Mitsubishi Manual Features & Content Preview
Working on Mitsubishi L-Series engines requires precise data, not guesswork. This official 147-page Mitsubishi Heavy Industries publication (P/N 99619-15180, first edition April 2001) delivers the exact factory specifications needed for evaluating and maintaining the L2A, L2C, L2E, L3A, L3C, and L3E diesel powerplants. Built primarily for agricultural and industrial applications, these engines demand strict adherence to factory tolerances to operate reliably under heavy loads. Always verify equipment compatibility and completely relieve system pressures before beginning tear-downs to prevent severe injury.
Key references included in this volume:
- Comprehensive structural and maintenance parameters based on the May 1997 base design.
- 96 exploded-view assembly diagrams for precise component identification.
- 18 technical service specification tables for quick bench reference.
Engine System Documentation
This manual breaks down the core systems of the 2001 L-Series engines. Professionals will find detailed component illustrations mapping out the lubrication and fuel systems, alongside the mechanical governor, cooling network, and air intake layout. It provides a deep dive into top-end service, detailing the exact cylinder head and valve train tolerances required for a successful bench rebuild. For instance, cylinder head surface flatness is strict—it must remain within 0.05 mm. Valve seat contact width is equally critical, specified at 1.3 to 1.8 mm.
Technical Specification Highlights
Having the right numbers on hand makes all the difference when micrometering parts. The documentation lists the main journal diameter for the crankshaft at 43 mm, while the crankpin diameter measures exactly 40 mm. When checking clearances, connecting rod oil clearance should sit between 0.022 and 0.052 mm. The cooling system section details a wax-type thermostat with a cracking temperature of 76.5°C ± 1.5°C. For the fuel delivery side, nozzle assembly injection start pressure is definitively set at 140 kgf/cm² (13.7 MPa). This manual serves as the definitive factory baseline for assessing component wear on these industrial diesels.
