Mark:

If you are beefy and used to lifting large weights at odd angles, you can get the head off yourself. If you are NOT used to lifting large chunks of steel, bales of hay, etc, get a helper. I'ts a long reach, and back spasms will definitely make the job take longer.

The bolt pin can be pulled using a bolt and a pile of washers or a socket -- you don't need a slide hammer.

Wire the chain to the cam sproket, then use some stiff wire (brazing rod or flat silver solder sticks are what we use) to slide under the head and through the chain when you get the head loose. It is somewhat important that the chain stay tight on the lower part. You will need to wire it up and hold it taut while exchanging the heads, another reason for having a helper.

Check your chain stretch before you start -- a new chain, if necessary, isn't that big a deal to put in.
