Hey Guys: I'm looking for some help on replacing a hydraulic charge pump cover on my Fastrack SD with Hydro Gear ZT 2800 transaxles. My mower developed a bad leak on the right side which I traced to the charge pump cover. Talking to a parts distributor, I learned that the design has been changed from when I bought mine back in 2009 due to a lot of leaks on the original design. Got the new part today and it's one of those that will bolt on two different ways (one 180 degrees opposite from the other). The part didn't come with instructions so I'm hoping that someone who's done this before can tell me how to tell which way the new cover goes on using some kind of reference mark on the new part. Thanks for any help you can provide.
