Upgrade & Restore Your Wheel Balancer's Performance

The Sonar Module For 3D Balancers is a professional-grade mechanical component designed specifically for wheel balancers. Engineered to exact factory tolerances, it replaces original equipment part number 85000304 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.

๐Ÿ“‹ Factory Service Bulletin Guidance:

Update Date: April 2021
Subject: Balancer Sonar Product Change

Effective 4/22/2021 the new sonar (PN# 85612042) is being used on new 1600 balancers. We will use the remaining inventory of the old sonar (PN# 85000304) on 1500 balancers and for service repairs until that inventory is exhausted (~6-7 months). The bracket is different for the new sonar and the new sonar requires a ground strap added to the PCB. When replacing a sonar in the field please order the direct replacement for the installed sonar. Once inventory nears exhaustion, we will publish the part number for the conversion kit, which will include the sonar, bracket, ground strap, & instructions. โ˜ โ˜ ๏ƒพ โ˜ BASELINE โ˜ โ˜ ๏ƒพ Wheel Balancers (WB) โ˜ โ˜ โ˜ โ˜
