This is a seal kit specifically designed for the main hydraulic pump on Volvo EC220D excavators, preventing internal and external fluid leaks. It is manufactured to precise dimensions and material specifications, ensuring a reliable seal unlike a worn or damaged kit. Operators may experience a noticeable drop in hydraulic pressure, sluggish operation, or visible fluid leaks around the pump housing when this kit fails.

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.
Visible hydraulic fluid leaks originating from the main pump housing are a primary indicator of seal failure. If ignored, these leaks will worsen, leading to a significant loss of hydraulic system pressure and performance. Continued operation with a leaking pump can cause internal damage and costly repairs.
Carefully inspect the pump shaft and housing for any burrs or damage that could compromise the new seals before installation. Ensure all seals are properly seated and lubricated with clean hydraulic fluid to prevent tearing during assembly.
Inspect the hydraulic fluid and filter for signs of seal material degradation and consider replacing the hydraulic filter.
