I have a 2 ton 3 jaw puller to remove the harmonic balancer. Is this the correct one to do the job?

 

It should do the job....here is a link with install guide.

Great link. The number of my puller is 27011. Would it be better for me to get the 27139?

 

That I do not know. I dont know the differences between them.

 

Appreciate the help.

 

You need a 3-jaw puller. The preferable type is the "chrysler" style puller, which you can borrow for free from most auto parts stores.

You could also use a 3-jaw generic gear puller, though you will need to take action to protect the crank snout threads.

See this link for what the puller looks like: http://mach1tool.com/library/OTC-6284.jpg

I wouldn't go by part number. That number will vary from brand to brand, and there are lots of companies that make these, but they all use different numbers. Memorize what it looks like (or print out a picture) and go by looks.
