Yes i believe these are all parts specific to the HST, I will post a parts list, a few of the parts i just "fixed", I welded up the worn pin and reinstalled, I also had a hole worn in the neutral arm assembly that I welded up.
Cams was not to bad, I did have that portion of the transmission completely separate from either end of the tractor so it was a little challenging to remove the front cam bolt since everything was moving around
Not bad at all just real time consuming but the cost savings is worth it, parts were about 1300 with all of the worn out stuff I discovered
This is the farthest I have tore into this tractor, I have also repaired a blown head gasket and I have broke the front pinion twice and repaired it twice!
My only question now is do I replace the PTO cam clutches while the tractor is split? according to the serial numbers i already have the updated clutches.
