Multiquip 21103 Hydraulic Hose Assembly 0.63" ID x 15" - OEM Replacement Part

This hydraulic hose assembly delivers pressurized fluid between the hydraulic system components on ride-on power trowels, featuring a 0.63-inch inner diameter, 15-inch length, and a 90-degree fitting on one end. Built to R17 specification standards, this hose is critical for maintaining proper hydraulic motor function and ensuring balanced trowel blade speed across both spiders.

On STX-Series ride-on trowels, the two hydraulic drive motors operate independently of each other. When hydraulic hoses deteriorate or fail, you may notice difficult steering control or one spider spinning noticeably faster or slower than the other—clear indicators that hydraulic system components need inspection. Regular monitoring of hydraulic hoses prevents uneven trowel speed and maintains the precision blade control needed for quality concrete finishing work.

The foot pedal controls blade speed by regulating hydraulic flow, making intact, leak-free hoses essential for responsive operation from slow blade speed to maximum RPM. Annual trowel speed checks should include visual inspection of all hydraulic hoses for wear, cracking, or seepage.
