Oil drain Screw Socket

[Kwt-B4]

Hi everyone ..

what the right tools to open this engine oil drain and where to buy it?
I look every where but i cant find it here in my country , maybe because this Military engine never sold here in Kuwait.


it's 1950's M37 230 engine.

see the picture for more details .

Thanks in advance.

On this same topic:

Does anybody know what tool is supposed to be used to get the tiny drain plug out of the pumpkin of a WM300? Its smaller then 1/4" drive ratchet...

It's not a square headed plug?

3/8 " or 1/4" ratchet wrench. Also not sure where to get them I have a set of socket drive looking wrenches in different sizes has clutch tools on the box. They came in a box of tools I got from my wife's father.

This may be a project for the "special tools division"! If it is an inverted square drive, you could start with a 3/8" x 1/4" drive adapter and carefully grind the 1/4" square drive until it fits the plug. Be sure to quench it often as you grind or you will loose the temper.

It is also possible, and may be desirable, to drill out the plug and re-tap the hole. This would be a good option if you intend to fully disassemble the axle. You could open the hole up to accept a larger, faster draining plug size.

This is actually what I ended up doing with a 1/4" drive...I'm still puzzled by this oddball size.

It was almost easier to drive a flat head screw driver into the whole diagonally, and attach a vise grip to turn it!

Getting those inverted drain screws out was one of the first jobs I ever did on my WM300. Ended up grinding 2 adjacent flats of a 1/4" extension shaft. I think it's about a 3/16" square now. I used it again the other day on the 6x6.

Dodge must have had a tool to do this instead of expecting us all to make them like we have...has anybody ever seen one?

in market u can find only screw sockets with 6 or 12 pins and dodge use 8 pins , and now for Audi modern cars they use 10 pins.
