Multiquip 21400 Hydraulic Tank Hand Wheel Plug - OEM Replacement Part

The hydraulic tank hand wheel plug is a critical sealing component for the hydraulic reservoir system on Multiquip ride-on power trowels. This plug maintains proper hydraulic fluid containment while providing accessible service access through the hand wheel design, allowing technicians to check fluid levels and perform hydraulic system maintenance without tools. The hand wheel feature enables quick removal during routine service intervals or when diagnosing hydraulic performance issues such as sluggish steering response or reduced rotor blade pitch control.

Designed specifically for ride-on power trowel hydraulic systems, this OEM plug ensures proper sealing pressure and thread engagement to prevent hydraulic fluid leaks that can lead to system contamination, reduced performance, or costly hydraulic component damage. Regular inspection of this plug during pre-operation checks helps identify wear or cross-threading before they compromise hydraulic system integrity.

Compatible with the following Multiquip ride-on power trowel models:

• HTX-44K4
• HTXD6i
• STX55J6
