Hydraulic parts

Spare parts for hydraulic pumps and motors

To maintain a fleet of hydraulic road construction equipment, you need to maintain the hydraulic system in a timely manner and periodically purchase spare parts for hydraulic pumps/hydraulic motors. Both units are similar in appearance, but their principle of operation is fundamentally different. A hydraulic pump converts mechanical energy into hydraulic energy, and a hydraulic motor, on the contrary, converts the kinetic energy of the hydraulic flow into mechanical energy, for example, to operate the actuators of machinery (bucket, hammer, crane, shovel, etc.).

Despite their long service life, hydraulic motors and hydraulic pumps require scheduled and routine maintenance over time. The service life of hydraulic equipment is reduced due to inadequate lubrication and the ingress of solid particles into the system. If uncharacteristic sounds and vibrations of hydraulic components are observed during the operation of the equipment, it is necessary to diagnose the equipment, based on which to determine which spare parts are needed for repair.

The most common breakdowns of hydraulic motors

The main causes of hydraulic motor malfunctions and methods of their elimination:

  1. The drive mechanism is malfunctioning. The cause of the breakdown may be wear or failure of the elements of the distribution unit, piston group, seals, shafts. During the repair work, the hydraulic motor is disassembled into components to measure the amount of wear, seals and piston group components are replaced.
  2. The shaft does not rotate or does not rotate evenly. The breakdown can occur due to "air" in the hydraulic system, mismatch of inlet pressure parameters, poor connection of the shaft and the actuator of the special equipment. The problem is solved by bleeding the air from the system, adjusting the pressure parameters in the hydraulic valve, eliminating shaft runout and jamming.
  3.     Overheating of the hydraulic motor. The probable cause may be improper operation or failure of cooling, the use of hydraulic fluid with a lower viscosity index, destruction or mechanical wear of component parts. The problem can be solved by restoring the cooling system to full operation, replacing the fluid, wearing components, or installing a new engine.
  4. Oil leakage. Lubricant leaks are observed due to loosening (insufficient tightening) of fasteners, wear of the cuff or shaft journal, and housing defects. To eliminate the leakage, we replace seals and seals, tighten fasteners, and restore metal surfaces.
The most common breakdowns of hydraulic pumps


The main causes of hydraulic pump breakdowns and how to fix them:

  1.     Unstable operation of the unit. It can be caused by wear of the seat or cradle, pistons, increased thrust gap of the control unit, contamination of the channel connecting the spool and the pump piston. It is necessary to disassemble the pump and determine the causes of its poor performance.
  2.     Reduced performance of the unit. Possible causes may include: wear of cylinders, drive shaft splines, bearings, piston bores, wear or damage to piston shoes. The worn part is rejected and then replaced.
  3.     Vibrations at low pressure. They can occur if the compensator pressure is incorrectly adjusted, the spool is broken, or the compensator circuit is malfunctioning. The issue is resolved by replacing worn parts and adjusting the hydraulic circuit.
  4.     Pump overheating. The possible cause of overheating of the unit may be a worn piston support, cylinder block, oil leakage through the safety valve. The problem is eliminated by replacing worn parts.
  5.     A characteristic noise. The breakdown may occur when the rotor group parts (bearings, pistons, cradle, cylinder block) are worn out, when a high viscosity index lubricant is filled, or when the shaft is not rotating properly. The problem is solved by replacing worn parts, replacing the hydraulic fluid with a less viscous one, and adjusting the shaft rotation.


After diagnosing and determining the list of replacement parts, you have 2 ways:

  •     Buy spare parts in our store and repair the hydraulic pump/hydraulic motor yourself.
  •     Use the repair service with full restoration of the unit to factory parameters by our hydraulic specialists.
