Description

This is a longer axle length of the Motor-gearbox.  The axle measures 11.5″ end to end, including a longer land for the bearings.   Use these for custom installations.

PRN has been producing 24vDC axle mounted gearboxes to the hobby for years.  These assemblies come ready to run in 7.5″ gauge, just mount them in the trucks of your choice and wire them up

• Sealed unit with grease fitting for easy maintenance
  • 24v custom built high-power motor 1.5HP constant (1000 watts constant duty)
• Custom machined gearbox to maximize clearance and strength
