I have a late 80's yale that has a mazda FE79 motor. I read that there is a special tool to remove the the crankshaft pulley for the timing belt. the seal behind it is leaking. I have the parts diagram and it shows a tapered locking sleeve that it used to hold the pulley on. On the open end of that sleeve there are a few threads that this special tool threads into to then be pulled out. I need to purchase or borrow this tool, but cannot find one. Any help would be much appreciated.

Also, I have puller sets. this is not a job for any typical puller.
