INSPECTION

CRANKSHAFT OIL CLEARANCE (PLASTIGAUGE METHOD)

NOTE

If the oil clearance exceeds the limit, replace the bearing, and crankshaft if necessary.

This crankshaft oil clearance can be measured easily by using a plastic gauge, as follows:

1Remove oil and grease and any other foreign material from crankshaft journal and bearing inner surface.

2Install the crankshaft.

3Cut the plastigauge to the same length as the width of bearing and place it on journal in parallel with its axis.

4Gently place the crankshaft bearing cap over it and tighten the bolts to the specified torque.

5Remove the bolts and gently remove the crankshaft bearing cap.

6Measure the width of the crushed plastic gauge at its widest section by using a scale printed on the plastigauge package.

Standard values: 0.02 - 0.04 mm

Limit: 0.1 mm

CYLINDER BLOCK

(1)Visually check for scratches, rust and corrosion. Also use flaw detecting agents and the like to check for cracks. If there are any defects, rectify the cylinder block.

(2)Measure the flatness of the cylinder block top surface with a straight edge and a thickness gauge. During measurement, the cylinder block top surface must be free from gasket pieces and the like.

Standard values: 0.05 mm

Limit: 0.1 mm

(3)Check for scratches or seizure of the cylinder wall. If there are any defects, correct (bore it a oversize) or change the cylinder block.

(4)Measure the inside diameter and the ovality of the cylinder. If the cylinder is overly worn, correct it to a larger size and change the pistons and the piston rings.

Standard value:

Cylinder inside diameter 91.1 mm Ovality: 0.01 mm

6G7 specifications

The Mitsubishi 6G7 engine is a robust V6 gasoline engine that has garnered attention for its blend of performance and efficiency. Primarily designed for use in a variety of Mitsubishi vehicles, including sedans and SUVs, the 6G7 series illustrates the engineering prowess of Mitsubishi in creating reliable and powerful engines.

One of the standout features of the 6G7 engine is its V6 configuration, which provides a good balance of power and smoothness. This engine typically displaces 3.0 liters, though variants exist with slightly different displacements. The 6G7 showcases a double overhead camshaft (DOHC) design, which facilitates efficient airflow and enhances power output. This configuration allows the engine to produce a substantial amount of horsepower while maintaining fuel efficiency, making it an attractive option for both performance-driven drivers and those focused on daily commuting.

In terms of technology, the 6G7 utilizes Mitsubishi’s advanced fuel injection system, which optimizes the fuel-air mixture for efficient combustion. This not only contributes to improved power output but also helps in reducing emissions, making the engine more environmentally friendly. Additionally, the integration of a variable valve timing (VVT) system enhances the engine's performance across various RPM ranges, providing both low-end torque and high-end power.

The 6G7 is designed with durability in mind. It features a robust iron block and aluminum alloy cylinder heads, which contribute to the engine's longevity and overall reliability. The use of advanced materials and manufacturing techniques helps to minimize wear and extend the lifespan of critical components.

Another important characteristic of the 6G7 engine is its smooth operation. The V6 configuration inherently provides balance, reducing vibrations and ensuring a refined driving experience. Coupled with a well-tuned exhaust system, the engine produces a pleasing sound that enhances the overall driving experience without being overwhelming.

In conclusion, the Mitsubishi 6G7 engine series stands out for its combination of power, efficiency, and durability. With advanced technologies like DOHC, VVT, and an efficient fuel injection system, the 6G7 remains a popular choice in various Mitsubishi models. Its smooth operation and robust construction further establish it as a reliable engine, appealing to a wide range of drivers seeking performance without sacrificing efficiency. The 6G7 serves as a testament to Mitsubishi's commitment to engineering excellence and innovation in the automotive industry.
