But if you are looking for how to remove the alternator clutch pulley without tool then I will share some tips on how you can do this without any special tool because the process requires tools. However, you can perform the tasks with a very minimal tool.
So, in this guide, I will cover everything necessary to remove and replace an alternator freewheel clutch pulley. And we will also clutch the pulley function or purpose the common problems associated with it.
What is an alternator clutch pulley?
An alternator clutch pulley, also known as a freewheel clutch pulley, is a vital part of a vehicle’s alternator. Located at the front side of the alternator, which is connected to the alternator drive belt. The clutch pulley helps keep your car engine running efficiently because it presents a freewheel mechanism that helps rotate in one direction without spinning the alternator.
This is especially valuable especially when the engine is idling, as it keeps the alternator producing power without overworking itself. At higher engine speeds, the alternator clutch pulley engages with the alternator, causing it to spin and generate electricity.
This integral component of your car’s charging system plays a significant role in its overall performance; its proper functioning ensures optimal efficiency throughout all stages of driving.
The Purpose of Alternator Clutch Pulleys
Alternator clutch pulleys were designed to prevent belt slip and extend the life of a vehicle’s alternator. These pulleys have dog clutches inside them that catch one way and then freewheel in the other direction for smooth operation.
And this also reduces belt slip while keeping your alternator spinning slowly – helping it avoid overloading.
Problems Associated with Alternator Clutch Pulleys
Alternator clutch pulleys offer many advantages, but they may also lead to problems. One common issue is the failure of the pulley itself due to wear and tear or incorrect installation.
Another issue is noise caused when engaging and disengaging the clutch pulley – this noise could indicate an underlying issue with its workings.
Tool Needed for Removing Alternator Clutch Pulleys
A pulley holder is necessary to safely remove an alternator clutch pulley. This tool holds the pulley in place while you loosen its nut attachment to the alternator. The teeth of this tool grip onto the pulley, keeping it from spinning while you loosen its nut.
How to Take Out Alternator Clutch Pulleys
In order to remove an alternator clutch pulley, you will need a special tool called a pulley holder.
This holds the pulley in place while you loosen its nut attachment on the alternator. Once loosed, use an impact wrench to free the pulley.
Before doing so, make sure that all plastic covers have been taken off, which protects them from dirt and debris.
Alternator Clutch Pulleys: should you Keep or Dispose of them?
Overall, your car’s alternator clutch pulleys offer many benefits to vehicle owners, such as preventing belt slip and extending the life of an alternator.
But they may also cause issues like failure and noise if left unused. Removing them eliminates that risk, providing smoother operation overall.
Ultimately though, it is up to each vehicle owner whether to keep or replace their clutch pulley; it is important that they carefully consider both pros and cons before making a final decision.
How to remove alternator clutch pulley without tool
So if you are looking for how to remove the alternator clutch pulley without a tool, I would like to say that it is really not possible to remove a vehicles alternator clutch pulley without a tool, and that is because, at every step of the way, you will different set of tools be it a screwdriver or wrenches to be able to take out the clutch pulley.
With that said, here are the step on how to remove the alternator clutch pulley with the required tool. You may watch the video above to see how this is done; otherwise, keep reading for the 2 ways you can remove the alternator clutch pulley without using any special tool.
How to remove alternator clutch pulley without using a special tool
Removing an alternator clutch pulley without the aid of a tool is not possible, but you can try. So normally, the clutch pulleys are fastened in place with either large bolts or retaining clips. And to remove those clips, you will need either a Socket/Ratchet or a Wrench.
So if you have got these tools, here are a few methods you can try without using any other special tool because for me these are the most basic tools, and you can even borrow from your neighbor:
Alternator clutch removal without using a special tool
1. Using a Socket and Ratchet
One of the simplest methods to remove alternator pulley without an impact wrench is by using a socket and ratchet. Select a socket that fits the pulley bolt, then turn it counterclockwise with the ratchet to loosen it and free up your hands for easier removal of the clutch pulley. Be careful not to strip either the bolt or threads during this process.
2. Using a Wrench
If you don’t have access to a socket and ratchet set, you can also use a wrench to take out the alternator clutch pulley. Find a wrench that fits the bolt, then turn it counterclockwise – this may take more effort than using a socket and ratchet combo, but it is possible.
If you don’t have access to any of the tools above, then you can try to use a flathead screwdriver to pry the retaining clip holding your clutch pulley out of its groove. Be careful when performing these tasks so that all pieces come off at once!
- Note that these methods may not work for all types of alternator clutch pulleys, and you may require a specialized tool in some instances. Consult a professional mechanic for assistance if you’re still uncertain how to take out your alternator’s clutch pulley y, or you can watch the video above as that will show where to screw and where not to. That is how you remove the alternator pulley without an impact wrench.
How to remove alternator clutch pulley with tool
Step 1. Get the Necessary Tools
Before beginning the removal process, it’s essential to collect all necessary tools. An alternator freewheel puller remover set will do the trick as it includes parts for various pulleys and alternators. For this particular pully, you will need an Allen extension, crown type key, 17mm wrench, and 10mm wrench – so be sure you have everything before beginning so as not to cause damage to either pulley or alternator.
Step 2. Block the Alternator Shaft and Insert Crown Type Key
To remove the alternator freewheel clutch pulley, you must first stop its rotation by using an allen extension (as you cannot hold onto the pulley while unscrewing). Then insert a crown-type key into its crown; this will enable you to grip it securely with a 17mm wrench as you unscrew from the alternator. With this key in place, it should become much easier to unscrew completely.
Step 3. Unscrew the Pulley with Wrenches
Once the crown-type key is inserted into the pulley, use a 17mm wrench to unscrew it from the alternator. Use a 10mm wrench to block the rotation of the shaft while unscrewing the pulley. If pulling is difficult, larger wrenches or levers may be necessary; just ensure not to apply too much pressure when doing so in order not to damage either pulley or alternator.
Step 4. Replace the Old Pulley with a New One
After you’ve successfully taken out the old pulley, it’s time to replace it with a new one. Refer to your manual for specific instructions on replacing this pulley. It is important not to use an impact wrench when doing this, as this could cause damage. Instead, use the same technique as before: block off the alternator shaft and tighten with a 17mm wrench at 85 Newton meters.
Step 5. Tighten the New Pulley and Place a Cup Over It
Once the new pulley is secured, tighten it using the same technique as before by blocking the alternator shaft and using a 17mm wrench to tighten it to 85 Newton meters. Finally, place a cup over it to protect it from dust and moisture accumulation, helping ensure the good condition of the pulley, which could extend its lifespan significantly.
Conclusion
Removing an alternator clutch pulley may seem intimidatingly complex, but with the proper tools and instructions, it can be done quickly and effortlessly.
As demonstrated in this article, using an alternator freewheel puller remover set along with appropriate wrenches makes the task straightforward.
It is essential to follow the manufacturer’s guidelines when replacing this pulley in order to guarantee its proper functioning and avoid damaging other components of your alternator.
By following the steps outlined here, you can confidently replace your alternator clutch pulley, saving yourself time and money on costly repairs in the future.
