Hey CCJersey,
I replaced a leaking seal in the governor and in the process must have cleaned it up a bit. After that I found that the throttle will open only so far until I cranked the engine and the oil pressure goes up. I crank a bit until the pressure goes up and then stop to pre-heat for a minute. This way when I'm cranking and want to try to send more fuel I can.
I assume that one can pump up the fuel first with the hand pump you use when pumping after changing the fuel filter for example?
So the question is: where is the relief valve located? It sound like it's on the pump somewhere if I go to look for the return line back to the tank. I'll do some looking and once I find it it will be obvious in the parts book.🙄
Thanks for the input! Say Hi to each Jersey cow for me. Our Neighbors milk ~120 Holsteins twice a day and they all have names..
I never associated it with the oil pressure building up, but I know what you mean about the governor not allowing you to open the throttle until it is spinning. The D333 acts like that. From the parts book it looks as though the governor is a mechanical (fly weights and springs) type with only oil lubrication, but I may be missing something about the oil pressure. It does make the engine have to spin more before it'll crank when the governor won't open up the throttle right at first.
Pumping up the fuel with the hand pump before cranking it will help if it's leaking back into the tank and loosing prime. The check/relief valve on the return line should be near the filter and hand pump and the return line should be attached to a fitting in the center of a large hex head plug screwed into the fuel pump housing/filter base etc. Take the line loose, and screw out the large plug and the valve spring and plunger should be behind it.
I expect any air leak in the filter, pumps or lines will allow fuel to drain back if the tank level is lower than the engine. The generator set has a base tank under the engine, so it could be bad, but the D333 was the problem until I fixed the pump seals.
I try, but it's a little hard to keep track of all the cows w/o them being a number that's connected to a computer record. Only a few ever become familiar as an individual. Frequently it's because of some problem they had that required a lot of care for a while, or that one of the children showed them in the 4H dairy show at some point.
I think it's a good sign when the cows are willing to tolerate/investigate/greet the people moving among them. It slows things down when too many want their back scratched instead of moveing along to the barn, but there's a few that demand their share of attention every day.
Unfortunately when you are showing the herd to VIP visitors you would like to impress, the old, one eyed, cripple with only 3 teats that your daughter showed 6 years ago will be the one that comes up to them for some attention. 😄
