Hi, we have a U302 diesel, as a rule it starts right up. We use it to seed oats and pull a 12 foot drill. Last year after it was running about an hour or so it decided to just stop. Got it out of the way and let is sit for the day. Next morning it started right up. Thought problem was a typical issue we have been having with old Rosa Master pumps, so we pulled pump off and had local shop tear it apart, check over and replace the famous plastic parts that disintegrate. Problem solved we thought. Getting ready to plant this week, charged battery and it started right up. Again after an hour or so it acted like it was not getting enough fuel. Stopped in its tracks. Pulled it out of the way. I was seeding over at my place and about 4 my brother drives it over.
His thought is that there is a very small bit of air being pulled in through the primer which is right before the fuel filter. Has anyone had these primer pumps apart? I assume there is an orange or two inside. I dont think the primer can be bypassed as getting the fuel system bled would be a pain..
Any thoughts. Nice tractor and more than enough to pull the grain drill. I suppose I could always put a 12 volt pump on but wish to keep it as original as possible. Looks like Im going to need to keep it handy and rake hay once we determine whats happening.
