Now that I have close to 50 hrs. on the JD 5205 MFWD, I figured I best start looking at maintenance. Just a quick note: I am not the most mechanically inclined person. So here I go. First, I figure an easy thing to start with is draining the water out of the fuel water seperater. Easy enough; just unscrew the bottom fitting until the water drains and the fuel starts to come out. The manual tells me I am suppose to get a constant flow. I unscrew the fitting and only get a couple of ounces and the flow stops. so I unscrewed it all the way and took it off. I only get a couple of more drops, so I reconnect it and tighten it up. I figured that went pretty good, and I crank her over and and she runs for a couple of seconds and she dies. #$%@% !!!!! What the heck did I do? The first time I touch this machine ( except for changing the rear flat tire) and I kill it. However I remeber you guys talking about bleeding the fuel injection system if a diesel tractor ever ran out of gas. So I get out the manual again and follow the directions, tighten everything back up, turn the key and BAM, she fires right back up. She ran alittle rough for a few seconds and then idled real smooth. Thanks to this site and you guys, everything worked out for the best. I was able to get the machine running again and was able to get some gravel on the road leading back to the "good barn". Questions - Why did she lose her prime, how can I prevent this in the future and if it does occur, do I have to totally disconnect the return fuel line or just loosen it real good? Now I'm kinda hesitant to do anymore. I may just take it back to the dealer to have them do my break in service.
