Hey Karin;

You do realize that there is an entire board on this site dedicated to just the ford N-series tractors, right? Good.

One of the more knowledgable but kinda grumpy types on the N-board constantly preaches "Clean, bright, and tight" on all electrical connections. This is especially important on 6V machines but is just a good for 12V machines as well. Rust and corrosion anywhere will limit how well the electricity flows on the tractor. Since you have the starter off, look at the metal on the flywheel housing that was covered up by the starter...is it rusty? if so, clean it up good with a wire brush. Do the same to the face of the starter when you get it back. This is where the starter grouds itself and it needs a good connection.

Another spot is the ground cable. Especially if it is a woven strap. They are prone to rust and get corroded and not work well. Check ALL electrical connections and make sure there isn't paint build up under them that is preventing good sparkie flow. If all that checks good and the starter still won't do right (and the battery is fully charged), then you may have bad brushes in the starter meaning rebuild time.

Also, if your tractor is still 6V, I found that jumping directly to the starter with modern battery cables wasn't always good enough. 12V batteries use smaller diameter cables and that is too small for 6V systems to get enough "juice" to run. I had my starter rebuilt only to find out that my battery cables were too small! Glad that you found out what your problem was, but please remember that there is a board here just for these tractors and we'd be more than happy to help you out with any problem you may run across. Good luck and enjoy your 8N!

What's the reason why the starter can not be removed? It's bolted on isn't it? Pull the starter and use a big screwdriver or pinch bar
to pry on the ring gear to see if the engine moves. If the engine can be rotated, your starter
or battery or both are the problem. Hal

You can check the starter by reconnecting the battery to the starter. You can short across the
solenoid with a screwdriver to see if the bendix
is energized and the the starter gear flies out
as if it was going to engage the ringgear.
Be very careful doing this and only touch the
terminals on the solenoid for a moment. Do not hold the screwdriver on there and have the gear spin without any load. Above all keep your hands,
fingers or loose clothing away from the starter
gear. You probably should take the starter to
an electric shop that does starters, generators and alternators and have it tested and cleaned. They have the equipment to load test it. The bearings could be worn too. Hal

Like some others have suggested. Check those battery cables and connections for any corrosion.
Heavy welding cable make good battery cables. You can solder on new spades with a torch. Glad the engine wasn't seized. Hal

How about some questions -

What do you mean by restored ? Cleaned up and painted or everything taken apart and rebuilt ?

Why do you think that the engine is seized ? If it was running a couple months ago and has not been run out of oil, it is unlikely that it has seized up so quickly.

If you put it in high gear and rock the rear tires, will the fan blade move ?

If it just slides the rear wheels when you pull it, maybe the rear end full of ice.

How do you know that the battery is not dead ? Sparks at the points does not mean that the battery will turn the starter.

Hook jumper cables directly to the starter.If it spins,that part is good.

Doesnt sound like a very good restoration if the plugs are loading up (rich carb mix/flooding) and the oil is full of water/moisture.I wonder if water got down the muffler and rusted the rings up?
Being partial to 300s,I would recommend supplementing the Ford with a 300/350U...you may find yourself using that one more than the N.

If the stater is locked up, put the tractor in 4th. gear and rock the tractor backward. This will unlock the starter.

Karin:
Could be that the starter is stuck/jammed on the flywheel which could cause the problems that you are having; I'd remove the starter and see about it.

Karin,

Sounds like the battery is dead, maybe?

That goo in the crackcase and the sooty plugs is telling you that the tractor is not getting warmed up enough to burn off the moisture and is loading itself up.

Make 'er work for a living and all that will stop. Promise.

Allan
