This is a hydraulic pump seal kit designed to prevent fluid leakage and maintain system pressure within the hydraulic circuit of Volvo excavators. It is manufactured to meet stringent Volvo quality standards, ensuring superior sealing performance compared to worn or damaged seals. Failure of these seals can manifest as external hydraulic fluid leaks, a spongy or slow hydraulic response, and potential overheating of the hydraulic system.

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 a failing hydraulic pump seal kit is often visible external leakage of hydraulic fluid around the pump shaft. If left unaddressed, this leakage will worsen, leading to a gradual loss of hydraulic system pressure and performance. Continued operation with leaking seals can result in pump damage and potential contamination of the hydraulic fluid.
Ensure the pump shaft and housing are meticulously clean before installation to prevent premature seal wear. Avoid using excessive force or sharp tools when seating the seal, as this can easily damage the sealing lip.
Inspect the hydraulic pump shaft for wear or scoring, and consider replacing the hydraulic fluid and filter if contamination is suspected.
