This seal kit is designed to replace worn seals within the main hydraulic pump of Volvo excavators, ensuring proper fluid containment and pressure regulation. It is manufactured to meet stringent OEM standards, providing superior durability and sealing performance compared to degraded or damaged original seals. Operators may notice a loss of hydraulic power, external fluid leaks from the pump housing, or increased system noise when these seals begin to 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 sign of seal failure is often a slight decrease in hydraulic system responsiveness or minor external fluid seepage. If left unaddressed, the leaks will worsen, leading to significant hydraulic power loss and potential contamination of the hydraulic fluid. Continued operation with failing seals risks internal pump damage and costly repairs.
Ensure all mating surfaces are meticulously clean and free of any debris before installing new seals. Avoid using excessive force or sharp tools when seating the seals, as this can cause immediate damage.
Inspect the hydraulic pump shaft for wear or scoring, and consider replacing the hydraulic fluid and filter if contamination is suspected.
