 piece, but getting one of those pins out is very hard. Even off the car.

My TR3 experience: gas pedal linkage was getting caught on carpet, causing my throttle to stick partly open. Trimmed carpet at the trouble spot - problem solved.
