07 SG tranny rebuild
My 07 Street Glide with 45,000 miles on it has transmission bearings that are shot and need to be replaced.
Here is a little background info, a few months ago I was getting the SG ready for a long trip, I noticed a whirling noise coming from the primary side so I took it to the dealership and they figured it was most likely the main shaft bearing, turned out it was a whole lot worse ,the transmission needs to be rebuilt, at a minimum the bearings and seals need replaced. If it turns out the gears are damaged I will most likely go with a Baker DD7 set up.
I ended up buying a 09 Ultra for the trip and now I would like to get ready to do transmission rebuild on the 07 SG on. I have never rebuilt a transmission before but do have the manual (I will even read it) I have tools but no specialty tools, I have a mechanical background performing pump and valve motor operator maintenance in the nuclear power industry so I feel I am capable of rebuilding the transmission. Hope so anyhow.
There are a few Questions I would like to ask:
What specialty tools will I absolutely NEED to do the job?
If gear replacement is not needed what would be the best seal and bearing rebuild kit to use? Since the stock Harley parts seem to be crap I would rather not go that route.
Any advise or tips on how to make this project go smoothly would be much appreciated

Like I said, if anyone one has some tips or advise it would be appreciated, I would rather not waste money on tools that are not needed.
Thanks

I was just reading a guys website that put in a Baker DD6 in a DIY project and it looked pretty straightforward. He made a special tool to remove the nut behind the clutch pack and a few other neat little tricks he talked about. Lemme see if I can find the link.

Thanks. Were you seeing any "fuzzies" or metal shaivings on the magnet on the drain plug?

The last few fluid changes the gear oil was a graphite looking color with as you say "fuzzies" built up on the magnet, no metal shavings per say.

A couple of specialty tools you will need is the puller to take off the spacer located behind the primary on the mainshaft. You will also need the specialty set so that you can remove/install fifth gear out of the main bearing and to remove/install the main bearing.
Sure sounds like a good time to convert to that 6 speed.
