Is the crank puller built into the crank?

How does a self extracting mower crank work?
Self-extracting systems use threaded rings that look similar to a crank dust cap. However, these crank retaining rings are threaded over the crank bolt, so that when the crank bolt is loosened the shoulder of the bolt presses back against the ring, which in turn slowly pushes the arm from the spindle. No additional crank removal tools are required.

When does the crank pulley on an R53 fail?
The crank pulley on an R53 takes power from the crank and supplies it to the serpentine belt, in turn feeding the alternator, AC compressor and Supercharger/water pump. It is a rubber-filled damper and this part is known to fail on the R53 around 80-100k miles (or 72k miles in my case).
How does a tensioner work on a crank pulley?
There are 2 pins on the tensioner tool that slide into the side of this cover. The cup at the bend of the tensioner tool sits on a large bolt and uses it as a pivot point. Fit the tool onto these points and pull down on the handle of the tool slowly to get an idea of how it works. It slips off very easily, so be careful and take your time.
