I'm in the middle of a timebelt/waterpump/cam seal/water hose replacement job on my Miata. Everything is going well except for the crank pulley. I have damage to the pulley surface that contacts the drive belts and I am replacing the pulley. The new to me part is supposed to be delivered by Friday, or Monday. Apparently you can find 1.6 pulleys all day, but 1.8 are as rare as hens teeth. I opted for an OBX underdrive pulley, so we'll see how that works out. Anyone use one before?
Here is my issue and main question. I pulled the pulley with no issue, but everything appears fused together (lots of rust). I just want to make sure that there are indeed multiple parts to the crank pulley on the 1.8. Correct me if I am wrong, but there should be a spacer, then the pulley and then the inner portion that actually fits onto the crankshaft. Is that correct? I want to be sure before I use the BFH to "delicately" persuade the pieces apart. This would be after letting it soak in PB Blaster to help things progress.
