No lift on 300 cx loader

[rjkiefel]

I have a JD 4105 w/300 cx loader. The lift stopped working ! It will go down and the bucket will still dump,but it won't go up. I checked hoses,connections,etc. no leaks. How do I go about finding the problem ?

Check the QD's for connection and flow.

Will the lift lever pull back at all?

Install a hyd pressure gage in the system and check the pressure.

Is the relief valve activating when you try to lift?

9 times out of 10 it's one of the QD's (quick disconnects) that cause these problems. Try unplugging all of them, then reconnecting them. Often they can look fully seated when they are not.
