Don't know when the electric pump was added. I have a note that the mechanical pump was bad. Mech. pump appears good when I had it out. Problem with pump is that the hand primer had the round hand piece missing so I think it wasn't screwed in not allowing the pump to work. I took a cabinet knob, cut down the knobs shaft, drilled the center out just a bit smaller than the shaft and pressed it on. Pump works as it should now.

You might have to remove one or both bolts holding the alternator to get the belt on. Compare the old with the new. It may still be the wrong belt for your tractor. Just because the book calls for a certain one does not mean it will fit. Things could have been change by the previous owner or changes when made. If it is too tight do not use it. Go to NAPA or auto parts and get a longer belt that fits. I have a TYM that I had a problem matching belts, had to go to a longer belt. Good luck.

Is #1 in first pic #21 in mine?
Is #2 #27 in mine?

#21 is for draft control, you will want it pushed to the left most of the time, right when plowing

#22 forward the brake is on, would not use it there unless the pto really needs to come to a sudden stop. mostly use center to disengage and rear to engage.

#23 should be turned clockwise to independent pto, engine drives pto. you do not want it in the counter-clockwise ground driven position. no real use for that unless maybe use use a old sickle mower.

the pto should not be strong enough to turn the mower when disengaged

all my tractors have a different set up then this one, maybe someone else will chime in.

you second picture may be of the draft control. could you take it from further back? it is in the rear?

I would also recommend cleaning the whole machine with a pressure washer. I do this to any new to me machine, helps to find leaks and other problems

I have put the electronic ignitions in a 504 and a cub with no problems. I tried two different brands and a third on the way. Both are the same except for the price. I have purchased them from both Ebay and Amazon. You might need to know which distributor you have. They say not to use copper wires and replace them with graphite. They also say to use a newer coil but your old one is just fine. If you have dust shield you will have to remove that, just save it if you convert back.

Have you got an update on the stuck engine? If you removed the rod caps and where able to move the pistons then that eliminates them. have the clutch engaged and then try to bar the flywheel, that will rule out anything after the engine. If it is still stuck then the problem would be in the front of the engine, gears there drive the cam, fuel pump and counter shaft. Let us know what you find!

Here are some manuals for the tractor. The wire diagrams are not the best but the manuals should help with other problems.

I have a 1100 and can't seem to keep water out of the hydraulics. Is there a case vent for the transmission or rear axle housing? I can't seem to find one. Thanks for any help.

I would replace any rubber line that you have on the fuel system. With the newer diesel the rubber lines are swelling, I have had problems in several tractors with this.
Did you also clean out the primary filter and wash the screen?
The system is self bleeding but can suck air into itself too. I had a problem with the primary filter drawing in air after I had cleaned it once. Since it draws the fuel from the top of the tank in later models it is easier to draw in air if not tight.
After I replace filters I prime the system with the line feeding the injection pump loose till fuel comes out. Close this and continue pumping the primer, when the air is out you can hear fuel returning to the tank.

If it had run until air got to the injector lines then you will need to bleed them as well. Prime the system, loosen the lines at the injectors. Crank the engine over, with the De-compressor lever pulled out. Close the lines when fuel sprays out.

You can charge each battery separate without pulling any cables. There are some chargers that have a 24 volt setting but I would still prefer to charge each separate.

Hi and welcome to the forum. Is this tractor new to you? do you have any manuals for it? If you unfamiliar with this tractor it could be several things. first you will want to make sure it is ether in high or low range. second you will want to have it ether in forward or reverse. ether of these could cause it not to move even though you have it in gear. if after you are sure of this and it still does not move, engage the differential lock and see if it moves. if to only moves in lock then you could have a broken axle, if it still does not move then it could be with the clutch.

here are manuals for a 250as, same with the exception of 4 wheel drive.

I can't recall if it will flow on its own there. If you have a rubber hose between the tank and pump then you can pinch it off. Spray the shut off at the tank with penetrating fluid and you should be able to work it slowly loose. Its always good to have this working.

Welcome. Look over at belarustractorclub on yahoo. There is a file section there that should have most of what you are looking for. I have a 250AS, I use 105w40 in the engine. For the hydraulics they call for motor oil but since I hook up attachments to the tractor I use hydraulic fluid so I don't cross contaminate, works fine and no problems yet.
