How To Manually Lock A Horton Fan Clutch

Locking a Horton fan clutch manually can be a difficult task, but it is important to ensure the fan clutch is properly secured. Taking the proper steps to secure the fan clutch will help avoid any unnecessary damage to your vehicle. This guide provides step-by-step instructions for manually locking a Horton fan clutch, from setting up removal tools and loosening nuts and washers to installing new release bearings and securing the fan clutch on your vehicle.


Before beginning the locking process, its important to familiarize yourself with the components of Horton fan clutches. The components include an inner bearing, outer bearing, an adjustable tensioner, and a locking nut. The inner bearing is responsible for allowing the fan blade to rotate while the outer bearing provides additional support and stability. The adjustable tensioner allows you to adjust the level of friction between the inner and outer bearings while the locking nut keeps everything securely in place.

Manual Locking Procedure

In order to lock a Horton fan clutch manually, you will need a few tools including pliers or wrenches, screwdrivers, and possibly some lubricant or thread sealant depending on your model of fan clutch.

Step One: Setup Removal Tools

Start by gathering all of your necessary tools for removal: pliers or wrenches (depending on your model), screwdrivers, and possibly some lubricant or thread sealant depending on your model of fan clutch. Once you have all of these items together, you can begin loosening nuts and washers that secure the fan clutch in place.

Step Two: Loosen Nut and Washers

Next, use pliers or wrenches (depending on your model) to loosen both nuts and washers that secure the fan clutch in place. In some cases you may need to use thread sealant as well in order to ensure a tight fit when reattaching these pieces later on. Once this step is complete you can move onto releasing existing bearings.

Release Bearing Replacement

To replace existing release bearings youll first need to remove both upper and lower bearing assemblies from their respective housings before proceeding with installation of new ones. To do so use pliers or wrenches (depending on your model) carefully unscrewing each assembly from its housing before attempting to install new ones in their place.

Upper Bearing Removal

Begin by removing upper release bearing assembly first using pliers or wrenches (depending on your model). Carefully unscrew each component until it is free from its housing before continuing onto lower bearing removal if necessary. Be sure not to force anything as this could cause damage to other components nearby.

Lower Bearing Removal

Once upper bearing assembly has been removed from its housing proceed with removal of lower one using same method as above if necessary. Again take care not force anything as this could lead additional damage other components nearby during removal process so proceed cautiously when working with these parts!

Installing New Release Bearings

Now that existing release bearings have been removed its time install new ones in their place! Start by verifying gap between inner and outer bearings using feeler gauge before adjusting accordingly if needed; once gap has been verified proceed with installation instructions provided below:
