Oliver 2255 fuel filter/fuel line routing

rhomium · May 19, 2020

Hello all. I have cruised this forum many times over the years. Now I actually have a project to ask for help on. I have purchased an Oliver 2255 to use/restore. Now that I have it home, need to get it running. It's one of those "ran when parked" tractors. Looking at the engine today, the fuel hose routing seems a bit farmerized. The center tank isn't even hooked up. I'm hoping some of you that have a 2255 can take a few pics of the engine from each side, front and back so I can see how wires/hoses/fuel should be routed and hooked up. Attached is a pic of the rear of my engine to show what I am looking for.

Thanks for the help and I'm sure there are many more questions to come.

I see the picture didn't upload. Let's see if it works this time.

I'll see if I can get you some pictures of mine tomorrow.

You?re right, your fuel system has been cannibalized, the black iron fittings are the first clue. The added fuel filter and duel solenoids are next. I am thinking that the reason the main tank was disconnected is somebody installed a vented cap which would make a real mess if the fender tanks are full and sometimes the engine will stall with this setup.

Hopefully J.Wondergem can get you a good photo, if not I will shoot a couple for you.

The service manual has a good fuel circuit diagram.

Here's some photos. Sides are still on and har to get pictures without a back flash. hope these hel, if not let me know, I'll get some more.

Ok, thanks for taking the pics. I'll print these photos off and go see if I can sort things out in the next few days. So how well does the original system work? Or would it be better to run a vented cap on the main and fender tanks, but have them plumbed separate to a fuel solenoid an switch tanks when say the main tank runs low?

And I have a shop manual on order.

And here is a pic of the entire tractor. It's all complete. The side panels had been laying underneath the tractor. I need to remember to look at the serial # and find the year. Trying to get it running by end of summer for some fall tillage. As I go, I'm sure I'll have a lot more questions for you guys.

I have about the same as yours as far as tanks. I just use the main tank as I don't use it that much. I have a 1850 that has fender tanks, and that always worked with all three tanks the way they were designed to. Never tried a solenoid switch on a tractor, but used one on my semi tractor with a tank mounted cross wise behind the cab. That worked good.

Is that a 3150 or 3208 Cat engine. My dad had a 2255 with a 3150 Cat engine and had trouble starting it every time till we replaced the electric fuel shutoff gizmo on the injection pump. I had a 4-150 for a while and never had that problem , different pump on it..
On the 3150 we had to loosen the cap on the original filter housing with the switch turned on we could hear the solenoid click, then it would start.

It's a 3208. 1975 w/ 6800 hrs. Funny you mention the fuel solenoid. Got it running last weekend. Put in fresh batteries and topped off all the fluids. I thought I would be smart and disconnected the fuel solenoid so we could make sure it was going to turn over and get things moving without it starting. Damn thing fired up instantly. So I'm running around trying to shut off thinking is the water pump going to pump, is the blocked cracked anywhere, all sorts of things running through my head while this thing is running on its own. Finally thought to take out the fuel solenoid and shut it off by hand. Cleaned up the sticky solenoid and now it works fine. Took a bit of a tour and everything seems to work. Shifts smooth and purrs right along. I was rather surprised after it has been sitting in a field for 25+ years.

That tractor does not at all look like it has been sitting for 25 years. It's in unbelievable condition if it really has been sitting that long, and I'm a monkey's uncle.

If it was mine first thing I would do is drop the pan and check the rods and mains. The 4-150 (1974) I mentioned was a 3208 with just under 1,000 hrs when I traded for it, at a little over1100 hours the 2 back connecting rods opened the block up on both sides, only salvaged the valve covers and intake manifold, everything else was toast. Thinking back I think the bill was about $7500 with CAT furnishing 1/2 of the bill, or so they said. The tractor was 6 years old when it blew up only turning 12-1500 rpms going a rough gravel road.

It's possible you are correct. I have no idea of knowing for sure. The previous owners thought it had been there that long. The father had passed away a few years ago and they were cleaning up the farm. No one was exactly positive on how long it had been sitting.
