I rebuilt my 1979 T2X myself after watching three youtube videos and reading
several online articles. I was afraid, but it turned out that I shouldn't have
been. :)
The 3/8-inch bearings are available from amazon, ebay, and Hy-Gain (mine were
fine, but I didn't know that until I opened it up).
The user manual, which includes some useful rebuild info,is downloadable.
The plastic bearing retainers are available from Hy-Gain (mine were fine, so I
reused them).The mounting bolts were available from my local Fastenall.I used
Lubriplate Low-Temp grease, good to -40F, which outta handle MN winters, which
was available from a jobber down the street.I used DeOxit FaderLube and
Stabilant 22 to clean and rejuvinate the positioning pot (on hand). I also used
these to clean the control unit's pots and switches.My unit's ring gear is
missing half of one tooth, but it hasn't been an issue turning a lightweight
hexagonal beam. The ring gear is available from Hy-Gain and other service
outlets.
My T2X, purchased used, came with a new screw terminal plate (available from
Hy-Gain, but it turned out that my terminals cleaned up nicely. Replacing this
plate would have been the scariest task of the entire rebuild, had it been
necessary.
All replacement parts are available from Hy-Gain, the unfortunately named but
otherwise fantastic Norm's Rotor Service (does he work on helicopters I
wonder?), and elsewhere.
Most internal parts for all of the Ham-x series rotators are identical and can
usually be swapped around. These are essentially the same rotators, with the
T2X having a third set of bearings and a slightly different housing.
If you don't want to dig in yourself, I would use one of the aforementioned
independent rebuilders before I sent my rotator to MFJ. YMMV.
Best of luck,

I bought a rebuilt T2X from W7KD last year. It was in great shape. I
think he also does repairs. You might also check with N4TB.
