Can the flywheel be removed from transmission without dissasembly of trans?

No, everything builds on the flywheel.

Thanks for quick reply and answer to my wishful thinking question. I am dong a refresh of my engine and going to replace magnets with dist. ignition. Don't want to mess with trans, as car did drive ok before this engine work. I hope I am not being short sighted in leaving trans as is. I appreciate you help. Don

You can remove as a unit & replace/remove the magnets without tearing down the transmission.

If the engine is coming out a distributor is not a good fix for a non-working (assumed) magneto . Fix it right while it's apart.

If you remove the magnets you'll have to install a paddle kit to move the oil around.
The magnets in a model T serve double duty, create electricity and move oil.
If you remove the magnets you'll need something to replace them with to move oil .

Also it would be a good idea to balance the flywheel once you remove the magnets as it will throw balance of the engine off.
Which it's always a good idea to balance any engine.

Agree with all the balance work possible on a T. In this case, where poster doesnt want to tear down the transmission, extra balance work isnt required. Ford balanced the flywheels before the magnets were installed. They are close. Oil slingers of some sort are a good idea. The ones from that southern central state had a reputation of coming apart. I dont recommend them.

Yes. You can just lift the transmission off the flywheel. If you plan on putting it back together make note of which triple gear goes where so they are not mixed up. You do not need slingers. Just install new spools and they will stir up the oil sufficiently to lubricate the engine.

The transmission will not just lift off the flywheel. The output plate must be removed to get to the clutch hub. Hub needs to be pulled & woodruff key removed. Then drum pack can be removed.
It would be interesting to see how much oil spools only move comparatively. No personal experience here. Oil needs to be slung around to saturate the transmission & get oil into the internal funnel to the motor front. Part of the field coil function directs oil into the internal funnel.

Are you saying that ford balanced the flywheel with the magnets on it? If so how did they drill the holes behind the magnets?

I've run my speedster since '94 with spools but no magnets or mag ring and never suffered a lack of oil to the transmission or timing gear. Plenty flying around to take care of things. I did add an external oil line to help feed the mains and rods until I switched to an A crank and added a pump to move oil to the mains. Try replacing the band cover plate on the transmission with one made of clear plastic. Lot's of oil gets moved.

Yes, I have seen what happens with a clear cover. I would like to see how much oil moves comparatively to a spooled only flywheel. The lesser oil friction from slingers would be an advantage. Some use only the ring gear. Before I consider it, I need hard, substantial proof.

So are there any videos of oil slinging with just the flywheel or spools?

I would disassemble the transmission. After the transmission is removed from the flywheel, it only requires the driven gear be removed to complete the disassembly This does take a substantial puller.

When I rebuilt my engine, I thought about not disassembling, the transmission but glad I did take it apart.. The reverse drum was cracked. And, I replaced the worn bushings.

The transmission shaft goes through from the front (magnet side) of the flywheel. How in the cornbread he!!— that’s when one gets a bit of cornbread stuck in their wind pipe and start’s coughing— can you remove the transmission from the flywheel without disassembling the transmission?

As I mentioned previously, The drive plate 6 bolts must be removed, the center clutch hub pulled, woodruff key removed, Then the center shaft can be slid out & drum pack loose to be lifted off with the trpple gears.

You are correct. The transmission must be disassembled to remove it from the fly wheel. The center shaft locks it all together.
There must have been some editing. Wasnt the original question about removing the magnets without disassembling the transmission?

There is two steps to disassemble the transmission. First remove the transmission from the flywheel as mentioned above. This requires a puller. Next, to complete the transmission disassembly, the driven gear must be removed by using another puller. I don't understand the confusion

Your procedure is correct to remove the transmission from the flywheel. This involves partial transmission disassembly. I am recommending that the transmission be totally disassembled in order to inspect the drums and bushings.

I would agree. You got it torn down that far, go all the way & do a full inspection. Check drums for cracks & bushing wear.

Thank you all for responding to my question on flywheel very hlepful!
