I am in the process of swaping in a JDM D15B inot my 92 CX. I am currenlty tearing down the engine to replace the gaskets, timing belt etc... I have run into a snag, I can't get the Drive Pully Bolt off. I searched the threads, which led me to buying the SJ tool kit for removing the bolt. Even with that, I can't budge the thing. Currently I am using a breaker bar, with a 4ft extension on it. (I don't have an Impact gun, or an air compressor large enough to drive one) Also, the current Drive pully has 3 grooved sections (1 for ALT, 1 for AC & 1 for PS). I am not installing AC or PS as the car is not equiped for either. Question is: Can I use the Drive pully from my USDM D15B8 instead. It only has 2 grooved sections, which will make it a little bit lighter? I don't want to go with an aftermarket Drive Pully as I understand there may be harmonic balancing issues. Any suggestions are greatly apreciated.
