Understanding the Components

83012873
Before diving into the repair process, it’s crucial to understand the key components of a Sauer Danfoss hydraulic pump. These pumps typically consist of:
Pump Case: Houses internal components and contains hydraulic fluid.
Rotors and Vanes: Responsible for fluid movement within the pump.
Drive Shaft: Connects the pump to the power source.
Bearing Assembly: Supports the rotating parts and maintains alignment.
Seal: Prevents leaks of hydraulic fluid.
Identifying Common Issues
Common problems with Sauer Danfoss hydraulic pumps include:
Low Pressure: Often due to worn rotors or vanes, or leakage caused by damaged seals.
Unusual Noises: Can indicate bearing failure or misalignment.
Overheating: Typically caused by inadequate lubrication or excessive load on the pump.
Fluid Leaks: Often occur around seals and fittings.
Preparing for Repair
Before starting repairs, technicians should gather the necessary tools and materials, including:
Screwdrivers and wrenches
Torque wrench
Hydraulic fluid
Cleaning supplies
Replacement parts (seals, rotors, etc.)
Safety Precautions
Safety is paramount during repair. Technicians should ensure the hydraulic system is depressurized before beginning work. Wearing appropriate personal protective equipment (PPE), such as gloves and safety goggles, is also essential.
