K4F K4D STD Connecting Rod Bearing for Mitsubishi Engine Repair Parts

Product Details

Product Overview

This high-precision connecting rod bearing is specifically designed for the Mitsubishi K4F and K4D diesel engine series. Manufactured to Standard (STD) OEM size specifications, this bearing is an essential component for engine overhaul and repair projects. As a critical part of the engine’s rotating assembly, this bearing ensures a precise fit between the connecting rod and the crankshaft journal, reducing friction and supporting the high loads generated during diesel combustion.

Ideal for use in construction machinery, agricultural equipment, industrial generators, and marine applications, this K4F/K4D connecting rod bearing is a direct replacement for worn or damaged components. It is commonly used in engines powering equipment like mini excavators, forklifts, and small gensets, where reliable engine performance is paramount. Please verify your engine model and bearing size before purchase to ensure correct fitment.

Key Features & Benefits

FAQ

Q1: How can I confirm this bearing fits my Mitsubishi K4F engine?
A: First, confirm your engine model is either K4F or K4D. Second, check your current bearing for any markings indicating size. This listing is for “STD” (Standard) size. If your crankshaft has been reground, you will require an undersized bearing (e.g., 0.25mm or 0.50mm). We recommend cross-referencing your old bearing part number or consulting your engine manual.

Q2: What is the recommended installation procedure for these bearings?
A: Installation should be performed by a qualified mechanic. Ensure the bearing housing and crankshaft journal are perfectly clean and free of debris. Apply clean engine oil to the bearing surface before installation. Tighten the connecting rod bolts to the manufacturer’s specified torque settings using a calibrated torque wrench. Always replace bolts if specified by the engine manufacturer.

Q3: Do you provide an OEM service for custom branding or packaging?
A: Yes, OEM service is available. We can provide custom packaging with your brand logo and part numbers for bulk orders. Please contact our B2B sales team with your requirements for a quotation. Minimum order quantities may apply.
