I rebuilt my own turbo and called for pricing to rebalance my cartridge before I reinstall it. The woman who answer the phone at first explained that they do not balance cartridges that they do not put together themselves because ‘if they do so and it blows up then I might blame them’. The machine that balances the compressor wheels will not allow that to happen because it will stop and tell you where to grind off metal before it increases the speed to higher RPMs. She then argued that if it seizes-​up then I would complain – lol, it isn’t my first time around a turbo; additionally, there isn’t too many parts to these things as well. It feels like these guys just try to are just trying to build-​up the fees – there are companies that you can mail your cartridge into for balancing…

Not a reputable Business, they will not honor their warranty. The manager comes across as if she knows everything and she likes to belittle people.
Looking past the manager, the owner of the company rates about the same or worse !

Had an old John Deere pump rebuilt by these folks. Good price and great customer service. The lady there took the time to show me how to properly install the driveshaft in the pump. She was very informative and saved me a world of trouble. You can’t find customer service like that these days.

I wanted to bang my head against the wall. The lady that works there sells me the wrong part for my diesel truck because despite being an official distributor they didn’t have access to the part I needed saying it was on national back order and no one will have the correct part. She was certain that the substitute part she was selling me would work. When the part didn’t work — I was able to find the part online and when I went to return the item to diamond diesel the lady was extremely combative. So unless you want to watch a grown lady have a tantrum like a child — throwing papers around while she barks about how much more she knows then you or anyone else DONT GO HERE.

So my old diesel mercedes has not been running like it should. I suspected a bad injector or two and after calling around i was directed to this place. What a gem hidden in west sacramento. they tested my injectors while I was there and found two of them to be «pissing» so they are rebuilding them for me at a fraction of the 250+ for new ones. from what i can see they do great work on all diesels, including turbos injection pumps etc. (unfortunatly my car is non turbo).
