FAQ

Q1: How do I confirm this part (5i7528) fits my Mitsubishi S6K engine?

A: The best way to confirm fitment is to visually compare your old part with the images provided or check the part number stamped on the original component. The 5i7528 is a standard OEM number for the eccentric bush in S6K and S4S engines. If your engine serial number matches these models, it is highly likely compatible.

Q2: What is the function of the eccentric bearing bush, and what happens if it fails?

A: This bushing controls the eccentric movement of a shaft (often for the fuel injection pump). If it wears out, you may experience erratic engine timing, loss of power, hard starting, or unusual knocking noises from the engine. Replacing it promptly is crucial to prevent damage to the shaft and surrounding components.

Q3: What is the recommended installation procedure for this bushing?

A: Installation should be performed by a qualified diesel mechanic. The bushing must be pressed into the housing using a proper press tool to avoid distortion. After installation, ensure the inner diameter is within spec and lubricate the bushing with clean engine oil before assembly. Never hammer the bushing into place.
