 Topic: High Idle IH 460 Diesel
Posted: 23 Sep 2016 at 6:12pm |

I know it is the wrong color for this forum... LOL. But I am sure someone on here would know what is wrong or could help. Just recently the tractor started to idle higher than normal so I tried to adjust the injection pump idle screw but when you turn the screw it only turns the idle up. I also had the throttle linkage off and it made no difference so I am thinking its something inside the injection pump? Anyone else have this problem? Thanks Zach

the low idle screw is the small one coming out of the top cover at an angle, and should take a small allen wrench(3/32"), and a 5/16" wrench for the jam nut. Turn it in to increase, out to decrease. The screw on the lever is just a travel stop.

I tried turning both screws but the one your talking about on the top cover in an angle will not idle it any lower when I turn it out for some reason it only increases the idle.
