Our flywheel was in fairly good shape and it didn’t need to be replaced. We took it to Pfeiffer’s Engine Specialties in Freeport, Illinois, for resurfacing. The bulk of Pfeiffer’s business is performance-engine-oriented (both diesel and gas engines), and the company also has the equipment and experience to resurface flywheels. The technician began the resurfacing procedure by placing our flywheel in a hot tank for cleaning. Here, he rinses the flywheel after cleaning.
