1992 Honda Prelude Crankshaft Pulley to loosen

[Winmechanic]

I am attempting to remove the crankshaft pulley. Anyone with

information as to whether it is clockwise to tighten and anticlockwise to loosen. I really would not want to ring the bolt.

It is standard threading and clockwise to tighten.

You can buy a tool that fits in the pulley and holds it while removing the bolt. I made one out of 1 1/2" Cast Iron Pipe pieces. I used a T-Fitting and installed a 1" reducer in the one side. The hex shape is just a hair over the pulley hex shape size. I just ground a little off of each flat side until it fit. I also added another reducer on the middle position and installed a 3 foot piece of 1" pipe as a handle.

Just so you know, I had a 3 foot extension on a 1/2" breaker bar that went inside the pipe and it took all I had to break the bolt loose. (jumped up and down on the pipe). I had to put a screw jack underneath the socket so that it would not fall out or strip the nut as I was jumping on it.

Or an easier way which is pretty much the same thing that he just told you. Just take a wrench, "a tork wrench if you have one" and get a metal pipe that's pretty long or something that's close to it, so you can get lot's of leveridge and you should be able to loosen it with your hands. If not just take something like the handle on a wrench and hit the pipe to loosen it. This should work, we just did this with my roommates car to get his crankshaft pulley off.

I would be VERY cautious of using a torque wrench for this task. Although they are large and give you much needed leverage, they are not usually designed for the type of torque that is needed to remove this bolt, especially in the loosening direction.

Also, at a minimum, this will compromise the torque calibration after using it like this. If it is used as a torque wrench later, it may be off considerably, causing improper assembly of other parts down the road. I know this because I did use my torque wrench for a similar task. Ended up snapping the inside of the head and replacement costs and calibration were far beyond the cost of another new one. If I would have used my SK ratchet and broke it, I could have taken it back and got a new one for free under warranty. Ended up having to buy a new torque wrench for $150.

Try to get someone with an impact wrench to break it loose for you, snug it tight and drive it home. There's a hole in the fenderwell to use a long extension on the nut. Using a pipe on a torque wrench is the best way to destroy the wrench.

I tried an impact using a very good Ingersoll Rand impact wrench with 600ft/lb torque, but it still did not budge. When I broke it loose with the breaker bars, I thought that I broke the wrench the way it snapped. After breaking it loose, I removed it with my fingers.
