Key Features and Specifications

This replacement drive boasts a 2.4:1 gear reduction, providing a final reduction of 72:1 for increased pulling power and improved speed control.

This combination ensures a smooth and responsive performance, making it ideal for both casual operating and more demanding scenarios.
  • Enhanced Pulling Power: The 72:1 reduction ratio significantly increases the locomotive's ability to pull heavy loads.
  • Improved Speed Range: The high RPM motor allows for a wider speed range, accommodating various operating conditions.

Installation and Maintenance

Installation of the The Ultimate Balboa/cb C-21 Replacement Drive Trial Pack [8J4S0i6x] is straightforward, as it is designed to fit the existing mounting plate using the original screws. However, due to the age of the models, it is recommended to perform some maintenance tasks before installation. This includes careful cleaning and lubrication to ensure smooth operation, as well as gentle filing of the slot on the bottom of the boiler to accommodate the new drive. By taking these precautions, you can ensure a long-lasting and trouble-free performance from your upgraded locomotive.
