This is a critical seal kit designed to maintain the operational integrity of the main control valve, ensuring precise hydraulic fluid management and preventing internal leakage. Manufactured to meet strict OEM quality standards, it provides reliable sealing and durability superior to worn or damaged seals. Operators may notice erratic hydraulic control, slow response times, or unintended equipment movements when these seals begin to degrade.
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 indication of failing main valve seals is often a slight loss of precision in hydraulic control, such as a 'drift' in boom or bucket position. If ignored, this can progress to more significant internal leakage, leading to slower response times and reduced hydraulic system efficiency. The worst outcome is unpredictable equipment movement or a complete loss of control over specific hydraulic functions, creating an unsafe operating environment.
Carefully clean all internal valve components and ensure seals are properly lubricated with clean hydraulic oil before installation. Avoid using sharp tools that could scratch or damage the delicate sealing surfaces.
Inspect the hydraulic fluid for contamination and clean the hydraulic system filters when replacing main control valve seals.
