800 planter

[Country ave]

I have an six row 800 planter that I have used for a few years and generally like it, however, when I shut off the pto the 1000 rpm pump shoots out oil out of the fill cap hole and makes a big mess. If I under fill it I do not get enough pressure. It helps a little to idle the engine before shutting down. I have been putting IH no. 1 30 wt. oil in it as that is what I have on the shelf. This year has been the worst. Anybody else have this problem? Any solutions?

Did you make sure the cooler under the left side of the seed hopper is clean. Might be running too hot. 30 weight oil is what is called for.

the pump oil needs to be 30wt non detergent to avoid foaming.

Thanks for your input, I looked for a cooler underneath the shroud could not see one. I assumed the cooler was behind the louvers on the left side and hit the slots with a powerwasher. Went out to plant and it was still blowing oil then the cap came off the pump and dumped most of my oil. Got a new cap refilled with oil and only could blow 5 or 6 ounces versus the 12 I could get before. Tried a spare pump and could only get 4 or five. I do not think that is enough pressure to plant right. Need input, I could finish tomorrow before it rains if I get some help.

Then is no. 1 detergent oil?

Yes No.1 oil 30w is the thing. Guess I want to know where the diverter valve is set? Expect that you're seeing 4-6 lbs on guage when drums are full? And you've checked for the obvious leaks at seam and lid and at firewall of drum? Yes, I've seen cooler plugged enough that they get hot. It's under the loovers---find it and clean it. If you don't know by now where it's at it tells me it may be pretty dirty.

Yes, I am embarrassed did not know about the cooler. However the oil would still squirt out even after a couple minutes of run time. Drum had corn, lid seal and drum seal were tight, saw no other obvious leaks. By the diverter valve, I assume that is the one on the pump, it is screwed tight. What is the best way to clean the cooler? What is the minimum pressure I need for proper planting? I believe the book said 9 to 13. I could change the pump filter, not sure it would help. Like I said lost pressure after pump cap fell off and vibrated the oil out. I was running 9 to 13 before the cap fell off. Spare pump was worse.

Just guessing, does the fan turn free? Maybe a bearing locking up on the fan. Change filter if you haven't lately.

I gotta wonder whats goin on in that pump. vibrated all the oil out? change the filter for giggles and try it, could be causing an anomoly. check the cooler please!!!!! remove the blower motor ( its splined) and try to turn the fan--should turn fairly easily after you get it moving. If the fan turned real hard you'd suffer seal loss though.

I went this morning to the salvage yard and picked up a 540 pump. No more spray. I think that I had to much vibration in my 1000 pump. However I could not get over 6 ounces of pressure with any of the three pumps I tried. The oil cooler is definitely clean. Could find no air leaks. I am beginning to wonder if I fried my orbit motor when I ran out of oil. With rain on the way I am going to remove the fan assembly and check it out. I planted the last 15 acres of corn on six ounces of pressure. Hope it turns out all right. Either plant today with low pressure or wait a week or longer for the rain to end. Is there any way to test an orbit motor other than to keep trying pumps?

 

[gcnehring]

the motor has no option but to turn. If it doesn't turn it will blow the seal so I doubt that the motor is the problem. Think you're right on the pump if you ran for quite a while with no oil. Consider that the pressure guage may very well be inaccurate.

 

[Country ave]

Can the motor turn but not up to speed, if it is worn?

 

[gcnehring]

no
