Upgrade & Restore Your Wheel Balancer's Performance

The Piezo Assembly, Set Of 3" is a professional-grade mechanical component designed specifically for wheel balancers. Engineered to exact factory tolerances, it replaces original equipment part number 81142663 to maintain balanced, concentric rotation and precise wheel balancing calibration.

Timely replacement of worn components and hardwares is critical to preventing high-speed vibrations, protecting sensitive piezoelectric sensors, and reducing expensive garage downtime.

📋 Factory Service Bulletin Guidance:

Update Date: September 2019
Subject: LEGACY BALANCERS (1 WIRE PIEZOS)

Due to challenges with continued manufacturing of the one wire piezos (pn 8114473), they are scheduled to become obsolete once current inventory is exhausted. These piezos are used in most balancers designed and built prior to the 1250 (i.e. 950, 1050, 1025, 1000, 1000D and others). Should you require piezos to keep these machines functional you can convert them to the current, 2 wire piezos (pn 81142663). You will need to fabricate 3 ground wires, 2 at approximately 18" and 1 at approximately 8", preferably using white 16 gauge wire with a female spade connector on one end and a ring connector on the other (see example below, green wire used for clarity).

Machine Location:

This part is positioned within the rotating shaft, hub adapters, motor assemblies, or safety hood structures of the wheel balancer.
