The round pedal screws onto the starter pedal shaft on the cab floor. An additional set screw keeps the pedal from unscrewing from the shaft.
Does anyone know what the thread pitch, diameter and length of that set screw is?
Thanks.

It should have a back up nut to lock it. | | | | | Joined: Sep 2001 Posts: 29,269 Bubba - Curmudgeon | | Bubba - Curmudgeon Joined: Sep 2001 Posts: 29,269 | | | | | | Joined: Jan 2001 Posts: 1,422 ODSS President | | ODSS President Joined: Jan 2001 Posts: 1,422 | I've never seen one with a set screw.

It's weird because there are threads for a set screw in the cap of the pedal with maybe a 1/4" depth. The reason I ask is because I occasionally have to keep tightening the pedal on after a few months of driving. | | | | | Joined: Sep 2004 Posts: 241 'Bolter | | 'Bolter Joined: Sep 2004 Posts: 241 | It goes right into the center of the button (2012) in Tim's link. | | | | | Joined: Apr 2005 Posts: 7,440 Bolter | | Bolter Joined: Apr 2005 Posts: 7,440 | Take it off and go to your local bolt/nut supplier and find one to fit.
