flywheel nuts lock ring

[Deleted User]

When T took the flywheel of my crankshaft, I noticed that the five nuts that hold it on, had only some copper flat washers under them.



The join between the flywheel and crankshaft has to be sealed with proper sealant, and a gasket, to prevent auto trans fluid from leaking out, because the flywheel becomes part of the torus case when assembled, and I assume the copper washers were there to make some kind of seal between flywheel and nut.



However, other than torquing these nuts to the recommended 45 ft pounds, I saw no other way provided to insure these nuts never come loose inside the torus.



Somewhere, in some picture or diagram I stumbled over, that I can't seem to locate again, I think I saw a type of steel ring that slips over the studs, and has little tabs that you bend over against the nuts to keep them from backing out, sort of like the ones you use on wheel bearing nuts, to keep the wheels from flying off.



If this is a stock part, does anyone know where you could order these, or are they a make-it-yourself kind of part ?

I haven't seen anything like this from 37 thru 54

I just looked in the 1937 parts manual (you didn't mention what year yours is) but they only mention the nuts, not even the (non-lock) washers!

Thanks Bill, I'll be ordering three of these in the next day or two, if you can spare that many.



Also, if you have a couple of the little locator tubes that help you align the trans to the block, I'll need at least two of these as well.



Thanks,

The lockplate should be an easy manufacture for a local machinist. The flywheel can be used as the template for hole spacing and the size limits. The attached JPEG is an crude drawing of what you will need. An alternative is to drill the acorn nuts and safety wire with .020 steel wire. The alignment pins for the trans to the engine can be made by curtting the head off a proper size spare bolt. Good Luck
