I have a Mahindra 3325. The control valve in the hydraulics is sticking, which causes the 3 point lift to go up but not come down. I am replacing the hydraulic control valve assembly.
My problem is the following. In order to remove the old hydraulics control valve assembly, the linkage needs to be detached and removed with it. According to the service manual, to do this, a "cross tube" that is connected to the linkage needs to be removed. The cross tube is mounted to two pivots on either end of the tube inside the hydraulic lift housing. The question is: how do you remove the pivots for the cross tube? The service manual merely states that a special Mahindra tool is required. However, the parts deparment at the dealer has never heard of this (even when given the part number that is set forth in the service manual), and the service technician at the dealer states (over the telephone) that he does not use any special tools and believes he has used a flat wrench to remove the pivots. This does not make any sense... there are no nuts. The pivot connection can be seen on the outside of the hydraulic housing. I assume this connection extends inside the housing where the pivot extends inside the end of the cross tube. On the outside of the hydraulic housing, the pivot connection looks like a round plug or bushing with two small holes in it. I assume there is a way to insert something in the holes and unscrew the plug, but I am not sure it even unscrews. I am assuming this type of pivot connection is used on other tractors and other Mahindra models. Has anyone disassembled such a pivot connection?
