Fan/pump is spinning CW (from top view); V-belt goes into the pulley correctly, controls correctly connected. Controls are turning the shaft on the swashplate/pump. Thin washer to the case and the thick washer makes piston contact. Operates absolutely perfectly, but exact opposite direction.

How in the world?!?! lol

Called Jeremy at Hydro Gear waiting for all call back. Thought I would hit you guys up as well.

Thanks for any help.

To help us narrow it down it would help if we had the actual model number from the tag. ZT2200 covers about 50 different models. And what center section did you order by part number. I am suspecting wrong center sections and it is plumbed for the opposite direction. Normally this happens when the output motor swath plate is reversed. but it appears this has a fixed swath plate.

Thanks for the reply! Here is information from the sticker on the right drive motor: ZC-AMBB-4DDB-3RPX (9341B10465)

Customer support sent a schematic indicating part number 71530 (part #57 for the RH. So I ordered this: https://www.amazon.com/dp/B0FFZ39D58

Will a LH center section bolt perfectly onto a RH motor? If so, maybe they mispackaged at the plant? Box does have 75130 on a sticker, but it does happen I guess.

I suspect the parts schematic was interpreted wrong or the wrong part was boxed by the vendor. Amazon is just the point of sales distributor.

Definitely a difference in the center where the fluid passages are located. Right is the replacement part-left original..
