This is a main pump seal kit designed to prevent hydraulic fluid leaks from the main hydraulic pump of specific Volvo excavators. It is manufactured using high-quality sealing materials that maintain their integrity under high pressure and temperature, unlike worn seals that become brittle or deformed. Operators may observe external hydraulic fluid leaks around the pump housing, or a gradual loss of hydraulic system pressure and performance 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 most immediate sign of a failing main pump seal kit is visible hydraulic fluid leakage originating from the main pump assembly. If left unaddressed, the leakage will worsen, potentially leading to a significant drop in hydraulic fluid levels and system pressure. A persistent and severe leak can compromise the entire hydraulic system's operation and lead to component damage from low fluid levels or contamination.
Carefully clean the pump housing and shaft surfaces where the seals will be installed to ensure a proper seal. Avoid using sharp tools that could nick or scratch the seal lips during installation.
When replacing the main pump seal kit, it is recommended to inspect the hydraulic fluid for contamination and check the condition of the pump shaft.
