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.
