Horner received a call from a diesel engine company regarding a chassis dyno that had failed. If you do not know, a chassis dyno is a test cell in which a vehicle is driven into and the tires ride on a roll to simulate driving. This particular test cell is a four wheel drive test cell and the customer is measuring emissions of the vehicle. The customer was experiencing issues with the rear assembly. Horner was on-site several times helping the customer identify the problem and determined it would be best for the unit to be pulled and the motor sent to the shop. With this information, the customer reached out to the OEM and was told it would be a 26 week turnaround time and the customer did not have that much time to be down. While on-site we discussed only wanting the motor and not the entire assembly. To John Brown’s surprise we received the entire dyno assembly! Upon its arrival, Joe Oliver tested the motor and determined the motor had two windings and one of the windings had failed. After several conference calls between the customer, Mike Butler and Billy Burge, it was determined that we would only commit to working on this unit if we had factory support from the OEM. The OEM is located in Czech Republic and sure enough we had two factory mechanics on-site and one application engineer from the US office in Detroit. Matt Hoke and several others in the motor shop worked with the OEM to get the unit carefully dismantled. While the Indianapolis motor shop rewound the motor, purchasing had to locate several sets of replacement bearings along with other miscellaneous parts and pieces. The shop took less time to rewind the motor than expected and parts were expedited. Before the assembly process could start, the motor had to be tested in 100 RPM increments for 1 hour, while being hung from the overhead crane…thank you to Kevin Bimrose and Joe Oliver for getting the VFD to operate correctly! After several hours of testing, the motor passed all vibration and temperature requirements and the greenlight was given to proceed with assembly. The guys in the motor shop worked with the OEM to get everything assembled and loaded on to the truck to be delivered.
