S4Q2 Main Bearing & Connecting Rod Bearing STD 32C09-01010 32A19-09010 for Mitsubishi Engine Parts

Product Details

Product Overview

This premium engine bearing set includes both the main bearing and connecting rod bearing, specifically designed for the Mitsubishi S4Q2 diesel engine. The set is manufactured to OEM standard specifications (STD size) and is identified by the part numbers 32C09-01010 and 32A19-09010. As a critical component of the engine’s rotating assembly, these bearings ensure proper crankshaft support and connecting rod alignment, directly impacting engine longevity and performance.

Manufactured by, these bearings are precision-engineered to meet the rigorous demands of heavy-duty applications. While the S4Q2 engine is commonly used in a variety of industrial and construction equipment, this bearing set is a direct replacement for the original parts, providing a reliable solution for engine overhauls and repairs. The set includes all necessary bearings for a complete main and rod bearing replacement on a standard S4Q2 engine block.

FAQ

Q1: How do I confirm these bearings are the correct size for my S4Q2 engine?
These are standard (STD) size bearings. They are designed for a crankshaft and connecting rods that have not been reground. If your engine has been previously rebuilt with undersized bearings (e.g., 0.25mm or 0.50mm), these will not fit. Always check the stamp on the back of your old bearing or measure your crankshaft journal diameter to confirm STD size is required.

Q2: Can I install these bearings without specialized tools?
While basic hand tools are sufficient for removal and installation, we strongly recommend using a plastigage to check oil clearance during assembly. Proper torque specifications for the main bearing caps and connecting rod bolts are critical. If you are not experienced in engine rebuilding, we advise consulting a professional mechanic or referring to the official Mitsubishi S4Q2 service manual.

Q3: What is the recommended maintenance after installing new bearings?
After installation, perform an initial oil change after 50 hours of operation to remove any fine debris from the break-in process. Use high-quality diesel engine oil with the correct viscosity (typically 15W-40 for most climates). Regularly check oil pressure and listen for unusual knocking sounds, which may indicate improper clearance or lubrication issues.
