Multiquip 9900374000 Complete Seal Kit (Shaft & Back End) - OEM Replacement Part

This complete seal kit restores critical sealing integrity in Multiquip ride-on trowel gearboxes by replacing both shaft and back end seals that prevent hydraulic fluid and gear oil contamination. Essential for maintaining optimal hydraulic system performance and preventing costly fluid leaks that can lead to premature component failure in high-hour trowel operations.

The kit includes all necessary shaft seals and back end seals engineered to OEM specifications for proper fitment and reliable sealing under the demanding conditions of concrete finishing work. Regular seal inspection and replacement prevents moisture ingress, maintains proper lubrication levels, and extends the service life of expensive gearbox components. Recommended during major service intervals or whenever fluid leakage is observed around shaft housings or back end assemblies.

Compatible with the following Multiquip ride-on trowel models:

• HTX-44K4
• STX55J6
