Multiquip 21763 Worm Counter Shaft Right Side - OEM Replacement Part

The worm counter shaft right side is a critical drive component in ride-on power trowel spider assemblies, transmitting rotational force from the pitch control system to the trowel arms on the right side of the machine. This precision-machined shaft works in conjunction with the pitch adjustment mechanism to control blade angle and ensure smooth, consistent concrete finishing operations.

During maintenance procedures outlined in the official service manual, technicians should inspect the worm counter shaft for wear, damage, or misalignment when disassembling spider assemblies for trowel arm adjustments or blade pitch synchronization on Twin Pitch™ equipped machines. The shaft interfaces directly with the pitch adjustment system, allowing operators to lift the pitch adjustment handle to disengage one side from the Twin Pitch controls for independent blade adjustment. Signs that replacement may be needed include difficulty adjusting pitch on one side, uneven blade engagement, or visible wear on the shaft threads or bearing surfaces.

Compatible with the following Multiquip models:

• JTNS20
• SW20
