Get a thread file. They are made with 4 different threads on each end, for a total of 8 choices. I think it takes two files to cover the thread range, plus a metric file or two. It will save a lot of threads. Other methods cut away too much metal.
Try Sears, tool trucks, Harbor Freight, or a good hardware store. They used to be $8-$10.

If its just the first thread I'd use a dremel to just grind it out (flat). Your cap thread will just float over it and engage what's left.

Using a thread gauge determine the pitch of the thread off of the cap. Thread files are available at your local tool store. You will be a be able to repair the tread using the file end with the correct pitch. Or using a center tool and an old file grind the pitch angle and scrape the tread back into shape. I have done this many times before with success. A tap will not do you any good unless you remove the PTO drive shaft. A big job just to repair the cap thread.

You said the thread in the housing? Not the cap? Well that makes it a little more difficult! You can't very well use a gigantic tap as I assume the PTO shaft, etc. is in the way. This is what I would try. Assuming there is room to do it, using a Dremel tool with a very thin grinding stone, I would try to reshape that first thread by eye. I would be using my very best eyeglasses as I don't see as well as I did when I was a kid. Before I started, I would tape everything off real well so I didn't get and grindstone particles or grindings in the bearing or near the seal. Will it work? Can't say for sure, but I've done similar repairs to large external threads. Once I get the threads started correctly, I "work it" for awhile before I unscrew it completely. Has worked for me.

Randy; Get a die and clean up the first several threads. It will take a good size one, but you may borrow one from a local machine shop, show them the "CAP" so you get the right size!!!
