Whiskymack Posted April 24, 2015 Share Posted April 24, 2015 Can anyone tell me how the throttle linkage works on an R model? I'm building a scale model Valueliner but cant work out the route of the cable. Seeing as the fuelpump is on the right hand side and the throttle pedal is on the left and there's not a whole lot of space in front of the firewall, I'm guessing that the cable must snake from left to right under the cab and emerge on the right hand side of the engine block before connecting with the back of the fuel pump. Is this right? Quote Link to comment https://www.bigmacktrucks.com/topic/39797-r-model-throttle-linkage/ Share on other sites More sharing options...
jakebrake86 Posted April 24, 2015 Share Posted April 24, 2015 There's a linkage rod on roller bearings mounted to the back of the motor. The pedal pushes a rod that rolls the cross rod, and another works the governor on the pump.

jakebrake86 Posted April 24, 2015 Share Posted April 24, 2015 I guess I need to look on my value liner, it may be mounted to the cab too, I can't remember. 1 Quote Jake Link to comment https://www.bigmacktrucks.com/topic/39797-r-model-throttle-linkage/#findComment-287704 Share on other sites More sharing options...
