Air Cooled Engines 101

Course Description

A “from the ground up” approach to residential single- and two-cylinder air cooled engines commonly used in home standby generators. This class will be a great introduction for rookie techs who have little to no engine experience at all, all the way up to seasoned techs looking for a refresher.

In this class, we will discuss breaking down parts used in the engine one at a time, common failure points found in the Kohler, Generac, Cummins, and Briggs & Stratton engines, and discuss some diagnostic procedures. Once classroom discussions are complete, each student will tear down a complete engine and reassemble it on a bench. We will end class with live troubleshooting on intentionally bugged machines that simulate real custom complaints you’d come across in the field as a tech.

Course Instructor & Director of Education, On Site Power Academy

Jamie Claudeo Jr. started turning wrenches under his fathers watchful eye when he was just 10 years old climbing in and out of large commercial boilers.  By end of high school he was attending vocational school for electrical trades and before graduating succeeded in taking first place at the state level SkillsUSA competition.  Having a love for engines and machinery, he eventually moved into working on large trucks for Peterbilt after attending Universal Technical Institute in Pennsylvania and Arizona.  After Hurricane Sandy decimated the northeast in 2012 he eventually made his way into Power generation, working for a small company out of NJ.  His strong understanding of both electrical and engines allowed him to move up quickly – taking on large projects, and hard to troubleshoot problems across several states until eventually choosing to start his own business in 2022.

During his free time, Jamie enjoys traveling the world, dark beer, hiking, rock climbing, running and tinkering with old machinery.  On more quiet relaxed evenings you can find him curled up on a giant bean bag chair enjoying a good video game.
