Changed out the fuel filter per TC40 owner's manual #86620668 10/00.
Tractor won't start after multiple cranks.
Went to bleeding air from the fuel system at the filter-still nothing.
Then went to further bleed the fuel system, page 3-8 and 3-9-open the fuel shutoff valve.
Open the bleed screw, 1. at the pump, until air-free fuel flows, then close the bleed screen (sp-screw)possibly painted red.
My op manual is vague as to where the bleed screw is and what size is it-MM or SAE? Something hex head painted red or one or all of the four injectors?

Did you crack one of the injector lines open and crank it over......

May work for you but I seldom bleed an engine after changing a fuel filter. Of course I fill them full (as possible) before replacing them. I prefer to change them after have the engine warm. But with a helper I will shoot short burst of WD-40 into the air intake as the engine is being cranked at a fast idle. If you pay attention and engine is at fast throttle you can tell it is running out of fuel hit a blast of WD-40. Have a friend who says he uses a rag wet with gas and those fumes will work. Never tried that. I do remove the outside air filter but not the inner one. If you do this right you will not crank the starter much more than regular start.

Try blowing some air in the tank. Put the tank under slight pressure for a minute and it should self bleed.

Hi there - did you solve it?
On mine there's a bleeder screw to the right and down from the air filter and slightly above and to the right of the fuel filter. Here's what the TC25's looks like. My TC45 looks similar.

I just changed my fuel filter and bled mine there - it was (IIRC) an 11mm that fit it. Could be different on yours. I opened that and it bubbled a bit and then flowed without bubbles. I did that again after starting it for a minute or so. Shut it off and bled it again and a few more bubbles. I suspect someone with a lot more experience than I have will know more on this but it worked for me.

Hope that is helpful,
Matt

No I didn't.
In this photo, which is the bleed screw? Yellow or white arrow or neither? If it's the white arrow, it looks difficult to get a wrench on it. Any special tools needed? Maybe a universal socket? What size socket do I need? I can't get any of my sockets on it-I have limited mm sockets and plenty of sae sockets but nothing seems to fit. If it is the yellow arrow it takes an 11/16" open end wrench which I have.

Is the fuel filter full of fuel now? If not, remove that and fill with fuel and reassemble. Then try to start. I've never had to bleed the lines when changing filters, but I always top off the bowl before I put it back together.

I would crack the white one and try it...

If you have the fuel filter full and loosen one injector line on the injector and crank it over if should force the air out and start..

Here's another piece of the puzzle-I had a non New Holland dealer add a back hoe to it and for convenience I had them change the oil and fuel filter that I'm now replacing. Took out the fuel filter and there was no spring on the bottom of the filter! I've done this before and always made sure the spring was in place. Unknown to me the dealer left it out or lost it but it ran well without but I'm sure that condition didn't help the fuel filtration system. I have one on order. Part# SBA360740120

The spring keeps the filter on the stem so it wont fall down... you get it running yet ?

Does it matter where I crack the line, at the fuel pump or at the injector? I have four of each, any one in line better than the other? The ejector pump would be easier to crack, see my previous posted photo. The fuel bowl spring will be here in two days, hard to believe that it ran at all without it The hex head bleed screw takes a 10mm socket but a socket and handle together won't work (too tight of a fit against the engine block) so I'm searching the stores for a flexible open/closed ratchet wrench. Is there a better tool setup to open that bleed screw?

Any line at the injector...

Yesterday I picked up my missing fuel bowel spring and a set of metric open end wrenches and went about the air bleeding process. Didn't take too long, the TC-40 is back to running smooth as always.
Thanks all.

There's an interesting feature on that bleed screw. I ordered a spare because it looked like the hex head was slightly buggered up, turned out it wasn't. After finishing the bleeding process and putting tools away I looked closer at the new spare bleed screw. It has a small hole drilled up through the center of the shaft and then out the side for air/fuel to escape without having to completely remove the screw.
As you can tell, my limited knowledge and skills are nowhere near even a novice a diesel mechanic!
