Steve Hannes: First the small shaft (Driven). It is now on the right in this picture. It is a solid shaft containing two gears, the upper gear gets its drive from the main shaft, transferred to the bevel gear just visible at the base of the shaft. Again, this is the torque delivery (the 60%) to the rear wheels. Now for the larger shaft assembly (on the left in this pic). This assembly has a lot going on. In this picture I've removed the upper assembly. It now is positioned in the forefront and turned upside down. It is the sealed viscous coupler unit. It is driven on the mainshaft by four dowel pins and resides right above the mating primary drive gear for the rear wheels. ***** more info: http://jagmotorproject.blogspot.com/2007/02/motor-project-17-transfer-time.html *****
