How Do You Remove a Pulley Sheave?
Assuming you are talking about a V-belt pulley:There are four main bolts holding the sheave halves together. Two bolts go through the hub on one side of the sheave, and the other two go through the boss on the other side.
The bolts are tightened down with retaining washers and nuts. To remove the sheave, these four bolts must be loosened. This can be done by heating up the bolt heads with a torch to expand them, then using an impact wrench to loosen the nuts.
Once all four bolts are loose, the halves of the sheave can be separated and removed from the shaft.
How Do You Loosen a Seized Pulley?
If your car has a seized pulley, it can be a real pain to try and loosen it. There are a few methods you can try, but unfortunately, there is no guarantee that any of them will work. However, it is worth a shot to try one or all of the following methods before resorting to replacing the entire pulley system.
One method is to use WD-40 or another type of penetrating oil. Spray the oil onto the seized pulley and let it sit for at least an hour if not longer. After letting the oil penetrate, try moving the pulley back and forth to see if it will budge.
If it does move, continue spraying WD-40 on it and moving it back and forth until the seized Pulley comes loose.Another method that can be used is heating up the area around the seized pulley with a blow torch. Be careful not to heat up the surrounding areas too much as you don’t want to damage anything else on your car.
Heat up the area for about 30 seconds then stop and let it cool down for 30 seconds. Repeat this process 3-4 times then try moving the Pulley back and forth again. The heat may have expanded whatever was causing the seizure enough that you can now loosen it.
A third method is similar to using WD-40 except you use Coca Cola instead. Pour some Coke over the affected area and let sit for at least an hour before trying to move the Pulley back and forth again. The acid in Coke can sometimes eat away at whatever is causing seize making it easier to loosen.
As I said, there is no guarantee that any of these methods will work but they are definitely worth a shot before having to replace an entire pulley system which can be quite costly!
