    Default Jinma Hydraulic pump problem

    I have a hydraulic problem for my Jima 254. The end of the shaft (old style) does not engage the shaft on the hydraulic pump drive gear. The square end just spins inside the slotted area. Can the old style drive gear be replaced with the new style and then attach the new style hydraulic pump?

    Sounds like you need a new pump driver, there are 2- styles, you prob. need the longer one.

    We have the pump driver seperate or the complete assembly with gear and bearings,depends on how mechanical you are
