Hi all. I tried linking this message to an older post but it does not seem to show up so I thought I would retry.
Recently, I replaced the steering valve on my 1967 JD 5020 as it was leaking a lot. While it was out, I decided to rebuild the throttle mechanism and replaced components that had significant slack in them. I then went on to adjust the mechanism (according to the service manual) but noticed that there was a lot of play on the linkage on the injection pump, i.e.: the handle on the side of the pump has to move quite a bit (without significant change in RPMs) between low idle and shut off. As a result, I am unable to adjust the entire mechanism so that the tractor can be put at high RPMs and also be allowed to be shut off with the handle throttle.
The first question is: is this a problem with the lever on the side of the injection pump? If so, can it be adjusted? Is the problem somewhere else within the throttle mechanism. I have not had any problems with the pump and do not want to spend a $1000 on a new one. Please help. Thank you.
