I did search this forum, but I couldn't find anything about how to install back the crank shaft pulley. It was really hard to took off, and I would appreciate some addvise. (Can I heat it up a little to slide easier on the shaft?) Thanks.

 

I use a threaded rod as a stud and then pull the crank pulley into position with a nut. I also use a bearing between the nut and the pulley to reduce friction. A couple of large washers will also work.
