DIY Crank Shaft Pulley
Step 2


Now it's time for the hard stuff!

The first thing you need to do is remove the water pump pulley for more access to the crank pulley. This is done by removing the 4-10mm bolts.

The next thing to remove is the extra AC pulley that is attached to the crank pulley. This is the hard one!
It has 3-10mm bolts that are hard to reach and even harder to get a socket on them. The best tool for this is a small 1/4" breaker bar with the smallest 10mm socket you can find! Once the bolts are loose, you can use your fingers to remove them and pull off the pulley.

Now it's time to decide how you are going to loosen the pulley bolt.

Some people use the engine starter and crank the engine over and use the engine's torque to break the bolt free.

The easiest way I've heard of locking the engine is to put the car in 4th gear with the emergency brake on. This should lock everything up enough to loosen and tighten the bolt.

I decided to pull off the clutch cover and use the flywheel tool to lock the flywheel. This will add an extra half hour of work.

Now it's time to break the bolt loose! Getting the socket and wrench onto the bolt was painful and difficult. There is only about 2.5" of space to work with, and most 1/2" sockets are about 2" long, so that leaves about 1/2" for the rachet. Hopefully you created the special shortened socket that I talked about in the intro page!


Once I got the socket on, I used a four foot pipe extension to break the bolt loose. It makes a pretty good knock when it breaks loose!

The next problem I ran into was actually removing the bolt. If you did not make the short socket, then you will most likely run into this problem. If I loosened the bolt to much, I couldn't get the wrench and socket off. There wasn't enough room! So I decided to leave the socket on the bolt and use a pipe wrench to turn the socket.

Once the bolt comes out, you can use a large screwdriver to pry the pulley off of the crank.
