Rexroth Pump Repair Removal Step Method

How to repair it? How to disassemble? Such problems usually arise in laymen or people who have just started their careers. Hydraulic pumps will wear out for a long time or there are material blockages to replace hydraulic oil and other series of small failures, of course, Rexroth liquid music pumps are no exception. Some problems with rexroth pump can be solved by disassembling and cleaning and then installing back, and the rexroth pump after reinstallation can be used normally for a long time, but there are many customers who disassemble and will not install it back, or the installation is not in place to cause potential damage to the rexroth hydraulic pump, for this reason Elephant Fluid Power will introduce the relevant steps in detail for everyone, so that everyone can better pay attention to some details to avoid secondary damage to the device. Pay attention to the following details can perfectly save some repair costs.


Rexroth hydraulic pump maintenance has many situations, in general, can be divided into two categories, namely pump maintenance and pump maintenance. Compared with the maintenance inside the pump, the failure outside the pump is undoubtedly much simpler. To many hydraulic pump failures are outside the pump, such as some to the lack of oil, pipeline leakage and so on caused by noise or pressure leakage. This can all be solved by external maintenance of the pump. We can add hydraulic oil to the cylinder, replace the oil supply pipeline and the oil control valve, etc., without disassembling the hydraulic pump, you can solve the problem. This kind of hydraulic pump repair is usually simple, we call it hydraulic pump pump external repair.


As for the maintenance of the pump, there are many factors, and basically every failure situation may be the internal cause of the hydraulic pump. In this case, we need to speculate on the cause of the failure according to the hydraulic pump failure phenomenon, find the root cause of the failure, and carry out targeted repair for its cause, generally first need to disassemble the pump body, the steps are as follows:


Step 1: Disassemble the controls

Step 2: Disassemble the oil supply pump (Note: mark the assembly position)

Step 3: Disassemble the main body of the pump

1. Mark the position of the hexagon bolt

(1) Record the position where the bolt should be screwed to

(2) Screw the hexagon bolt to the marked position

2. Make a mark and remove the rear cover (connection block) of the rexroth hydraulic pump

3. Remove the rear cap and oil dispensing tray

(1) Press down the cylinder block

(2) Remove the fixed hexagon snail

(3) Remove the rotary assembly

Note: Do not scratch the surface of the rexroth hydraulic pump cylinder body Note: Do not scratch the cylinder block

4. Remove the cylinder block and plunger from the surface

5. Use the self-tapping nut to screw into the part that is not closed by the metal (2 places) and then use the vise to pull the seal out

6. Use a soft hammer or copper rod to gently knock the shaft out

7. Remove the rocking disc and bearing

8. Take out the positioning pin of the swashplate bearing of the rexroth hydraulic pump


The important reminder here is that because there are too many things involved in the maintenance of the pump, a hydraulic pump or a hydraulic system, the parts contained in it are all contacted by the maintenance of the pump. Therefore, in the absence of a very clear understanding of the hydraulic pump or hydraulic system, Elephant Fluid Power recommends that you do not disassemble the hydraulic pump and repair it. If there is a deviation in the middle, the later use may make the entire hydraulic pump scrapped.


If the hydraulic pump can not solve the situation on its own, it is best to contact the professionals, let the professionals come to solve, and put an end to the hidden dangers of the project!
