Custom Diesel Machine and Manufacturing
Ryan’s Diesel Service is no stranger when it comes to the manufacturing of high-end diesel products. Ryan believes all products should be manufactured in-house to maintain high levels of quality control.
We currently have a HAAS VF4 5-axis machining center which runs a fair majority of our products. We also have a HAAS TL-1 lathe.
Turbo balancing is all done in-house on either our West Coast Balancer WCB30 or CWT industries balancer.
In addition to diesel turbos being manufactured in-house, we also offer cylinder head machining for diesel and gas engines. In the summer of 2021, Ryan purchased the remaining machines from a closed local machine shop to bring these services in-house. This means all head gasket jobs done by Ryan’s Diesel Service are completed in-house with zero outsourcing. From being washed in our 220f parts washer, to pressure tested and milled they never leave our building. If you are a local customer you can also bring your cylinder heads into the shop for machining and cleaning.
