Truck operators and mechanics face several hurdles when sourcing Eaton transmission parts:
Identifying the Correct Part: With models ranging from 5-speed to 18-speed, finding the right part (e.g., a synchronizer for an RTLO-18913A) can be daunting.
Cost Concerns: Balancing upfront costs with long-term reliability is critical, especially for fleets managing tight budgets.
Avoiding Counterfeits: Low-quality aftermarket parts can lead to premature failures and costly repairs.
Real-World Example: A fleet manager in Georgia recently faced a week-long delay because they ordered an incompatible countershaft gear for an FR-15210B model. Using Eaton’s official tools could have saved them $2,000 in downtime costs. At Volgen Power, we simplify the process with expert support and a curated Eaton parts catalog.
Eaton’s parts catalog covers over 700 unique components, including rebuild kits, bearings, and gaskets, with 95% of parts available for same-day shipping through trusted suppliers like Global Drivetrain Supply.
Step-by-Step Guide to Finding the Right Eaton Transmission Parts
Finding the perfect Eaton Fuller transmission part is straightforward with the right approach. Follow these steps to ensure accuracy and efficiency, backed by expert insights.
Step 1: Identify Your Transmission Model
Locate your truck’s VIN or transmission serial number (found on the driver’s side of the housing). Common Eaton models include RTLO-18913A, FR-15210B, and RT-9513. Expert Tip: Keep a maintenance log with your model and serial number for quick reference.
Step 2: Use Eaton’s Inforanger Tool
Access Eaton’s Inforanger platform, enter your model number, and retrieve exact part numbers (e.g., shift fork for RTLO-16913A: part #K-3422). Pro Tip: Download Eaton’s parts catalog PDF for a comprehensive offline reference.
Step 3: Consult a Trusted Supplier
Volgen Power’s parts lookup tool and expert team simplify the process. Contact us for personalized guidance or browse our model-specific inventory. Expert Tip: Verify supplier credibility to avoid counterfeit parts.
Step 4: Verify Compatibility
Cross-check part numbers using Eaton’s catalog or consult Volgen Power to prevent costly errors. Pro Tip: Check if your transmission is under warranty for potential cost savings.
Troubleshooting Common Issues

- Vibration/Noise: Inspect the input shaft (part #4301109) or bearing kit (part #K-3454).
- Leaking Fluid: Check seals or consider a rebuild kit.
Expert Advice: If unsure, consult a mechanic or Volgen Power before ordering.
