Yes. To maintain your product warranty, whenever you replace a Kysor-style fan clutch you must also replace the pulley bearings. Quite often, the pulley bearings are what caused the old fan clutch to fail in the first place. Replacing the fan clutch without replacing the pulley bearings will most likely cause the new fan clutch to fail as well.
This is caused by pulley bearing failure. Replace the pulley bearings. You may need to replace the seals in your fan clutch as well. A new black coupler will come in both the fan clutch seal kit and the bearing kit.
The entire fan clutch assembly part number is usually on a sticker on the mounting bracket or on the pulley. If the sticker is missing, we may be able to identify which fan hub assembly you have based on the casting number on the mounting bracket.
