Repair Instructions




+What is the Difference between 8801X and 8801N?

The 8801X is a remanufactured fan clutch and has a core charge associated with it. The 8801N is a new fan clutch and does not have a core charge. The 8801N also has the added benefit of an interchangeable pilot, meaning that it can handle both 2.56” AND 5” fan pilots. The 8801X has only a 2.56” fan pilot.

+Do I need to replace my pulley bearings when replacing my Kysor-style fan clutch?

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.

+How do I determine which rebuild kit to use for my Kysor-style fan clutch?

Simply click here to identify which rebuild kit to use for your Kysor-style fan clutch.

+I have an aluminum body Kysor-style fan clutch. What are my rebuild/replacement options?

There currently is not a rebuild kit for the aluminum body Kysor-style fan clutches. These fan clutches should be replaced with Kit Masters’ 8801N fan clutch or BorgWarner’s part number 1090-09750-01.

+I'm replacing an aluminum body Kysor-style fan clutch. Do I need to replace my fan?

You do not need to replace your fan if you’re replacing your aluminum fan clutch with an 8801N. Our 8801N has an interchangeable pilot, meaning that it can handle both 2.56” AND 5” fan pilots.

+The black plastic coupler between my fan clutch and hub is melted or deformed. What causes this?

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.

+Where do I find the part number on my Kysor-style fan clutch assembly?

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. For more information regarding Kysor-style fan clutch identification, click here.
