About This Manual
This workshop manual provides service and repair procedures for the Perkins 400 Series diesel engines listed below, including those used in JCB equipment. It covers the engine and its associated systems rather than the complete JCB machine.
Step-by-step instructions explain component removal, inspection and refitting, with illustrations to help you follow the procedures. Tightening torques and compression test data provide reference values for workshop checks. The electrical section includes alternator wiring diagrams and diagrams for engines equipped with automatic shutdown.
