Multiquip 21336 Hose Assembly 3/8 x 22 TR Ends - OEM Replacement Part

This hydraulic hose assembly delivers pressurized fluid to the trowel arm system on ride-on power trowels, enabling precise blade pitch control during concrete finishing operations. The 3/8-inch diameter hose features threaded (TR) end fittings on both sides for secure connection to the hydraulic system that adjusts blade angle during operation.

The blade pitch adjustment system controlled by this hose assembly is critical for achieving proper concrete finish quality. When adjusting blade pitch using the adjustment bolt on the trowel arm, technicians should reference the Trowel Arm Adjustment Fixture (P.N. 9177) for consistent results. Properly functioning hydraulic hoses ensure responsive blade angle changes, preventing common issues like uneven swirls, concrete bouncing, or rolling during finishing operations.

Failed or leaking hydraulic hoses can result in loss of blade pitch control, leading to inconsistent concrete finishing and potential machine wobble. Regular inspection of hydraulic lines during routine maintenance helps prevent unexpected downtime during critical finishing work.
