6D14 Rocker Arm Shaft ME072020 Small Hole – Mitsubishi Engine Parts for Excavator & Industrial Use

Product Details

Product Overview

This high-quality rocker arm shaft, identified by part number ME072020, is specifically designed for the Mitsubishi 6D14 diesel engine. As a critical component within the valve train system, this shaft ensures precise rocker arm movement, maintaining optimal valve timing and engine performance. The “Small Hole” variant refers to specific oil passage dimensions, crucial for proper lubrication of the rocker arm assembly.

Manufactured by, this component is engineered to meet OEM size specifications, making it a reliable replacement for maintenance or overhaul of Mitsubishi 6D14 engines. Commonly used in heavy-duty applications such as construction machinery (excavators, bulldozers), industrial equipment, agricultural tractors, generator sets, marine propulsion, and material handling vehicles, this rocker arm shaft is a vital part for restoring engine efficiency and longevity.

Please verify your engine model and existing part configuration before purchase to ensure compatibility. This product is a direct replacement part, not a modified or performance upgrade.

FAQ

Q: How do I confirm this rocker arm shaft fits my Mitsubishi 6D14 engine?
A: First, locate the part number on your existing rocker arm shaft (look for ME072020 or similar). Measure the shaft diameter and length, and verify it matches OEM specifications. If your engine is a 6D14 with a “small hole” oil passage design, this part is likely compatible. We recommend consulting your engine service manual or contacting our technical support with your engine serial number for confirmation.

Q: What is the difference between the “Small Hole” and “Large Hole” versions?
A: The “Small Hole” variant has a reduced internal oil passage diameter compared to the standard version. This is specific to certain 6D14 engine builds that require lower oil flow to the rocker arms to maintain correct lubrication pressure. Using the wrong version can cause oil starvation or excessive leakage. Always match the hole size to your original part.

Q: What maintenance is recommended after installing a new rocker arm shaft?
A: After installation, check and adjust valve clearances according to the Mitsubishi 6D14 service manual (typically 0.25mm intake / 0.35mm exhaust). Run the engine at idle for 5-10 minutes to ensure proper oil circulation to the rocker arms. Inspect for any unusual noise or oil leaks. Retorque the rocker arm shaft bolts after the first 50 hours of operation.
