Stuck Motor

As if I didn't have enough problems, the motor is stuck on my Super C. We put on a 12 volt battery and it wouldn't budge. Tried again a couple minutes later and it spun the fan a 1/4 turn then stopped. Waited a few minutes and tried again, but it wouldn't turn over. We poured some oil down each cylinder and will try again.
 
Pull the starter off and look inside. I had one that did the same thing, and it was caused by an animal nest inside by the flywheel. All covers were in place so i'm not sure how they can get in but they do.

Hey thanks for that information. That didn't even occur to me. I'll do just that and report back.
 
careful forcing it, I have found the pushrods can bend on those, you may want to pull the rocker arm loose so they do not get bent

This is not the behavior of a truly "stuck" engine. Remove the starter then see if it will turn with the crank. If not, stick a pry bar through the starter hole and into a ring gear tooth on the flywheel. Try to move it a bit backwards (pry the visible part of the flywheel down). If it moves at all, start looking for whatever is causing the bind. If is doesn't move, you need to dig deeper for the problem.
 
Took starter off.

1. No rats nest, but did find a small dirt dauber nest. Cleaned it and made sure starter was working.

2. Tried prying flywheel, but it wouldn't move in either direction.

3. Not related, but I took off valve cover and it was nice and oily in there.

I assume I need to pull the head. I'm going into uncharted territory and will need your guidance.

I used to wrench on my old car back in the day, but it's been a real long time.

Looks like I need to remove the Carb, manifold, and water pump.

1. I assume the the rocker assembly above only has 2 bolts correct? When I remove those it will lift off. Is that correct?

2. Do the push rods need to be kept in order? If so, is there anything else that needs to be done. So I can get it back together?


Anyone here willing to be my mentor? You guide me and I'll post what's done with pictures.
 
you can leave the manifold and carb on the head unless you want to make it lighter, water pump is in the block, not the head, just has a bypass hose to connect them, keep the push rods in order is a good practice, they are adjustable also
 
My brother reminded me of something last night. He and I tried to pull start it in the summer of 2013 and it turned over, but we couldn't start it. It was in gear when we tried.

So I know it was not stuck at that time.
 
A frozen up water pump or fan could give the illusion an engine is stuck too (if the belt is good and tight). A hand crank might help you out in getting some leverage on the crankshaft to see whats going on. If you're not worried about the belt, cut it off and rule that out. Most need replacement anyways. Should one of the pushrods be bent, I have plenty used ones. Roll them on a piece of glass to check them out. Last time I checked, a new one from Case/IH was around $80 each, although aftermarket ones are available too.
 
Ok, been busy last two days. I move slow, so don't laugh. With all the encouragement you guys have been giving me, I decided to see what I could do.

I took off valve cover and removed rocker arm and push rods.

I tried once more by jacking up the right side and put it in 4th gear. Tried to move wheel, but the motor was still stuck. So I began spraying every nut and bolt I could see with WD 40 specialist.

I was really blessed. I got the the nuts off the head, I got the exhaust manifold off, loosened the thermostat housing from the head, and if I didn't miss anything, the head should be ready to come off.

I've got to be honest, I put this off for a year because I was afraid I would break a bolt. I knew if I did, I would probably never be able to fix it. I'm glad you guys encouraged me to dive in. Not one single nut gave me any trouble!

It was close to dark before I was able to get close to removing the head, so I stopped right there and put away my tools and all the parts I had removed. My wife labeled all the zip lock bags and put all the nuts in the bags.

Tomorrow is another day, but they say we have rain coming.


Oh I did find one odd thing. One of the nuts of the exhaust manifold was a different size. Someone put a 13 mm nut on. I kept scratching my head trying to figure out why my 9/16 wouldn't fit the thing!



Oh one more thing. I haven't been able to check them close, but the push rods don't "appear" to be bent. When I get time, I'll roll them across a piece of window pane to make sure they're straight.

One question, I was reading on here and I noticed that someone recommended replacing head bolts during a rebuild. Is that correct?

Yes. Especially since you probably don’t know how many times they’ve been on and off previously.
 
Here's one I tried to reuse, it was an original and stretched. Luckily it didn't break.

Got the head off. I have several pics. It's giving me a rough time trying to find an easy way to post. I'm not smart enough to get them all on one post.

Does anyone have any ideas from the pictures? Any help advice is much appreciated.
