my 354 just started leaking hyd oil in front of the seat around the block. it is leaking in atleast 3 different places. it is causing pump to hum and jump sometimes constantly some time every few secs. the lift stays up after turning tractor off. i have the picture marked in three places the top two places you can see ooze out when the pump jerks and the bottom not sure where it is leaking, just see it running out of the bottom corner. any ideas?

Hi Steven, has the hydraulic reservoir become pressurized? Either by the suction filter becoming clogged or some internal leak. Loosen the filler plug and see there is a pressure build up.

Hi Steven, there is also an orifice screen on the input behind the large plug on the lower right of the top bolt that you have marked in your photo.
Remove the screen and clean it.

i rebuilt the piston last year becuase the lift would leak down and everything has been working smooth untill i was bushhogging the other day and it started leaking. i took the orifice out but it was clean. i cleaned everything thing up real good and new hyd oil when i rebuilt piston last yr. reservoir is not building up pressure.
