It’s a magnet clamp plate that fell off the flywheel. It would be unusual if it didn’t do any damage. There would be the head of a brass screw inside your engine too. Unfortunately, it is now time to pull the engine, remove the hogshead, pan, and transmission. Replace the broken part and look for additional damage.

Just leaving it the way it is and continuing to drive it is risking Thousands of dollars in damage...

Time to pull your motor. That is a magnet clamp the brass screw lost its head.

Take this seriously, a magnet coming apart will do a LOT of damage.

When I was at at Lilleker’s a few weeks ago he showed me an engine he was pulling apart that had a magnet come loose. It looked like a small bomb had gone off inside the hogshead. I should’ve taken a photo of it.

Take this very seriously. You are very lucky to have discovered this when you did. Under load, a magnet coming loose inside the transmission could shatter the hogshead like a bomb and not only destroy your engine but the resulting shrapnel could possibly pose a danger to the cab interior and those occupying it.

Ok. I got to figure out how to get the flywheel notch at the correct spot to take the starter off. Take the hogs head off and check out the repairs needed.

Did you take the drive/bendix off ??

It’s a lot easier to disassemble with the engine out...and it HAS to come out.

find someone locally who is acquainted with this work and ask for help. My guess is that you have already damaged the mag ring, and you really need some boots on the ground helping you at this point.. The good news at this point is that the mag ring is old and very likely damaged from loose parts flying around and needs rebuilding anyway. It's always a good idea to replace with a rebuilt unit when undertaking the sort of repair that you're faced with. This is a very significant teardown that takes special tools and knowledge of what you're doing.

Best of luck.

While it is a big deal, it really is not that complicated for someone who is mechanically inclined. In 1970, when I was 16, I bought my ‘26 Model T coupe. It was before the internet and with only a copy of the T-1 Model T Service Manual (my copy was green, now a days, they are black), I completely rebuilt my model T, by myself. There is not a bolt or part I have not handled on my T. Until then, I had only worked on lawn mowers, so don’t be too cautious. The Model T is very easy to work on and very forgiving. If you run into a problem, just come on the forum, post a couple of pictures and ask. Chances are, you will come away with the answer you need. Jim Patrick

Re "the flywheel notch at the correct spot to take the starter off." The notch is in a fixed location on the coil ring, see note above about taking off bendix first.

Ok it didn't take me long to figure out the starter notch.. I got it apart, when I think back the first oil change I did when I bought the car was a year and a half ago and the brass head was in the oil drain plug.. That means it been hanging together at least that long..what I was going after is the low pedal notch. Got that all apart went pretty well, about 3 hours..Now this mag thing popped up.. What are the odds I put it back together and it runs another 20 years ??? I dont disagree it should be rebuilt but next thing you know I won't have my T for the summer... decisions, decisions decisions

Are you attempting to drill out the pin holding the low pedal notch ?

You might strongly consider the consequences of what IS going to happen if'n you don't repair the problem as most folks here are offering sound advice !!!

If it really is a difficult decision after seeing Dan and Ron's pictures, there really isn't anything else anyone can say which will help. The brass screws have crystalized, and more are waiting to fail. If this transmission lasts long enough to undergo a planned rebuild, you will find that other heads will invariably pop off during disassembly, and with remarkably little force.

Good luck.

All I have to say is consider what is pretty much directly above the transmission and magnets when you are driving the car. Having magnets fling off the flywheel at engine speed directly under your feet can cause severe injury to not only the car but also to you and your passenger. It's not worth running the car anymore until this is fixed.

Are you seriously delaying a rebuild to address an existing, dangerous and eminent problem because you want to drive it this summer??? Seriously! It would be wise to forego having it this summer and rebuild it so you will have it the next several summers. Either do it voluntarily and inexpensively to an intact engine, or do it involuntarily and expensively to a destroyed engine. It may be ready to explode the next time you run it. Jim Patrick

If the engine is running ok,and there were no major problems,you should be able to replace the mag coil, brass screws and plates and reset the gap and put the thing back together.Just because a magnet clamp came off does not mean it needs new piston rings and mains.it is a repair that can be done with time and not to much money. BUT to continue to run it would be like riding a A bomb around .

I agree with tdump. If the engine is in pretty good shape, then just a "freshing up" may be good enough depending on how you plan to drive the car. But the magnet plates and the brass screws. "MUST" be addressed and replaced. It sounds like you have made the decision to have it fixed. .It may seem like a really big deal. And to a certain extent it is a big deal and a pain in the @$$, and wallet. But pulling the engine and fixing the problem is the "ONLY" good decision there is. Any decision other than fixing the brass screws and plates could make for a very, very, bad day.
I would suggest to also check the valves at this time. If the engine still has the "cast head" two piece valves, they should also be replaced. The "cast head" valves have been know to come off and destroy the piston and sometimes the block. You may be lucky, and the valves are already the newer one piece style

Wishing you good luck, and have fun and be safe ..

Also... In the picture of your low speed notch, you had questioned how it could have worn that much on the inside with plenty of oil? The answer is that it probably hasn’t... The low pedal needs to travel maybe 2”-3” forward BEFORE it hits the ramp and begins to engage the low band. That first 2”-3” engages neutral. If you “repair” the cam and notch to have zero play, you will not have neutral at the pedal, only at the hand brake lever. Also, most of the repro low speed cams and notches have zero to very little pedal travel for neutral and require very careful repeated grinding & fitting to producers the proper amount of pedal travel before engaging low band.

Adam, you are absolutely correct in that there needs to be some play between the ramps on first gear. In my first attempt to rebuild the ramps on a RHD pedal, I eliminated that play, and had to re-introduce it! 2-3" seems a little excessive though. I would have thought 1.5" would be sufficient, bearing in mind that as things wear, the gap/pedal travel increases anyway.

I was not aware that new first gear ramps and notches did not give the required free play. On our RHD cars these are used on reverse and the brake pedals, where you don't want play anyway.

U-joint: yes, should slip out.
Valves: appear to be 2 piece, recommended changing.
Good news is it looks like all the cylinders were firing good.
I think if I was this far into it, I would at least look at the crankshaft bearings, but a minor refresh may be all that’s necessary, along with the flywheel of course.
You’re doing good so far ! :)

Old two piece valves have those two holes in the head to accommodate a tool used in lapping them in. However, many replacement one piece valves also had the two holes, and can be re-used if good. Look in the ports to see if the head is a separate piece to the stem.

I know you’ve already made the decision to tear it down, but just to bolster what Scott said above about the brass screws becoming unstable....

I elected to replace all the brass magnet screws on the engine I’m running in my T now even though none of them had lost a head. On a few of them, just the slightest amount of pressure caused the screw head to pop off. In other words, they were very weak and the likelihood that they would’ve come apart was not small. I use my mag every time I drive my car and do it with a higher degree of confidence than if I’d hadn’t.

That's too bad. Someone left you a "gift" with the band washer and who knows, but it may have taken one or more of the magnet keepers off for you.

Buy the manual and MTFCA booklet on the transmission or better yet, send it to someone with experience and a history of transmissions that have completed a number of tours faultlessly. There is a good deal of inspection and likely machine work ahead, not to mention one-off specialty tools and fixtures needed. For a single transmission job, you'll be far ahead of the game doing that rather than purchase everything you need and trying to farm out individual aspects of the job.

Why would the transmission and engine need to be completely overhauled just because of the brass screws? Take the 4 bolts loose holding the transmission,determine which brass screws as far as size were used,and put them back in all the way around and replace the transmission on the shaft and check clearance and when finished reassemble?

That would be one way to do it, if you didn't inspect for cracked magnets or replace 100 year old aluminum spools AND were young enough to lift the entire transmission/flywheel off of the crank a bunch of times while setting the mag ring/keeper gap AND the triple gear pins and bushings were in perfect shape.

Myself, I'd pull the drums for that work.

Pulling the drums, and setting mag ring and magnet height typically require specialized tools.

But you're right, replacing one keeper (or all keepers) doesn't require a total transmission or engine rebuild. Only inspection will reveal the extent of repairs that would be prudent. What is prudent to one person is rediculous overkill to another, and I understand that.

The only thing I know about this car is that it might have 2 piece valves, and it ran for a good while with several pieces of loose metal in the bottom of the transmission and that in itself requires careful investigation. But that's just me.
