Normally we try to keep disagreements off the message boards, but, a customer of ours is accusing us of something we did not do and we are looking for some input from others to help us confirm the facts.
A customer sent in his turbo for repair recently and he is claiming we switched turbine housings on him before we sent it back. His original stage 1 wheel exploded in the Turbonetics .63 A/R turbine housing which took large chunks out of the wheel contour surface. Our only option at the time was to open it up to a Stage 2 wheel. Unfortunately, opening to a stage 2 wheel wasn't enough to remove all the damage. The only thing we could do at this point was to create a shim and press it in to the housing then remachine for the stage 2 contour. We charged $50. for all of this work including machining for the stage 2, creating a shim, pressing in the shim and re-machining for the stage 2 contour. He feels he shouldn't have to pay this amount because he doesn't think it's his housing. He provided the picture below where he circled the Turbonetics "T" with a thick grey/red circle before and after it was refurbished. He is claiming the refurbished housing is different and we switched it. I tried to explain to him Turbonetics never offered a turbine housing with just a "T" and there has always been a star behind the logo. It's just not very visible due to the rust and stains on his used housing. I also circled in fine red color two flat spots on the turbine housing ears to show that it is the identical housing. I implored him to call Turbonetics himself to verify that their logo has always had the star behind it, but as far as I know he did not. I also told him that if he searched Turbonetics logo on google he would only find it with the star behind the "T". FTR- I contacted Turbonetics and spoke with the manager who confirmed our findings, but, the customer refuses to do the research himself.
I would appreciate input from anyone familiar with Turbonetics products and their logo.
Thanks!
