Twin Disc MG506 Marine Transmission Parts – Gear Bearing Kit Catalog

The Twin Disc MG506 marine transmission is a trusted workhorse in the marine industry, known for its compact design, smooth shifting, and long-lasting reliability. Whether installed in commercial fishing vessels, tugboats, or pleasure craft, it delivers dependable torque transfer and efficient propulsion. Over time, however, internal components such as bearings, gaskets, and seals naturally wear down. To restore performance and extend the life of your transmission, Diesel Pro Power offers precision-engineered kits designed specifically for the Twin Disc MG506 and MG506-1 models.

Bearing Kit for Twin Disc MG506 Marine Transmission

The bearing kit for the Twin Disc MG506 includes all the critical internal bearings needed to support the gearbox’s rotating assemblies. These bearings ensure smooth operation and proper alignment of the input and output shafts — essential for maintaining optimal gear engagement and minimizing vibration.

• Application: Designed for MG506 transmissions with gear ratios ranging from 1.50 to 2.50.

• Purpose: Replaces all major internal bearings, restoring precision and reducing wear.

• Material Quality: Constructed from high-strength, heat-resistant steel suitable for continuous marine operation.

• Functionality: Maintains the correct spacing between gears, preventing internal friction and improving oil flow.

This bearing kit is ideal for comprehensive maintenance or full overhauls. Each bearing is manufactured to match the original Twin Disc design, ensuring consistent performance and longevity. Whether you’re performing preventive maintenance or responding to signs of wear, this kit provides the reliability needed to keep your MG506 transmission running smoothly in harsh marine conditions.

Gasket and Seal Kit for Twin Disc MG506 & MG506-1

To complement the bearing kit, the Twin Disc Gasket and Seal Kit provides a complete set of high-quality gaskets, O-rings, and seals required to reseal the transmission during reassembly.

• Compatibility: Fits both MG506 and MG506-1 transmissions.

• Contents: Includes input and output shaft seals, case gaskets, and inspection plate seals.

• Material: Built from marine-grade, oil- and heat-resistant materials designed to handle the high pressures inside a marine gearbox.

• Protection: Prevents oil leaks, protects against seawater intrusion, and keeps the internal components properly lubricated.

Replacing gaskets and seals during a bearing service helps ensure your transmission remains tight and leak-free. Over time, exposure to heat and oil causes seals to lose elasticity, increasing the risk of leaks and contamination. A complete gasket and seal replacement restores the transmission’s integrity and helps avoid future repairs.

Comprehensive MG506 Maintenance Solution

Using the bearing kit together with the gasket and seal kit provides a total solution for renewing the MG506 marine gearbox. Together, these two kits:

• Improve internal oil retention and pressure.

• Reduce noise and vibration.

• Extend transmission life by maintaining precise shaft alignment.

• Prevent leaks and contamination that could lead to costly damage.

Each kit is designed for precise fitment, minimizing downtime during rebuilds. Marine operators and technicians can rely on Diesel Pro Power’s inventory to source all required components for a full MG506 refresh from a single, dependable supplier.
