It may also make a difference as to whether or not you want to install a new dampner. Kind of tough on the thrust bearing if you have to beat the dampner on with a sledgehammer instead of buying or borrowing a tool(Autozone has loners) that threads into the crank hole specifically designed for the job(in case you didn't know).
Or you can put the damper in the oven at 200 degrees for a half hour and pack the crank snout with ice for a half hour. The damper will slide right on. Remember to handle the damper with oven mitts.
