thomastractorsvc Posted March 2, 2014 Share Posted March 2, 2014 if its not the linkage it is corrosion on the pin and peddle (Steel & Aluminum alloy), if you cant budge it may be time for a new one you can soak it with PB Blaster or your favorite juice but after that replace it don't know of many success stories with that kind of corrosion, without welding on a nut or heating, but that assembly you cant do it. Some boat guys I know say vinegar works, I have never tried that. I have had better luck just replacing those kind of parts. If it was a head or manifold I would try the heat method welding on a nut to a stud. Quote Robert"I reject your reality and substitute my own."

Superdog Posted March 2, 2014 Share Posted March 2, 2014 if it is the pin froze,like Rob said,you might as well replace it,I always end up breaking the pedestal trying to free them up. Make sure you put some never seize on the new pin. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/34869-stuck-gas-pedal/#findComment-235233 Share on other sites More sharing options...
BAD DOG Posted March 4, 2014 Share Posted March 4, 2014 Yeah usually you end up replacing the pedal. White Metal and steel frozen together. Pretty tough to heat and free up without melting away or breaking .

rsb502 Posted March 9, 2014 Share Posted March 9, 2014 Hell Watts has em in stock, I put a new one in mine just so the MACK lettering was crisp and clean. But I'm a little CDO, that's OCD alphabetically, the way it should be.
