Multiquip 21110 Hose Assembly .38 ID x 45.5" - OEM Replacement Part for Trowels

This hydraulic hose assembly delivers pressurized fluid to the trowel arm pitch adjustment system on ride-on power trowels, enabling operators to control blade angle for optimal concrete finishing. The 0.38-inch inner diameter and 45.5-inch length are precisely engineered to maintain proper hydraulic flow and pressure during blade pitch adjustments.

The blade pitch adjustment system is critical for achieving consistent concrete finishes. As noted in Multiquip service procedures, adjustments are made by tightening or loosening the blade pitch adjustment bolt, which relies on proper hydraulic pressure delivered through this hose assembly. Failed or deteriorating hydraulic hoses can result in inconsistent blade angles, causing the machine to wobble, bounce, or create uneven swirls in concrete—symptoms that also indicate potential trowel arm bushing or spider assembly issues.

When servicing the pitch control system, technicians should verify that all blades maintain the same pitch angle as measured at the spider. Blade bolts should be torqued to 9 ft-lbs during reinstallation. Replace this hose assembly if you observe fluid leaks, reduced pitch control response, or visible deterioration of the outer covering.
