[QUOTE="krabill, post: 131730, member: 23026"] A new to me 853 I got knowing it had a "BAD" leak but the old owner didnt know where. I got it all cleaned up and found the leak. Its where the hydrostatic pump left and right sides mate, at the bottom. The leak is very strong when running. attached are pics showing the inspection mirror and you can almost see a drop of fluid coming out. It looks like there is a gasket between the two sides that failed which is causing the leak. I expect I have to pull the engine/pump assembly to do the repair which is fine and I think I am setup to do so. I have the service manual for the 853 but in the section for the hydrostatic pump it says " "SEE THE COMPONENT REPAIR MANUAL FOR HYDROSTATIC PUMPS FOR DISASSEMBLY AND ASSEMBLY PROCEDURE." I have searched all over for that manual online and came up empty. Does anyone have that manual in PDF? How hard is it to split that pump in half? Any tips for dealing with a leak between here? Rest of the machine seem solid otherwise. It still runs great and moves fine with the leak, but leaks a gallon an hour I was told. [/QUOTE]
