Flywheel inspection plug...

Flywheel inspection plug... as I was creeping under the truck I saw that the plug that I believe is the flywheel inspection plug is missing where can I obtain something like that...?

You may find it in the glove box. They are only used when fording and the T.O. says to keep it in the glove box when not in use.

I'm sure I'll find something in the glove box not sure it that'll be it... suppose its not there and I want to make make it so the vehicle can ford where would I go looking for one...?

Be careful though if buying a plug from a plumbing supply, etc, Most of those plugs you buy today are from offshore and although the plug may fit the threads, it may also be a loose fit, and able to thread in far enough to contact the flywheel. I almost made that mistake. I replaced the civy cover that was on mine with a military one and went to install a plug that I had lying in my drawer. I didn't know at the time to leave it off and it bottomed out on the flywheel. Glad I learned that lesson or alot of trouble could have ensued

Which could be why the original one in the photo has a lip on it. That would keep it from being run in too far and with a gasket, would provide a better seal.

Tapered pipe thread relies on the taper to ensure that when the fitting is properly torqued it will not loosen. Therefor it is very important that you tighten it to that specified torque and if too much extends into the housing you will have to remove it and grind some meet off the smaller end. Stopping short of correct torque on a pipe fitting will result in the fitting working loose. That original flanged tapered pipe fitting when tired and worn out will not thread far enough in to tighten up and will need to be replaced when that happens. Also tapered pipe fittings seal via the threads which is a good reason to use a pipe fitting sealant with them such as medium weight Tite Seal.
