555d starting problem

[jim770]

we have a ford 555d ,it cranks over fast for a 3-4 revs and then slows down and won't start I believe it in the hyd. system m mainly because the loader will jump after a few try's could the loader valve have a problem and ahs any one had this problem be for thank you in advance

By what you are saying it appears the hydraulics are engaged,go around every lever and make sure they are all returning to neutral and feel right,if the hoe is trying to jump a lever must be stuck,look at the top of the valve chest you will see where the levers connects to the spools they should be all about the same height,if it's got a low or high one check it's movement,how did this happen?.

Had that happen on a Case 680 years ago, would start then die right away. Owner finally found one of the hydraulic levers locked in detent by his grandson over a weekend visit..
