What is the proper puller to use to remove the gear on the generator? This is on my '26.

This is the correct tool that I use, Bob

Also, do rebuilt generators have a better cutout system? I keep reading about overcharging issues.

Scott the generator is a “system” and the cutout is a “system”, the model T generator does not have a integral cutout built into it. It’s an add on in the form of a mechanical or electrical encapsulated device.

Sorry...But the Model T, for as simple as it is, it is not a low maintenance vehicle. When you get your generator operating again, follow the instructions for the setting of current, if you you use a mechanical cut out, adjust the system as recommended in the literature.

Check the car every time you start it up - oil, charging, coolant, tyres, etc.

And recheck the vehicle every 500 miles.

The as designed systems work, remember too that in modern vehicles there are micro chips monitoring the systems...with a Model T, you are the engine/vehicle management system.

I've often been intrigued by the comparison. Old cars require more work, more frequently, but it's easier, sometimes cheaper and you can do it at home by yourself. New cars require less work, less frequently, but it's harder, more expensive and you can't usually do it at home by yourself. (At least with me)

Unless you have an aftermarket voltage regulator, the generator is set to charge by adjusting the third brush at the top. loosen the nut and slide toward the engine to increase the charge and move away from the block to lessen the charge. If you drive often, long distances during the daylight hours you can set it for around 4 amps charge. If you drive mostly with the lights on, adjust it to just read about zero with the lights on. If you drive infrequently for short distances, you can set it for 5-10 amps. If you think you might be overcharging turn the lights on.
Anyway, you get the point. How you adjust it depends on how easy it starts with the starter and how often you drive and under what conditions you drive.

I hesitate to ask, have you solved the charging problems you were having in the thread you started in June?? Did you purchase another generator for your car?

No. For a bit there I decided to sell it, but realizing that I'd have to take a big loss on the car I pulled the ad. It was on Facebook. I would still sell it, though, even though I do like the car. I have tested the generator and magneto with common tools that I have at hand just as the Ford mechanics would have done back then and found that both are dead. The magneto will have to wait. The generator seemed simple enough and it probably is once I get the gear off. Birdhaven in Colfax is less than and hour from me and open tomorrow. We'll see. I did reverse the wires on the back of the ammeter and it shows a discharge when it's appropriate for it to do so. It appears to be backwards of what it should be, though, but it works.

Mag is easier fix that generator. Just takes a couple 12 volt batteries and a compass. If the coil is good and most are.
Generator will most likely need an armature.

Be sure to pull the pin out of the gear before pulling it.

If the generator is allowed to over produce, (cutout failure typically) It will sling solder from the commutator. There is obvious solder spit under the end cap. The commutator can be re-soldered. Typically the solder connection breaks before total destruction & the armature is savable.

The most common failure is from the 3rd brush insulator being over tightened, & broke, allowing the brush holder to contact ground.

Also possible & the easiest to fix is gummy, oily brushes or brushes worn down to far. Spray some brake cleaner & give it a good visual whall still on the motor.

Would most any puller work?

Would most any puller work?

Only if they have the clearance for the legs to fit between the housing and the gear.
