Zetor 6245 fill plug

[Stratton6245]

I have a zetor 6245 and the fill plug for the front diff is missing. Tried finding a bolt to fit it but a 10mm is too big and an 8mm is too small. If someone can help me out that would be great! Or have a part number for the actual plug so I can order one. This is the fill plug not the drain plug

Maybe it's 9mm or 3/8" SAE.

it should be npt [ national pipe thread ], found at any hardware store pipe/plumbing.

The bolt is a M8. This is the plug to check the oil level. It is to small to be a fill hole.
The fill hole is left on the axle. The drain hole is on the bottom of the differential.

The M8 bolt sits in a plate, if it is stripped out, this should be easy to upgrade to a M10.
