7C2991 EJECTOR AS CATERPILLAR – Engineered for Reliable Discharge Efficiency

In the heart of heavy machinery productivity lies a crucial component that often goes unseen but plays a significant role in material handling and operational speed: the ejector assembly. The 7C2991 EJECTOR AS CATERPILLAR is a high-strength, precision-crafted cylindrical ejector engineered to optimize the unloading mechanism of specific Caterpillar machines. Whether in the mining pits, construction zones, or quarries, this component contributes directly to operational output by enhancing material ejection and preventing downtime due to clogging or incomplete dumping.

Product Overview

The 7C2991 EJECTOR AS CATERPILLAR is a large tubular steel part with structural reinforcements and expertly welded seams, designed to endure the high pressures and repeated impact stresses that come from discharging dense loads such as earth, gravel, or debris. Its geometry ensures smooth and even material push across the dump body, preventing uneven wear and maximizing container clearing efficiency.

Key Technical Specifications:

• Product Name: 7C2991 Ejector Assembly

• Part Category: Hydraulic Dump System Component

• Primary Use: Material discharge/ejection

• Construction: Heavy-duty seamless steel tubing

• Finish: Powder-coated, corrosion-resistant black coating

• Manufacturing Features:

  • Reinforced weld lines for durability

  • Cylindrical design for even force distribution

  • Smooth exterior for reduced friction during operation

  • Engineered ends for tight hydraulic or mechanical fit

Compatible Caterpillar Models

The 7C2991 EJECTOR AS CATERPILLAR is a specialized component compatible with a range of Caterpillar ejector-type articulated and rigid frame trucks. This part is most commonly found in large-scale machines used in mining and bulk earthmoving projects.

Confirmed compatibility includes:

• Caterpillar 631D – Ejector Scraper

• Caterpillar 631E – Ejector Scraper

• Caterpillar 637D – Ejector Scraper

• Caterpillar 637E – Ejector Scraper

This part is typically integrated into the scraper bowl where it works in tandem with the hydraulic cylinder to push material out evenly during the discharge phase.

Functionality and Importance

The ejector assembly is critical for the effective clearing of the scraper bowl. A worn, damaged, or misaligned ejector can lead to material buildup, inefficient unloading, and increased wear on the machine’s hydraulic system. The 7C2991 EJECTOR AS CATERPILLAR ensures:

• Even Material Discharge – Its cylindrical form allows for uniform pressure distribution across the material, preventing partial ejections.

• Reduced Residue – Helps clear the entire scraper bowl, minimizing carryback and improving cycle time.

• Prolonged Machine Life – By facilitating clean ejection, it reduces stress on the bowl and hydraulic components.

• Efficient Energy Use – Proper ejection translates to less resistance, saving energy during the dump process.

Installation & Maintenance

The 7C2991 EJECTOR AS CATERPILLAR is a bolt-on replacement part. Installation should be conducted by experienced technicians, as it requires proper alignment with the hydraulic cylinder arms and scraper frame. Once installed, it operates with minimal maintenance, though regular inspections for weld integrity, surface corrosion, and hydraulic interface wear are advised.

Its corrosion-resistant black finish minimizes oxidation and moisture damage, especially important in wet, acidic, or abrasive environments.
