The 910E and Its Place in Caterpillar’s Loader Lineage
The Caterpillar 910E wheel loader was part of a transitional generation of compact loaders produced in the late 1980s and early 1990s. Designed for municipal work, light construction, and aggregate handling, the 910E offered a balance of maneuverability and lifting power. With an operating weight of roughly 12,000 to 13,000 lbs and a bucket capacity of around 1.5 cubic yards, it filled a niche between skid steers and full-size loaders.
Caterpillar’s E-series loaders were known for their mechanical simplicity and robust frames. The 910E featured a torque converter transmission, Z-bar linkage for bucket control, and a rear-mounted counterweight system to stabilize the machine during lifting operations.
Counterweight Design and Placement
On the 910E, the counterweights are mounted on either side of the rear frame, flanking the engine compartment. These cast steel blocks are bolted directly to the loader’s chassis and serve to offset the forward tipping moment created when the bucket is loaded. Without adequate rear ballast, the machine risks instability, especially when lifting heavy material or operating on uneven terrain.
The counterweights are not just passive mass—they are engineered to distribute weight evenly across the rear axle and maintain traction during bucket operation. Their placement also allows for easy removal or replacement during transport or servicing.
Weight Specifications and Part Identification
Each counterweight on the 910E, identified by part number 8R8132X, weighs approximately 480 pounds. With two installed on the machine, the total rear ballast adds 960 pounds to the loader’s frame. This mass is critical for maintaining balance when the bucket is fully loaded, especially in high-lift scenarios or when using forks for palletized material.
The part number itself—8R8132X—indicates a discontinued component, meaning replacements may be difficult to source through standard dealer channels. Operators are advised to retain original counterweights and avoid removal unless necessary for transport or repair.
Operational Impact and Safety Considerations
Removing or losing a counterweight can significantly alter the machine’s center of gravity. Operators may notice:
Replacement Challenges and Fabrication Options
Since the 8R8132X counterweight is no longer in production, sourcing replacements requires creativity. Options include:
Conclusion
The counterweights on the Caterpillar 910E are more than just heavy blocks—they are precision components designed to stabilize the machine and ensure safe operation. At 480 pounds each, they play a vital role in maintaining balance and traction. With the original part discontinued, operators must take care to preserve existing weights or pursue accurate replacements through salvage or fabrication.

Operational Impact and Safety Considerations
Removing or losing a counterweight can significantly alter the machine’s center of gravity. Operators may notice:
- Reduced rear traction during bucket lift
- Increased risk of tipping forward
- Poor stability on slopes or uneven ground
- Excessive front tire wear due to imbalance
Replacement Challenges and Fabrication Options
Since the 8R8132X counterweight is no longer in production, sourcing replacements requires creativity. Options include:
- Contacting salvage yards specializing in older Caterpillar equipment
- Fabricating a steel block to match the original dimensions and bolt pattern
- Using concrete-filled molds with embedded steel plates for mounting
- Consulting with aftermarket suppliers who may offer compatible ballast kits
