JD 410
My 410 backhoe has a leak which seems to be coming from the plug located on the bottom of the pump. I have the Tech Manual and I took the plug out, replaced the O-rings but it still leaks. The machine starts and runs great. Is this an indication of a another problem and what do I need to do to stop the leaking? Any help is appreciated.

I went to the JD dealership so I assumed they were the right ones. Thanks for the specs. I'll go back to JD and get another set. The hoe is at my acreage 50 miles away so I'm not going to get to it till this weekend. I'll let you know how it turns out.

Got new O-rings and replaced them. Leaking has stopped.

Thanks
