Ariens Company has learned that the engine pulley (p/n 07331600) and crankshaft spacer (p/n 04519200) used on the Pro-Turn models in the serial number ranges listed above may not be clamped tightly when the clutch is mounted. This possible condition is due to variances in the length of the engine crankshaft and the components mounted on the crankshaft.

To eliminate this condition, Ariens has created a clutch spacer kit p/n 59102100. This kit contains a new crankshaft spacer (p/n 04519200) and a new clutch mounting bolt (p/n 05900043). See Figure 1.

The new spacer is slightly longer than the original to ensure that the clutch, spacer, and engine pulley are clamped tightly when properly mounted on the crankshaft. The new spacer is gold in color so it can be easily distinguished from the original spacer which is black.

The new clutch-mounting hex bolt is ¼" longer than the original to ensure adequate thread engagement.
