Multiquip 21364 Fitting Tee 6MJ Bulkhead Run - OEM Replacement Part

This bulkhead run tee fitting provides a critical hydraulic connection point in the blade pitch adjustment system of ride-on trowel machines. The 6MJ configuration ensures proper fluid routing between the trowel arm adjustment mechanism and the pitch control circuit, allowing operators to adjust blade angle during finishing operations.

The blade pitch adjustment system on these machines operates through hydraulic pressure controlled by adjustment bolts on each trowel arm finger. These bolts contact the lower wear plate on the thrust collar to promote consistent blade pitch and finishing quality. Any hydraulic fitting failure in this circuit can result in uneven blade angles, causing the machine to wobble, bounce, or create inconsistent swirls in the concrete surface. When replacing hydraulic fittings, verify that all connections are torque-properly seated and inspect surrounding components for wear, as trowel arm bushings and pitch adjustment bolts work in conjunction with the hydraulic system to maintain precise blade control.
