Been slowly rebuilding an RPS34 in an early 970. Have come across another question I would appreciate some advice on. Please understand I am a worry wart, and this mighht be a silly question. Hopefully it is.
From looking at the diagrams, manuals, etc, on the EARLY powershift, there really is nothing supporting the C1 reaction sun gear except the 3 planet gears with which it engages. The later ones look to be supported internally by the input shaft. With that said, mine is the EARLY version. I have the refreshed unit all bolted in to the torque tube, and it just seems like the C1 sun gear is looser than you would think is acceptable...almost hanging down a bit by the weight of the disks. See red marks on photo.
Does the rotation of the C1 sungear, and the action of the planet gears on the sun gear cause it to self center itself? It just seems like it will wobble around, possibly wearing the disks, plates and teeth funny?
The planetary seemed fine when i had it out. The gear teeth all had little if any wear evident, and the bearings seemed to be tight as well. Same with the C1 sun. Do I need to revisit something inside, or is this normal and rotation will hold it center between the planets?
I did search the archives and find 1 thread with discussion about the same issue between 2 gentlemen, but the question was never really resolved.
Thanks very much as always for any advice.
