Multiquip 61237000 Shaft Seal Kit STH

The Multiquip 61237000 Shaft Seal Kit STH is a genuine OEM component designed for hydrostatic ride-on power trowel models including the STXD6i, HTX44K5, HTX44Y4, HTX44Y5, HTX44K4, and STX55Y6. As an original Multiquip part, 61237000 is manufactured to the same specifications as the factory-installed seal, ensuring a direct, compatible fit in the trowel's drive shaft assembly. Please note this part number has been retired and superseded by Multiquip part — confirm the correct replacement with your parts reference before ordering. DHS Equipment stocks genuine Multiquip OEM parts to keep your finishing equipment running at full capacity.

Key Features

• Genuine OEM Sealing Materials — Manufactured to original Multiquip specification, delivering the correct compression rating and material grade for hydraulic shaft sealing in ride-on trowel applications.
• Direct Shaft Assembly Fit — Engineered to install directly into the trowel's drive shaft housing with correct dimensional tolerancing, matching the original mounting interface without rework.
• Broad HTX and STX Series Coverage — Compatible with STXD6i, HTX44K5, HTX44Y4, HTX44Y5, HTX44K4, and STX55Y6 hydrostatic ride-on power trowels.
• Prevents Hydraulic Fluid Loss — A properly seated shaft seal keeps hydraulic fluid contained within the drive system, maintaining consistent blade pitch control and forward motion response.
• Superseded Part Transparency — Part number 61237000 has been officially retired to 61253000; this listing reflects the original number for cross-reference and procurement accuracy.

The shaft seal kit serves as the primary barrier between the rotating drive shaft and the surrounding hydraulic system in a hydrostatic ride-on power trowel. It prevents hydraulic fluid from escaping around the shaft, which is critical for maintaining operating pressure and precise blade pitch adjustment. When a shaft seal wears or fails, fluid leaks reduce system pressure, causing erratic blade response, loss of drive performance, and potential contamination of surrounding components — making timely replacement essential to consistent finishing results.
