Farmall 656 Hydro

Ok, I can't figure out whats going on with this tractor so I'm turning to the internet.

I have a Farmall 656 Hydro. I've had it maybe 8 years, put around 8-900 hours a year on it. I've put 3 or 4 flex plates in it in that time. It keeps breaking the "spider" arms. My serial # ends in 44091. So the book calls for the "spider" flex plate and not the round one with springs. However on the flex plate there's a sticker that says "flywheel side". If I install it that way, the hub of the flex plate hits the charge pump before the tractor "comes together" where it is split. So I have been installing them backwards, but then the splines on the flex plate don't engage the charge pump shaft all the way.

I don't understand what is going on. My flywheel is stamped 396468 R2 L2, I think it's right. Are there different configurations of charge pumps? Is the flywheel wrong? What else could be going on?

BTW it has a D282 motor. Also the wear on the flywheel bolts is from after the flex plate broke.

I think the sticker is just on the wrong side. The spring loaded disc won't fit original flywheel. No different charge pumps. Been a long time since I repaired one of those hydrostatic drives but I doubt any would engage the hub any more than yours appears to. BUT, with that wear on the shaft, it will never last more than a few hours. I would contact a hydrostatic repair facility like in Glenwood , Minn and they would give you the answers. Other places I know but don't know where they are. We had a couple that alignment was a problem from new and they didn't last long. After second failure on one that had shaft replace also, we went to the different flywheel and spring loaded center, no problem, still running.
