I have a D2350 and purchased a hydralic pump through Valley Power Equipment. The were less expensive pumps available through another dealer but I had called Bill Rogers at Valley so many times for advice, I decided to stick with them. When I had a starter problem, Bill suggested I start with a local starter shop who rebuilt the starter without problem. Bill does not always try to sell something so I felt that extra for the pump and less for the starter worked out OK. In case you need it the phone number for Valley is 800-609-5110. Lots of good info on their website at Valley Power. Please let me know if and where you get rebuild kit for the engine in case it need to find one.
