The Challenge:
Risky and costly steering
arm bearing maintenance
Routine maintenance on haul truck steering components in demanding terrains can be a challenging yet critical process.
Traditional methods for removing and installing split shell bearings and ball studs are a known bottleneck for maintenance teams, often posing significant safety risks and operational inefficiencies.
- Risk of bearing splaying, fracturing, and unpredictable ejection during extraction.
- Potential for manual handling injuries while hammering components, alongside dangerous labour practices
- Misalignment during installation.
- Multiple tools, heavy impacts, and strenuous manual labour lead to slower changeouts
- Increased truck downtime, disrupting maintenance schedules and operational targets.
- Aggressive removal and installation methods frequently damage bearings, ball studs, and surrounding assets.
- Leads to added costs and compromising component integrity.

The Solution:
Simplified and Safer
Steering Arm Maintenance
To overcome the risks, delays, and costs of traditional bearing changeouts, Geographe’s Ball Stud Bearing Installation and Removal Tool (BSBIRT) offers a professional, engineered solution.
The BSBIRT transforms this critical maintenance task into a safe, efficient, and precise process, directly addressing the known problems maintainers routinely face on Caterpillar 785, 789 & 793 haul trucks.
Enhanced Safety
- BSBIRT’s controlled hydraulic operation eliminates the need for hammering and dangerous manual force.
- Prevents unpredictable component ejection, fractures, and the risk of manual handling injuries.
- Ensures technician safety is the top priority.
Maximum Efficiency & Uptime
- Replaces multiple tools and strenuous labour with a single, powerful tool.
- The BSBIRT delivers faster, standardised changeouts that directly translate to reduced truck downtime.
- Result is more productive maintenance schedules.
Total Asset Protection
- BSBIRT's built-in guidance system ensures precise alignment for both removal and installation.
- Controlled, non-aggressive maintenance method protects bearings, ball studs, and surrounding components from damage.
- Helps preserve the integrity of valuable assets.
How it Works

Traditional methods for removing worn split shell bearings on ball studs often pose significant safety challenges, including the risk of bearing splaying, fracturing, and unpredictable ejection during extraction.
These risks not only endanger maintenance teams but also result in inefficient and hazardous removal processes, which may damage equipment and surrounding assets.
The BSBIRT tool addresses these issues by prioritising user protection and operational safety.

When inserting the ball stud, the BSBIRT is designed to efficiently set the stud on the spacer, allowing the operator to keep their hands clear of potential pinch points or crush zones.

Installing new split shell bearings on ball studs using traditional methods presents safety hazards due to dangerous labour practices, strenuous manual labour and potential misalignment.
In addition, the BSBIRT improves this process by allowing quick rotation and placement. By applying hydraulic pressure and exact component alignment, it minimises the risk of injury to maintenance teams and damage to surrounding assets.
