This is a main pump seal kit specifically designed for the primary hydraulic pump on Volvo EC210B excavators, ensuring the containment of high-pressure hydraulic fluid. It is manufactured with durable sealing materials that resist wear and degradation, providing a superior seal compared to compromised original seals that lead to leaks and performance loss. Operators may observe a reduction in hydraulic system performance, external fluid leaks from the main pump housing, or a whining noise emanating from the pump if this seal kit fails.
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 failure is often a slight decrease in hydraulic system responsiveness and potentially a faint whining sound from the main pump. If ignored, this will progress to noticeable power loss during heavy operations and visible hydraulic fluid leaks around the pump shaft. The worst consequence is potential pump damage due to internal leakage and overheating, leading to costly repairs.
Carefully clean the pump housing and shaft, ensuring no dirt or debris is present that could damage the new seals during installation. Ensure all seals are properly seated and oriented according to the kit's instructions to prevent immediate leakage.
Inspect the main hydraulic pump shaft for scoring or wear, and check the hydraulic fluid for contamination before installing the new seal kit.
