New ZBAG DynoIn December, ZBAG purchased a new manual transmission dynometer, or dyno, that has an updated high-frequency drive, a larger frame, and a 40-horsepower motor to replace the outdated diode-operated drive and 30-horsepower motor on the old dyno. This important piece of equipment enhances ZBAG’s ability to send out rebuilt transmissions that are functioning at optimum levels.

The dyno is an important component of ZBAG’s quality control program, according to equipment purchaser Bill Babcock. It enables ZBAG to keep their warranty return ratio at an industry low, providing value and reliability to each customer who buys a rebuilt transmission.

“Every transmission is tested,” John Ramboldt, dyno operator, reported.  Each unit goes from the builder’s bench to the dyno, then to shipping or to the shelf. It takes about 45 minutes to fill each unit with transmission fluid, test it, and then drain the unit. On the dyno, each transmission is checked for gear noise, leaks, complete gear engagement on shifting, and ease of shifting.  The procedure ensures all rebuilt transmissions are in top performance condition. If any problems are found, the transmission is returned to the builder’s bench, corrected, and then sent back to the dyno for another complete round of testing.

The new dyno was purchased from Superflow in Des Moines, IA, and the process of getting it delivered took longer than anticipated because of unexpected machining delays.

Now that the new dyno is in place and operational, the original dyno will be retrofitted to evaluate transfer case performance, according to Bill. This is another way ZBAG is working to ensure the customers who purchase the rebuilt transfer cases experience the same quality and reliability as the customers who purchase ZBAG’s rebuilt transmissions.
