Shanghai -50 tractor hydraulic pump removed from the shell when the best program

1) Use a 35L container to let out the oil in the rear axle housing while still hot. 2) If the control valve is in the raised position lift the lift cover and pad a 40 mm thick pad between the covers to force the lift arm to fall and allow the oil in the cylinder to drain from the lower end of the upright pipe. 3) Lift down the hydraulic lift cover, it is best to twist the head of the hydraulic cylinder at the wire sleeve, in order to facilitate the lift. 4) Remove the limit retainer on the transmission gear shaft, slide the coupling forward, together with the transmission gear shaft, out of the high and low gear sets. In taking the limit retainer, you can pry one end out of the slot to push the locomotive forward or backward, pry up the card spring can be prized with the rotation of the drive shaft. 5) Move the lever forward, so that the high and low fork to move backward to the low gear position. At this point can be easily loosen Ning bit screws, remove the fork and high gear gear. 6) Put the PTO shaft control handle in the middle to swing the neutral gear, make the transmission gear spline hole and the spline of the hydraulic pump eccentric shaft completely disengage. 7) In order to remove the PTO shaft guard (or joint sleeve, drive pulley) and the bearing pressure ring, and then use two M10 × 50 screws for the top wire, the top back to move the bearing 60309 and power Output shaft, until the front end of the power take-off shaft support shaft from the eccentric shaft offset hydraulic pump some distance. 8) Pull the eccentric handle of the hydraulic pump to the disengaged position to move the inner spline clutch on the power output shaft of the transmission forward, and separate the spline from the front of the hydraulic pump. 9) Remove the screws on both sides of the rear axle hydraulic pump pin seat, and then remove the positioning pin on both sides, the hydraulic pump is in a floating state. 10) The hydraulic pump assembly moved backwards, so that the hydraulic pump eccentric shaft bore and power output shaft back bearing journal completely disconnected. 11) Flip up the hydraulic pump, the hydraulic pump from the horizontal state into a vertical state, you can smoothly put forward.
