This main pump seal kit is essential for maintaining the integrity of the primary hydraulic pump, preventing internal and external leaks of hydraulic fluid. It comprises various seals and O-rings designed to withstand high pressures and temperatures within the hydraulic system. A leaking seal kit can lead to a gradual loss of hydraulic pressure, sluggish operation, and visible fluid leaks around the pump housing.
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.
Initial signs of a failing seal kit include a slight decrease in hydraulic system pressure or responsiveness, and potentially small external fluid drips from the pump. If ignored, the leaks will worsen, leading to significant hydraulic fluid loss, reduced pump efficiency, and potential cavitation damage. Continued operation risks complete hydraulic system failure, immobilizing the equipment.
Thoroughly clean all sealing surfaces on the pump housing and shaft before installing new seals to ensure a proper seal. Avoid using sharp tools that could nick or damage the delicate sealing lips of the O-rings and seals.
Inspect the hydraulic pump shaft for scoring or wear, and clean the hydraulic reservoir and strainers for debris when replacing the seal kit.
