Jcb3dx Main Bearing And Connecting Rod Bearing Std 320-09335 320-09471 for Jcb Diesel Engine Parts

Product Details

Product Overview

This set includes both the Main Bearing and Connecting Rod Bearing (Standard Size) specifically designed for the JCB 3DX diesel engine. These critical engine components, identified by OEM reference numbers 320-09335 and 320-09471, are essential for maintaining proper crankshaft and connecting rod clearance, ensuring smooth operation and longevity of your power unit.

As high-wear items, replacing bearings during an engine overhaul or rebuild is a standard procedure. These parts are commonly used in JCB construction and agricultural machinery powered by the 3DX engine platform. Please verify your engine model and existing part numbers to confirm fitment before purchase.

Key Features & Benefits

• Durable Construction: Made from high-quality tri-metal or bi-metal materials to withstand high loads and resist fatigue in demanding working conditions.
• Enhanced Engine Protection: Properly sized bearings prevent metal-to-metal contact, protecting the crankshaft and connecting rods from scoring and damage.
• Complete Set: Includes both main and rod bearings in a single package, simplifying the ordering process for your engine rebuild kit.
• Rigorous Quality Control: Each batch undergoes dimensional inspection and material verification to ensure consistent performance.
• Cost-Effective Solution: A reliable aftermarket alternative to genuine OEM parts, providing excellent value without compromising on quality.

FAQ

1. How do I confirm the correct size for my JCB 3DX engine?

The crankshaft and connecting rods may have been previously ground to an undersize (e.g., 0.25mm, 0.50mm). You must visually inspect the back of the old bearing shells for markings like “STD,” “0.25,” or “0.50.” Alternatively, measure the journal diameter with a micrometer. This listing is for Standard (STD) size only.

2. Can I install these bearings without specialized tools?

While basic hand tools are used, proper installation requires careful cleaning of the bearing saddles, precise torque application using a calibrated torque wrench, and checking the bearing clearance with Plastigauge. We recommend installation by a qualified diesel mechanic to prevent engine damage from incorrect clearance.

3. What is the difference between a Main Bearing and a Connecting Rod Bearing?

Main bearings support the crankshaft within the engine block, while connecting rod bearings fit between the connecting rod and the crankshaft journal. Both are critical for reducing friction and supporting rotational loads. This set includes both types for a complete rebuild of the JCB 3DX engine bottom end.
