I posted about this a while back, but I have a John Deere 400 which uses the Sundstrand 15 inline. The transmission and hydraulics seemed weak and I narrowed it down to the charge pump. I was finally able to get the drive shaft off and the charge pump removed. It does not look bad overall, but it is definitely worn toward the outside of the outer ring. Ive heard these are still available. Where is a good source for a new charge pump or parts. Also someone mentioned having a good used one available. I would be interested in that. This picture shows the wear near the outside edge.
Thanks for your time,
