Multiquip 61253000 Complete Seal Kit Front & Back End

The Multiquip 61253000 Complete Seal Kit Front & Back End is a genuine OEM seal kit designed for STX55J6, STX55Y6, and STXD6i hydrostatic ride-on power trowels. Sourced directly from Multiquip, this kit delivers the exact seal materials, compression ratings, and dimensional tolerances specified for the STX series hydraulic system. It covers both the front and back end of the assembly, giving you everything needed for a complete service in a single part number. Confirm your model code against the fitment list before ordering to ensure a direct, no-hassle installation.

Key Features

• Full-Coverage OEM Seal Set — Includes seals for both the front and back end of the assembly, eliminating the need to source individual components separately.
• Hydraulic System Integrity — Engineered to maintain proper fluid containment within the STX series hydrostatic drive, preventing pressure loss that can cause sluggish blade response or loss of drive control.
• Exact OEM Material Specification — Genuine Multiquip seals are produced to the same durometer and chemical-resistance ratings as the originals, standing up to hydraulic fluid exposure and heat cycling.
• Confirmed Fitment for STX Series — Verified for STX55J6, STX55Y6, and STXD6i hydrostatic ride-on trowels; check your model code before ordering.
• Supports Preventive Maintenance — Replacing seals at service intervals before leaks develop protects downstream hydraulic components from contamination and wear.

Hydraulic seals in a ride-on trowel's hydrostatic drive system contain pressurized fluid that powers both blade pitch adjustment and machine propulsion. When front or back end seals degrade, hydraulic fluid can leak past the seal faces, causing a drop in system pressure that leads to inconsistent blade pitch control, reduced ground speed, or complete loss of drive function on the trowel. Replacing the full seal kit — both front and back end — restores proper pressure containment, ensures consistent hydraulic response across all operating conditions, and prevents fluid loss from contaminating the surrounding drivetrain components.
