Subject: Support bearing may allow Cooling Fan to move towards radiator
Some of the units listed above may have an insufficient press fit between the bearing and
hub that support the engine cooling fan. This may allow the fan to move towards the
radiator and create belt misalignment. The design of this assembly now includes a
capscrew to assist the press fit in retaining the parts in position. The conversion parts and
installation instructions for the improved design are listed below.
If you notice the issue identified above during the normal warranty time frame specified in
your Owners’ Manual, contact the local Toro distributor in your area for assistance.
