New Features

The SMC Axle Clutch was improved for the 1998 racing season.  Six changes were made for the sake of speed and durability.

1. The new housing is machined from a single piece of aluminum.  Compared to the former two piece assembly, the various diameters are almost perfectly concentric.

2. The studs are machined from a stronger steel and heat treated.

3. The link has a continuous 180° bend instead of the two 90° bends for greater strength.

4. The pressure plate is made of bronze instead of steel for smoother engagements and reduced wear.

5. A washer located between the primary weights and splines prevents damage to both if the clutch is improperly adjusted.

6. The speed collar is now equipped with a ball bearing.  Wear on both the shaft and the speed collar is eliminated.  The added support also extends the life of the main bearing.
