Dr. Diesel's Tech Tips

Dr. Diesel headshotAs engine professionals, we feel an obligation to share our knowledge with our customers and other engine pros. To do so we publish an ongoing series of “Tech Tips” designed to help you keep your Perkins, Deutz, Deere, or Continental engine up and running, your Hurth marine transmission last longer, your Rockford and Twin Disc® PTO to function better, or your exhaust scrubber and purifier to clean more air.

We share in writing these Tech Tips and try to do one or two a month. These Tech Tips have evolved over the years but they stay constant in their goal of communicating our knowledge to our customers and our fellow engine pros.

Dr. Diesel™ welcomes your comments and suggestions.
