Product Introduction: Crankshaft 504680 for Caterpillar D6E Dozers
Overview
The Crankshaft 504680 is a precision-engineered replacement part designed for Caterpillar D6E dozers, specifically used to convert the linear motion of pistons into rotational motion, driving the engine’s output. This new crankshaft is critical for restoring engine performance in heavy-duty applications such as earthmoving and construction. Available as a new aftermarket or genuine OEM part, it provides a reliable and cost-effective solution for engine repair or overhaul.
Key Features
- Material: Constructed from high-grade forged steel or cast iron, designed to withstand high torsional forces, resist wear, and perform reliably in demanding conditions. Features precision-machined main and connecting rod journals for optimal bearing fitment and durability.
- Design: Precision-machined to OEM specifications, featuring five main journals and four connecting rod journals, balanced for smooth operation. Includes counterweights to reduce vibration and is compatible with standard or undersize bearings for regrinding applications. May include main bearings, connecting rod bearings, and thrust washers in some kits.
- Compatibility: Designed for the Caterpillar D6E dozer, powered by the Caterpillar 3306 engine, a 6-cylinder, 10.5-liter diesel engine. Used in:
- Dozers: Caterpillar D6E, D6E SR (Serial Numbers: 2MJ00001-UP, 8FJ00001-UP, and others). May also fit related models (e.g., D6D, D6C) with the 3306 engine, but exact compatibility must be verified using the engine’s serial number via CAT SIS, as compatibility cannot be confirmed without it per Caterpillar’s policy.
- Dimensions: Specific dimensions are not publicly detailed but conform to OEM standards for the 3306 engine, with a bore of 4.75 in (120.7 mm) and stroke of 6.0 in (152.4 mm). Approximate crankshaft length is 40-50 in (101-127 cm).
- Quality Assurance: New crankshafts meet OEM standards with magnaflux testing to detect cracks, manufactured in ISO 9001-certified facilities.
Benefits
- Enhanced Durability: Forged steel or cast iron construction ensures high strength and resistance to fatigue, extending service life in rugged dozing applications.
- Reliable Performance: Precision balancing and machining ensure smooth power delivery, producing approximately 140-160 hp for the D6E’s 3306 engine, optimizing machine performance.
- Cost-Effective: New aftermarket options reduce costs by 20-40% compared to OEM crankshafts; no core charge simplifies procurement.
- Ease of Installation: Direct-fit design, often supplied with bearings, streamlines installation, minimizing downtime during engine rebuilds.
