Fan Clutch Rebuilds

Fan Clutch Rebuilds

When the time comes and your fan clutch fails, you will need to make a decision. Should you purchase a rebuild kit and rebuild the fan clutch yourself, or a complete fan clutch assembly to replace your old one? Ask around and you’ll likely get split advice on this. It turns out that there is no right answer to this question. However, you will want to choose the option that fits your situation (including your budget) best.

WHY DID THE FAN CLUTCH FAIL?

The first thing you need to know before you choose between a rebuild kit or a complete assembly is what happened to your current fan clutch. There are several types of failures that can happen, and knowing which one can help you determine how to proceed.

FRICTION FAILURE – This happens when the friction material is worn down to the point where it cannot engage anymore. This can happen from normal long-term wear, or it can be caused by an underlying issue, like an air leak. If your friction has failed, rebuilding or replacing are both viable options.

PULLEY BEARING FAILURE – Much like failed friction material, this can either be from normal long-term wear, or from some underlying issue. Also, heat is generated by slipping friction material due to a lack of torque. As long as the failed bearings didn’t damage the pulley shaft, you still have the option to either rebuild or replace the fan clutch.

CATASTROPHIC FAILURE – This can happen for several reasons. But if your fan clutch failure ends in a cracked or chipped pulley, a worn pulley shaft, or a damaged/broken mounting bracket, your only option will be to replace the fan clutch.

WHEN TO REBUILD

Compared to the price of a complete assembly (new or reman), a rebuild kit is a very appealing option when dealing with a failed fan clutch. The cost of a new one, depending on the model, can vary but can reach upwards of $2,000. Remans can cost significantly less but are still a fair amount more than a rebuild kit. This is where the appeal of a rebuild kit comes in. With a little effort, your fan clutch can be rebuilt to meet or exceed OEM standards while saving you some money in the process.

A common misconception is that rebuilding a fan clutch is a labor-intensive, time-consuming task. However, with a little bit of knowledge and some hands-on effort, the rebuilding process can be fairly straightforward.

Another benefit of rebuild kits is their availability. While there are thousands of models out there, most of them fall into one of a few categories. Each of these categories can be covered by a single rebuild kit, meaning that you can keep just a handful of kits on hand and be able to rebuild the majority of fan clutches in the market. When one of these fan clutches fails, you have the option of either ordering a replacement, which will most likely need to come from the factory with an unknown lead time or if you have the rebuild kit on hand, you can rebuild it right on the spot. This ultimately leads to more uptime.

Pros of Rebuilding:

  • Versatility (can rebuild many different models with a single kit)
  • Less expensive
  • Instant availability (if kept on hand)

Cons of Rebuilding:

  • Possible installation errors
  • More hands-on time

WHEN TO REPLACE

While rebuilding a fan clutch is not a difficult process, sometimes you might want to opt for simply replacing your fan clutch. Maybe your old one has reached the end of its life altogether – the pulley shaft is worn, or the pulley is broken – and it can’t be rebuilt. Or maybe you just don’t have the time to rebuild the fan clutch. In these cases, purchasing a complete assembly can be the right decision.

The benefit to purchasing a complete assembly is that once you receive the new fan clutch, you simply need to take the old one off. Then bolt the new one on in its place, verify your air pressure and you’re all set. You also get the benefit of having a factory-built fan clutch that was assembled by a trained professional, eliminating the possibility of an installation error.

The downfall of ordering a complete assembly is that unless you have a very common model, you probably won’t be able to find one locally. This means it will have to be ordered from the manufacturer, which can mean a day or two of downtime while you wait for the part.

Pros of Replacing:

  • The manufacturer does the work
  • Fast Installation
  • Eliminate the chance of errors

Cons of Replacing:

  • More expensive
  • Delayed availability
