Unrivaled quality and performance in an easy to install rebuild kit. The GoldTop by Kit Masters is the ultimate fan clutch rebuild kit. Auto Lock feature prevents on-the-road failures. The 14-256-1 features a 2.56” fan pilot and one pulley bearing.
3 Year/300,000 Mile Warranty
The key reason for premature spring-engaged fan clutch failures is LACK OF TORQUE. There are fan blades in operation today that require more torque than current fan clutches can produce.
Our GoldTop fan clutches pack over 5,000 inch-lbs of torque. Enough to handle nearly any size fan blade.
Kit Masters’ patented Auto Lock feature will AUTOMATICALLY LOCK UP fan clutches when the friction material nears the end of its life, allowing the vehicle to finish its trip.
Repair or replace the fan clutch in your shop, at your convenience. No outside labor costs or tow bills.
All GoldTop fan clutches are backed by Kit Masters’ rock-solid, unmatched 3 year / 300,000 mile warranty. No other Kysor-style fan clutch warranty comes close.

The difference between GoldTop part numbers 14-256 and 14-256-1 is the bearings. Part number 14-256 contains two 6209 bearings, while part number 14-256-1 contains one 3209 bearing. These bearings are not interchangeable.
In order for a GoldTop fan clutch to operate properly, there must be between 90 – 120 psi of air pressure going into the fan clutch. This means the air pressure must be tested at the end of the air line, where it connects to the fan clutch. The compressor\’s pressure gauge does not accurately show how much air pressure is actually entering the fan clutch.
There are several different pulley bearing configurations that you will find when rebuilding Horton® DriveMaster® fan clutches. Regardless of the number of bearings or the configuration of them, you will ALWAYS save and re-use any bearing spacers that come out of your original fan clutch. When installing bearing spacers, always place them between the bearings.
NOTE: Bearing spacers always come in pairs – one for the inner race and one for the outer race. You should never install only one spacer.
Quite often, the T-55 torx bolt, also known as the “jack bolt”, on the front of a DriveMaster® fan clutch will become stuck and you will not be able to loosen it. To solve this problem, first try applying heat to the bolt. If that does not work, use a 2 1/4” hole saw to cut the fan plate around the jack bolt. This will allow you to remove the fan plate and then access the friction screws. To see a demonstration, click here.
If your GoldTop fan clutch assembly bottoms out, or doesn’t fit into the pulley, there are a couple of things to check:
1. Did you re-install the air chamber cap? If you re-install the air chamber cap (the coaster-shaped disc that was in front of the air cartridge) that you took out during disassembly, your GoldTop will not fit properly. The air chamber cap should be discarded during disassembly.
2. Are you installing the GoldTop on an International truck? Some Internationals have a modular fan clutch system that requires it to be installed on the truck one piece at a time. If you have one of these fan clutches, you will need an adapter, part number 24-4700.
There are several different bearing configurations that you will find when rebuilding Horton® DriveMaster® fan clutches. To ensure that you install the proper replacement bearings and spacers, refer to this chart.
Before deciding if you will be able to rebuild your fan clutch, you will need to assess it. There are several points to inspect:
« Make sure the pulley is not chipped or damaged. If it is damaged enough to cause damage to the belt, the fan clutch will not be rebuildable.
« Make sure the bracket is not broken or cracked. If it is, the fan clutch will not be rebuildable.
« Check to see if the shaft is worn. A shaft that has been damaged or worn from the pulley bearings will result in repeat bearing failure.
« Check the inside of the pulley. Inspect to see if it is worn or damaged from the pulley bearings.
If the bracket, shaft and pulley are all in acceptable condition, you will be able to rebuild your fan clutch.
First, check your air pressure right at the entry point of your fan clutch. You need a minimum of 90 psi, right at the entry point of your fan clutch, in order for it to operate correctly.
If you have more than 90 psi, right at the entry point of your fan clutch, and your fan clutch still won’t disengage, the Auto Lock feature on your fan clutch has kicked in.
If you have more than 90 psi, right at the entry point of your fan clutch, and your fan clutch still won’t disengage, the Auto Lock feature on your fan clutch has kicked in. When your friction material nears the end of its life, the Auto Lock feature fully engages your fan clutch to help you get to a service shop to get your fan clutch maintained, instead of leaving you stranded on the side of the road. Your fan clutch needs to be rebuilt or replaced.
When you installed your pulley bearings, you most likely did not install your inner race bearing spacer, which should always be installed along with the outside race bearing spacer. If you do not install the inner race bearing spacer, when the 2” bearing nut is torqued down on the shaft, it pre-loads the inner race of the bearings causing them to prematurely fail.
The air cartridge is not mating correctly against the bottom of the GoldTop. Inspect the carbon on the air cartridge. Replace your air cartridge if needed.
When your fan clutch won’t engage, this usually means that your GoldTop is out of friction. To test this, shut off your truck and try to spin your fan blade. If you can spin your fan blade, then you have no friction left and your fan clutch assembly needs to be rebuilt or replaced. If your fan blade does not spin, your fan clutch is properly engaged. GoldTop fan clutches engage when there is no air reaching the fan clutch.
No, GoldTop kits only rebuild Horton® DriveMaster® style fan clutch assemblies. There may, however, be a newer style remanufactured fan clutch available that can replace your HT/S style fan clutch. Contact Kit Masters customer service to see if this is an option. You would also need to change out your solenoid valve with this conversion because the Horton® HT/S style fan clutches are –air-to-engage” and GoldTop fan clutches are –air-to-disengage.”
California Residents: Prop 65 Warning
You are purchasing a Kysor-style fan clutch. When replacing a Kysor-style fan clutch, you must always replace the hub (pulley) bearings at the same time. Failure to do so will void the warranty on your fan clutch.
To determine the required bearing kit for your hub, enter the hub part number in the search field below, find the part number of the bearing kit you need on the dropdown below, or click on the 'Learn More' link below.
I don't want to purchase a hub bearing kit at this time.
Failure to install new hub bearings with your clutch will void your warranty.
This product includes a core charge. You may pre-pay for the freight to return your core during the checkout process, or ship using your own method. Core returns must be received by Kit Masters within 30 days of purchase.
