Default Removing the Flywheel

My 40 convert flywheel does not want to come off. Any hints? I also need to replace the pilot bearing. Any help wood be appreciated.

If you've removed the four bolts, it is simply stuck. Large hammer with a block of wood... tap a little on one side, then 180° from that.

I am not that familiar with what you are working on but is there any chance you could remove the bearing and replace it while leaving the flywheel on the crank? A lot of people remove pilot bearings by packing them with grease and driving a shaft in to force the bearing out with pressure from the grease.

The pilot bearing is integral of the flywheel. I prefer a shielded bearing vs. a bronze bushing.
It's a simple R&R without any special pullers, etc.

If all you want to do is replace pilot bearing, you can borrow a puller from autozone ,easy.

I am refacing the flywheel and I am using a block of wood at 9 and 3 and it moves about a 16th or so back and forth but it doesn’t want to let go. The pan is not off.

You MUST remove the pan. You will not be able to get the flywheel assembly out of the opening without the pan being removed.

1/16" at a time is about right.

Now go remove the pan...

I just discovered that it will not come out of the hole. Now that is a poor piece of engineering by Ford. I had to put the clutch assembly back on the flywheel and used a couple of pry bars and off it came. Then I discovered the new problem. So, I have the engine laying on a 1" square piece of tubesteel across the wishbones and now I have to take the pan off? Where do you secure the rear of the engine? Can I secure it from the floor to the rear of the exhaust manifold on both sides? There must be a way. I have always resurfaced the flywheel whenever I have done a clutch replacement. Did Ford think you didn't have to do that? Is the flywheel made of some super steel that doesn't heat up and crack? I am attaching a picture of the flywheel as it sits right now. If Ford thought it was unnecessary to resurface the flywheel, then I'll just bolt it back up. Other than having the half the clutch stuck to it . . . I made this transmission rebuild into a real job!

Your flywheel most certainly needs to be resurfaced.
Removing the engine in your car is approximately a two to three hour task at most. This was hardly a huge burden upon the owner "back in the day".
As you already have the transmission removed, I'd suggest you simply yank the engine out. In the long run, you'll most likely be glad you did.
While it's out, you may want to clean it up and repair anything that may likely show up.

Good time to clean the pan and the oil pickup screen at the very least

You are probably right. The engine needs detailing and paint. I won’t be driving until the trans go in. Does it make sense to put the engine and trans together and put them in as a unit? I’m thinking that what I want to do.

Well, the engine is not out. Everything is ready to pull it out except the "new" bracket for my engine stand is being ordered from Stumpy's. I am not willing to take the chance on breaking the bellhousing on a perfectly good engine. My question is, do I remove the exhaust manifolds from the engine now or just at the header pipe to the manifold? I have the nuts removed from the header pipe.

For now, you can leave the manifolds on engine until you remove it from chassis. You can always set the engine down on an old tire if you just want to get it out and done with. Drain the oil while you have it hanging on the chain. When you do go to remove the manifolds, don't be surprised to find the two FRONT bolts or studs on EACH manifold will be larger in diameter than the center and rear exhaust outlets. DD

Important: As V8Coopman noted, the two front exhaust manifold bolts are 7/16 NC, while the center and rear bolts are 3/8 NC.

It is quite easy to NOT notice and them mount the engine on the Stumpy's adapter with the WRONG bolts in the front - a very dangerous situation. So make sure you have 7/16 NC - Grade 5 or better for the front two and 3/8 NC - Grade 5 or better for the rear two mounting bolts.

You guys are a wealth of knowledge! It's like listening to my grandpa all over again. He'd be 123 YO! My grandpa never owned any vehicle but a Ford and used to work in the Ford Garage in Clarksville, TN in the 20's and 30's. I remember him "aligning" his tractors with . . . "that stick over yonder, boy, bring it here". I have a tractor wrench/gas gauge of his sitting on my desk. Looks like it held 8 gallons, Ford number 9N17014. Thanks.
