Introduction

Transfer Case internal, Yamaha Road Star

 

This article is one of a series that describes how to disassemble, work on, and reassemble the Road Star engine. This particular article shows how to remove and tear down the transfer case assembly. See the Complete Engine Tear Down, Orientation article in this website for details.

Be sure you refer to the service manual through all phases of this project.

 

Understanding the Road Star's Power Transfer Systems

The Road Star's power is organized in three stages:

  • The Primary Drive consists of the gearing from the crankshaft to the transmission's drive axle.
  • The Middle Drive simply consists of a gear attached to the transmission's drive axle, a drive chain which turns a 'driven gear', which turns the middle driven shaft. The middle driven shaft is where the front drive-pulley attaches.
  • The Final Drive consists of the front drive-pulley, the drive belt, and the rear drive-pulley assembly.

This segment focuses on removing the transfer case, which houses the middle drive system, as well as the engine's oil tank.
