I have a 1960 730 diesel. The tag on the pump says to drain and add crankcase oil, my manual is very vague when it comes to the pump. I did some diggin around and read several times that the cap on top of the pump is where u fill it and the plug towards the bottom is where u drain it. but when i look in the top or drain it all i get is some really nasty smelling diesel, NO OIl??? do I have a bad seal that is letting diesel into the governor housing? any info on this pump is greatly appreciated. Justin

Someone else reading this will probably give an answer, Is there a plug on the rear square cover, if so that may be the level plug. Anyway, you can of course put to much in but if that tube I told you about is open it will only allow the pump to retain the proper amount, the rest will drip out to the proper level.

The very earliest 730s and 830s were equipped with the pump that requires servicing. If your 830 has a fitting coming from the engine block to a fitting on the injection pump it does not require anything except regular servicing of the engine oil. My 830 and I suspect his 730 were the ones with the aircleaner mounted on the side of the tractor and had what we call the Lo profile tinwork, and eagle hitch. mEl

No you do not have a bad seal, just the results of the pump not being serviced. The plungers in the pump have a small amount of natural leakage and that is why the pump has liquid the consistency of fuel. Even with new fresh engine oil the dilution process will start over again as soon as the engine is run. If you will notice there is a small pipe that comes down to a bracket on the pan flange with a loop in it, that is a drip tube and allows diluted oil to leave the pump so it does not get overly full. Change the oil and refill it and then run it a bit and redo it to flush pump an extra time then when ever the oil is serviced in the engine should be sufficient. My 830 was the same as yours when I bought it and the oil still gets thin between changes, also I'm sure the plunger fit has somewhat worn over the years and caused dilution to be more than when the engines were new. Newer engines that lube the pump from the engine oil are still leaking just like ours but the fuel just goes into the engine oil and is not seen as ours is. mEl
