L2550 First Start Question

Im not sure about the start up question in reference to the oil but you might want to consider draining the first few ounces or so from the bottom of the fuel tank (watch the color/debris/algae), if you havent done so yet and be prepared to change the fuel filter in the near future. Best of luck.

You'll need to prime that fuel system. Do you have a manual for the tractor?

If your tractor is 4 wheel drive (L2550-DT) you should also check your front axle oil. You may have already done this.
I'm not sure about what you could do to get the crankcase oil where it needs to be before starting. Filling with the fresh oil should have gotten some oil in the guides.
The main reason that I am posting is to let you know that these tractors have a pretty good clatter from the diesel igniting. It sounds like sharp knocking. I bought mine used with about 1200 hours on it and was a little concerned about the sound. After watching (and listening) to several YouTube videos, I determined that this is normal for diesel tractors of this vintage. I have over 100 hours on it with no problems in very hot or below freezing weather.
I did need to put new seals on the front axle - it is common for the originals to leak. It had no oil, but the gears were not worn.
As shootem604 said, bleeding the injector pump is a must to get the fuel flowing.
Good luck and let us know how things work out.

There is probably a decompression knob on it that would prevent it from starting. Then spin engine in short bursts using the starter to get oil distribution or spin engine by hand.
