Horizontal threaded hinge pin kit for BOSS RT3 V-plows

This replacement kit contains one horizontal hinge pin, one flat washer and one hex nut for compatible BOSS RT3 V-plow hinge assemblies. Use MSC09649 as the threaded-kit reference and confirm the required pin against your plow's model, serial number and parts diagram.

The pin has a smooth cylindrical shank, a broad head with flats at one end and a reduced threaded end at the other. The washer and nut retain the threaded end. The supplied parts have a yellow-gold finish.

MSC09649 and MSC04250 identify different retention styles

BOSS identifies MSC09649 as a horizontal threaded hinge pin kit. Its earlier MSC04250 parts listing uses a pin secured with roll pins and cotter pins. When replacing an assembly identified by MSC04250, confirm that the threaded style is suitable for your specific plow before ordering.

Compare the existing pin's shank diameter, working length, head clearance and retaining arrangement with this kit. Check the hinge bore and adjoining parts for wear or damage. A worn hinge may require additional parts beyond a new pin.

Fitting and service checks

Support the plow and follow its service instructions before removing the existing hinge pin. Use the specified pin orientation, hardware arrangement and torque for the confirmed replacement configuration. The nut's shape and finish do not establish its grade or locking specification.

After fitting, check that the pin is retained and the hinge moves as intended through the plow's operating range. Confirm any lubrication requirement from the service information for your assembly.
