Cat 215 shut down

having trouble with throttle cable shut down of engine on my cat 215 serial 95z00480. I changed the cable because the end that connects to the injection pump was bent. Problem I am having is the throttle level will not push the injection pump lever up enough to shut down the machine. I can adjust it enough so that there is plenty of travel but it is just too hard to move the pump lever up enough. If I disconnect the cable and push pump lever up by hand it seems kind of hard to go and there is a hard click that it must overcome to shut of the fuel. The lever on the injection pump at low idle is at about 10-11 o'clock is this the right position for this lever? Maybe it should be at 8 o'clock for low idle so that the cable is at a better angle to push to over come the click of the pump? I think that the detent of the injection pump is too hard, or maybe it is not supposed to have a detent at all?
