Hex Head Plugs

[Tinwoodsman]

The drain and fill plugs in my 3053 tranny have 9/16" hex plugs. Why is that? My transfer case has plugs with 1/2" square openings.

Hex openings accept Allen wrenches and have pretty tight tolerances. The square holes accept ratchet wrenches and with them, there's a tendency to pull off-center and wallow out the hole.

The Spicer tranny in my 71 M35A2 also has 9/16" hex plugs. However, the Rockwell transfer case in this same Deuce has 9/16" spare plugs, not 1/2". Bought a hex bit set from Harbor Freight today. Part # 93203, $12.99. Still looking for a 9/16" Pipe Plug Socket for the transfer case.

You can order a hex "socket" for 1/2 drive from any autoparts store and that along with a few other necessities are all required for Deuce maintanence. I borrowed one for the first time I checked my transmission and then went out and bought one so I would not need to do that the next time. Other things that you should have would include the 8 sided 3 inch socket for your wheel bearing nuts on your spindles, a good gear type torque multiplier for your lug nuts and inners and a 8 ton jack with blocking and a jack stand for working on your truck safely. I am sure the list is way longer and to be honest I know I have left more than a few things out but I am sure you get my drift here.

I will take a hex head over the 1/2" square any day of the week. Those square plugs wallow out easily.

In a pinch you can also make a tool with 3 nuts, a bolt, and a little love from a wire feed (not required).

Yep, just get any 3/8" bolt and weld a nut on it. Or put a pair of nuts on it to jamb against each other. Then stick the head of the bolt in the plug and put a wrench on the nut to remove.

I just used a 3/8 bolt last week. It worked great, just make sure to use Grade 8 hardware. The cheap bolt and nuts that I started with just twisted right apart.
