    Cat 416 resolver question

    Was having loader issues. Would only raise when other function was used. Replaced bad seals in resolvers behind right rear tire. Now, loader will lift, but slow and only goes about halfway.

    John Deere 240D Hammer Hydraulic Lines

    The 240D is capable of 59 gpm. Ours is sat at 50. You can adjust flow to a certain extent to the cab. It is limited by the factory, however. (Will only go half way up). Just so happened, we remembered when it was installed on a Kobelco, the lines had to be crossed over as well. Thanks for all...

    John Deere 240D Hammer Hydraulic Lines

    The other hammer they were using quit, so we had this one rebuilt. Installed, it hit about 5 or 6 times then quit. If you hold the button down for a few seconds, it will slightly move down about an inch but won't move back up.

    John Deere 240D Hammer Hydraulic Lines

    Sitting in the cab, the left hose does move, doesn't seem to "jump" the right hose does not move at all. Some hammer outfit from up north rebuilt the hammer. It is a rammer hammer. It is nitrogen charged. There should just be only about 100 psi on the return right? My hydraulic pump is putting...
