Coenut Posted July 26, 2015 Share Posted July 26, 2015 Hi guys, my f model has a 237 and a 5 speed. While up shifting the truck bucks horribly. I only bobtail. I have lubed all the linkage ,checked the throttle springs, changed the filters, checked for Bent or broken link rods, changed the air filter, replaced all fuel lines. I even go easy on the throttle so it will run smoother. It kinda seems like a fuel delay. Any thoughts.

41chevy Posted July 26, 2015 Share Posted July 26, 2015 Wonder if it's not fuel but, clutch chatter from weak or broken spring on the disk(s).

b61mack Posted July 26, 2015 Share Posted July 26, 2015 I would say governor springs getting weak in the pump. Quote Link to comment https://www.bigmacktrucks.com/topic/41083-tractor-bucks-badly-while-upshifting/#findComment-297893 Share on other sites More sharing options...

Coenut Posted July 26, 2015 Author Share Posted July 26, 2015 I was thinking something in the pump was weak or malfunctioning. Quote Link to comment https://www.bigmacktrucks.com/topic/41083-tractor-bucks-badly-while-upshifting/#findComment-297918 Share on other sites More sharing options...
Coenut Posted July 26, 2015 Author Share Posted July 26, 2015 I also had a lot of algae in the tanks when I bought it. Quote Link to comment https://www.bigmacktrucks.com/topic/41083-tractor-bucks-badly-while-upshifting/#findComment-297919 Share on other sites More sharing options...
