Mitsubishi Canter 4m42 Service Manual [repack] Jun 2026
Based on the analysis of the Mitsubishi Canter 4M42 service manual, we recommend the following:
Using correct torque values is mandatory to prevent fluid leaks, stripped threads, or catastrophic structural warping. Below are the standard factory torque values commonly found in the 4M42 workshop manual: Torque Specification (Nm / lb-ft) Notes / Sequence Multi-stage angle tightening Refer to manual for exact angle rotation sequence Main Bearing Cap Bolts 49 Nm + 90° turn Always use new bolts during a complete rebuild Connecting Rod Cap Nuts 29 Nm + 90° turn Lubricate threads with clean engine oil before installation Flywheel Bolts 185 Nm (136 lb-ft) Tighten in a cross-star pattern Crankshaft Pulley Bolt 265 Nm (195 lb-ft) Requires a counter-holding tool to prevent rotation Fuel Injector Retainer Bolts 25 Nm (18 lb-ft) Over-tightening can deform the injector body Common Troubleshooting Scenarios
The manual directs you to check fuel low-pressure delivery first. If the fuel filter is clear and priming pump pressure is present, you must use a scanner to check "Fuel Rail Pressure During Cranking." If the pressure does not reach the minimum threshold (typically around 20-25 MPa), the manual points to a faulty suction control valve (SCV) on the supply pump or a leaking injector pressure-relief valve.
