Daido C240 Connecting Rod Bearing R4536 Std | Isuzu Excavator Engine Parts

Product Details

Product Overview

This premium Daido connecting rod bearing, part number R4536, is a standard-size (Std) component specifically designed for the Isuzu C240 diesel engine. As a genuine new part sourced from Japan, it serves as a critical internal engine component for maintaining precise crankshaft clearances and oil film control.

Commonly used in Isuzu Medium Duty equipment, this bearing is particularly suited for excavator applications where high load tolerance and durability are required. While the C240 engine is a well-known industrial power unit, we recommend verifying your specific engine block and crankshaft journal dimensions to confirm fitment for your exact equipment model and year.

Key Features & Benefits

• Genuine Daido Quality: Manufactured to original equipment specifications for reliable performance and long service life.
• Precision Standard Size: Factory Std sizing ensures correct oil clearance when installed in a properly measured and machined C240 engine block.
• High Wear Resistance: Engineered with a specialized tri-metal layer structure to withstand the high compression and load cycles of excavator operation.
• Corrosion Protection: Advanced overlay plating resists chemical degradation from engine oil and combustion byproducts.
• Fatigue Strength: Designed to handle the stress of continuous heavy-duty cycles in earthmoving and construction machinery.
• Direct Replacement: Exact match for the R4536 part number, simplifying parts ordering and inventory management.

FAQ

Q1: Is this bearing a direct fit for my Isuzu C240 engine?
This is the standard-size Daido bearing for the C240 connecting rod journal. However, engine wear over time may require an oversized bearing (0.25mm, 0.50mm, etc.). You must measure your crankshaft journal diameter and connecting rod bore to confirm that “Std” is correct for your application.

Q2: What is the correct installation procedure for this bearing?
Installation requires precision. Clean the connecting rod and cap mating surfaces thoroughly. Apply clean engine oil to the bearing surface. Torque the connecting rod bolts to the factory specification for the C240 engine (typically 53-58 Nm for the rod bolts, plus a final angle turn as per service manual). Always use new bolts and check rod side clearance after installation.

Q3: Can I use this bearing with a reground crankshaft?
No. This is a Standard size bearing. If your crankshaft has been reground (undersized), you must use an oversized bearing (e.g., 0.25mm or 0.50mm undersized) to match the reduced journal diameter. Using a Std bearing on a reground journal will result in excessive oil clearance and catastrophic engine failure.
