WTB w108 flywheel!!!

[rae20108]

Hey there everyone,

I have a 1966 250s with an automatic and I was wondering if anyone here happened to have a flywheel sitting around they would like to part with. My starter gear has seemed to strip the teeth out of mine and I can no longer start the car....

Any help would be greatly appreciated!!!
and thanks in advance.

Are you sure it's the ring gear that's bad? Take the starter off and check the 'Bendix' drive. It may need to be replaced.

Check the ring gear itself. I've seen the actual "ring" separate from the flywheel and spin with the starter without turning the flywheel.

This is fixable on the car without disassembly or at least it is on a manual. Not sure about an auto.

Pull the inspection cover on the front of the bell housing and have someone engage the starter to verify. You can do it by yourself by marking a line on the ring gear and then attempting to start the car. After you crank the starter re-inspect to see if the lines still match.

Hello,

The 250S had two different crankshaft configurations with two different flywheels for the automatics. I probably have one laying around here but I would need the casting number off your old one to make sure it is correct. ja17@att.net.

I had already taken off the starter and confirmed the gear was stripped there are pretty much no teeth in portions of it and there are metal shavings laying in there.

Also ja17 that would be amazing, I will post the numbers as soon as I get around to removing it.

Thank you so much.

Oh and this is the picture i took of it a few days ago.

Hello,

I was looking at some of my flywheels yesterday. I do believe these ring gears are removable. They can be driven off. They are and interference fit. To install another ring gear, put the flywheel in your freezer overnight then before installation heat up your ring gear in your kitchen oven to 350 degrees. Drop the hot ring gear on the cold flywheel. It will slide right on. After temperatures normalize it will be secure!

New or good used is recomended but in case of emergency you can use the old ring gear over. If your gear is not worn too bad flip it over so the good non-worn side is out. The teeth on the back side are not beveled so bevel the teeth with your die grinder and install! However, from looking at your photo, it looks like your gear is scrap.

One other thing to think about. The original starter on your car is 0.8 HP later W l08 cars used a starter with 1.2 HP and it bolts right up to the earlier engines like yours, quite a bit more cranking power!

Just in case you don't have the industrial sized freezer Joe must have, you can use an oxy-acet torch to heat the ring gear for installation.

Lay the ring gear on the flywheel and evenly run the flame around the ring until it drops into place. Lightly tap it with a hammer to be sure it is seated. You want to keep the flame moving and not remain in one area very long to prevent removing the hardening from the gear. Do not force the gear using the hammer. You use the hammer to hear the consistent "ring" which signifies the ring is in place. Heat the ring until you get an even "ring" sound all around the circumferance.

The flywheel needs to be removed from the car and sitting on a flat surface for this procedure.

Hello,

Yes a torch works fine also. However your kitchen oven and freezer will do the job if you do not have the torch.

And as an added bonus, the ring gear is just the right size to cook a large pizza on while you are waiting!
