Product Details
Product Overview
This premium engine bearing set is specifically engineered for the Kubota V4300 diesel engine, a critical power unit commonly found in industrial machinery, agricultural tractors, and construction equipment. As a direct replacement for OEM part numbers 15451-23930 (Main Bearing) and 16541-22313 (Connecting Rod Bearing), this set ensures precise fitment and reliable performance. We are a global supplier with extensive export experience to North America, Europe, Asia-Pacific, the Middle East, and South America, offering fast shipping to major ports and industrial hubs worldwide.
Key Features & Benefits
Precision Engineering: Manufactured to strict OEM tolerances for a perfect fit without modification, reducing installation time.
High Load Capacity: Designed to withstand the high compression and torque demands of the Kubota V4300 engine, ensuring long service life.
Superior Wear Resistance: Utilizes a high-quality tri-metal or bi-metal construction (depending on variant) to minimize friction and resist scoring under heavy loads.
Oil Retention: Optimized oil grooves and surface finish ensure proper lubrication, reducing the risk of bearing seizure and extending engine life.
Standard (Std) Size: This set is for engines with standard crankshaft journals. It eliminates guesswork for standard rebuilds.

FAQ
Q: How do I confirm this bearing set is correct for my V4300 engine? A: Please check the stamping on your engine block. It should clearly state “V4300”. For absolute certainty, remove one main bearing cap and one rod cap, and measure the journal diameter with a micrometer. If the crankshaft is standard size (un-ground), this “Std” set is the correct choice.
Q: Do I need to replace the main bearings and rod bearings at the same time? A: Yes, it is a best practice. While you might replace only one set, the other set has likely experienced similar wear. Replacing both simultaneously ensures uniform oil clearance and load distribution, maximizing the rebuild’s lifespan. This set is designed for a full replacement.
Q: What is the recommended installation procedure for these bearings? A: Always clean the bearing bore and the back of the new bearing shell thoroughly. Apply a thin layer of clean engine oil to the bearing surface. Torque the main and rod cap bolts to the factory specifications for the V4300 engine (typically requiring a torque wrench). After installation, verify the crankshaft rotates freely by hand. We recommend consulting the Kubota V4300 service manual for the exact torque values and sequence.
