Description

When your excavator’s upper house starts rotating rough or you notice hydraulic fluid pooling around the slew motor, worn seals are usually the culprit. The slew motor is what lets your excavator spin 360 degrees smoothly, and when those seals fail, you lose hydraulic pressure and risk expensive internal damage. This complete seal kit gets your Hitachi EX100WD turning like new again.

What You’re Getting

Complete seal set designed specifically for Hitachi slew motor service
High-pressure seals that handle the heat and stress of continuous rotation
Materials engineered to resist hydraulic fluid breakdown and temperature extremes
All seals needed for a complete rebuild – no guessing what else you might need

Built for Real Excavator Work

Your Hitachi EX100WD is built for versatility – whether you’re digging ditches, loading trucks, or doing utility work where you need to rotate constantly. The slew motor takes a beating with all that turning under load, especially when you’re working in tight spaces or swinging heavy buckets. This seal kit is designed for the demanding hydraulic pressures and continuous operation that wheeled excavators face in real-world conditions.

Made to Last

Slew motors operate under some of the highest pressures in your excavator’s hydraulic system. These seals are manufactured from premium compounds that resist the heat generated by continuous rotation and maintain flexibility even after thousands of operating hours. They’re built to handle the pressure spikes that come with sudden direction changes and heavy loads.

Installation Notes

Slew motor rebuilding requires patience and cleanliness – any contamination will destroy new seals quickly. Clean all components thoroughly and inspect the motor housing for scoring that could damage seals. Use proper hydraulic fluid for lubrication during assembly, and cycle the motor slowly after installation to properly seat all seals.
