I was wondering if someone had an idea before I went tearing into a used 328 I purchased which was leaking... Its leaking hydraulic fluid near the center of the carriage on the ground between the two tracks. Someone mentioned to me awhile back regarding a specific hose or something which rubs and leaks but I can't recall what that was. I wish I had a exploded view of the hydraulic system and how to access it best...wonder if anyone has a scan of it they've uploaded. How do you go about getting access to the center area...is it best to do it from removing the plates from the top or...It appears that there is an access plate from the bottom...I wonder if it is the swivel joint? I guess my main problem is knowing which way to acess the parts...it could be any one fitting or hose that is leaking. I was kind of hoping to hear someone say look here...this is a real common problem etc. The unit has about 1400 hours on it. Thanks in advanced!
