One year ago, Onsite Diesel was officially acquired by Deutz Corporation, uniting our local service team with a global leader in engine manufacturing.

365 days later, this acquisition continues to bring great results. Becoming part of Deutz has expanded our service footprint, boosted our technical capabilities, and allowed us to deliver even greater value to our customers every day.

Thank you to our customers, industry partners, and community for your continued support through this milestone year. We look forward to building on this strong foundation in Year Two and beyond!

One of the most important processes of the job that makes all the difference is proper cleaning and surface prep before A rebuild. You can’t spot cracks, thread damage, or wear under a layer of sludge. Cleaning every bolt and gear is step one in quality control.
