Mitsubishi 4G61, 4G63, 4G64 manual: 1992 edition

In-Depth Engine Reference for Mitsubishi 4G6 Series

If you want a single, comprehensive engine documentation that brings together detailed mechanical specifications and component groupings for the Mitsubishi 4G61, 4G63, and 4G64 engines from 1992, this manual delivers exactly that.

This service manual has been organized to mirror the factory’s structure for engine repair and reference. Instead of a flat list of chapter titles, the narrative below maps related systems into logical groupings so you can easily see how major engine components and sub-assemblies are documented.

Core Engine Mechanical Assemblies

The manual begins with the heart of the vehicle: the engine block and associated mechanical groupings. Sections cover crankshaft, flywheel, and drive plate layouts along with piston, connecting rod, and oil pump arrangements. This section gives you a clear picture of how Mitsubishi documents the internal architecture of these engines.

Cylinder Head, Valves and Camshaft Systems

Next, the documentation groups cylinder head and valve assemblies, including separate coverage for SOHC and DOHC configurations. Rocker arms, camshafts, and timing belt systems are referenced in a way that highlights how these elements interact within the valve train and overall engine operation.

Intake, Exhaust and Turbocharger Networks

Fuel delivery and air handling sections describe intake manifold layouts, throttle body references, and fuel/emission control systems. Exhaust manifolds and turbocharger components are also grouped here, showing how forced induction and exhaust routing are integrated into the engine architecture.

Ignition, Charging and Electrical Interfaces

The manual includes sections focused on electrical system components related to engine function, such as generator and ignition systems for both SOHC and DOHC configurations. These groupings provide insight into how power distribution and timing are documented within the broader engine network.

General Specifications and Service References

Detailed service specifications, torque values, sealant guidelines, and other key reference tables are presented in dedicated sections. These technical data groupings give you exact numerical baselines that tie into the mechanical and electrical layouts.
