This is a hydraulic pump sealing component, often referred to as a seal kit or gasket, designed for specific Volvo excavator hydraulic pumps. It is manufactured to precise tolerances using durable sealing materials to prevent internal and external leaks, ensuring optimal hydraulic system performance. Operators may experience a loss of hydraulic pressure, external fluid leaks from the pump housing, or a reduction in overall hydraulic system efficiency when these seals fail.
Always verify with serial number before ordering.

Flush hydraulic lines before fitting new components. Use only manufacturer-specified hydraulic fluid. Check O-rings and backup rings for correct orientation. Bleed air from system after installation.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
The first indication of failing hydraulic pump seals is often a noticeable external hydraulic fluid leak from the pump housing. If ignored, these leaks will increase, potentially leading to a significant loss of hydraulic pressure and reduced machine performance. Continued operation with leaking seals can lead to pump damage and contamination of the entire hydraulic system.
Ensure all sealing surfaces on the pump housing and shaft are meticulously cleaned and free of any burrs or imperfections before installing the new seals. Do not use excessive force or pry tools when fitting the seals, as this can easily damage them.
It is highly recommended to replace the hydraulic filter and inspect the hydraulic fluid for contamination when servicing the hydraulic pump seals.
