Wondering if someone could give some input on these issues I am having. I have a '93 M/F 1035 that always needs to preheat. Even in the summer it will not start until I preheat even after I has ran earlier that day. The second is the manual says to change the injection pump w/30 weight oil. when I pull the cover there was no oil in it. I filled w/8 oz. checked it later and the oil was gone again. So am I looking at a oil leak within the pump or does it go a magical place it the tractor and I can just forget about it and the pump will last forever??

I don't have an answer for you but I have found that it is rarely a good idea to use the stick your head in the sand approach to something that could cause a major breakdown in a piece of equipment. If you do not get any satisfaction on TBN contact your dealer.

On some mechanical injector pump the oil in the pump is shared by the crankcase but in most cases it is independent of the crankcase. There is a fill point on top of the injector pump, there is a drain hole in the bottom and there is a level hole in the middle to show where to stop. verify what type of the pump system you, oil should not evaporate or leave your system, too much oil can also cause same amount of problems as not having enough. You may take a look at the thread below.

Thanks for the info JC, my pump is a little different than the Fords it has a small cover to remove. I normally don't "stick my head in the sand" but I also know that you can cause more grief by being too curious sometimes. (I tore apart every thing when I was a kid just to see how it worked, and of course it never worked after that) but I work on junk on a daily basis and sometimes I wish I would just left well enough alone. I just bought the tractor last summer and have known it for several years. I know the last guy didn't mess with it. So, I'm figuring if it does need oil that it has been operating for a long time without it and may run forever if it is picking up oil from somewhere else. So its a decision to tear it apart now or just wait till it croaks, either way the damage has probably been done and it will cost $$$$$.

Skip,
I did not figure that your pump is identical to mine but at any rate idea is the same. You have a gear system off of the timing gear, crankshaft or idler in the timing gear/chain cover. That gear in turn will turn a camshaft and the lobes of the camshaft reciprocate several pistons that pump the fuel to injectors. there is also a governor in there that regulate the pumping action. There is just a little bit of oil(few ounces) in there and it does not get very dirty due to lack of combustion. Now I would neither just let it croak nor abandon it. take a few closeup pictures and post them, I'm sure the guys will be able to see what is going on. Will be glad to look at them closely.

I agree with JC..
Skip.. determine what type of pump you have, and if it has it's own oil sump, shares and oil sump, or is fuel lubricated.
if it has it's own sump and it drains.. that is NOT good.

Hi Skip,
"the manual says to change the injection pump w/30 weight oil."
If that is the correct manual, it sounds like you have a separate oil system for your injector, and it should stay filled until you drain it. Can you see any external leakage? If it were my tractor, I would fill the pump, let it sit overnight or longer and check it again. If the oil is gone and not on the ground, it almost has to be in the crankcase. Keep an eye out for an overfilled crankcase if you've filled the pump a few times already. Might just be shaft seal gone, but don't keep running it if it doesn't hold oil. It may be damaged already, but it will only get worse if you keep running it dry.
As to your first issue, is this an indirect injection engine? Most of those are supposed to have a shot of glowplug before every start.
Best of luck.
