Checking gear oil in a Belarus 420AN?

[novaman68]

I am getting my Belarus serviced and ready to work. I pulled the plug on the bottom of the gear box that drives the front drive line (1st pic). This is the lowest point and the only drain plug I found. I have a few questions. Thanks in advance

1. Am I correct to assume that the transmission & rear end share the same oil?

2. There are 2 plugs (2nd pic)...are these the check plugs for the gear case oil level? If they are, from what I've read there are several configurations of the 400 series, would I use the front plug (higher plug in pic) on a 2wd and the rear plug (lower in pic) for 4wd (my model)

3. There is a large (1 1/4" or so) pipe plug on the floor board to the left of the shifter...I'm assuming this the fill plug for the trans/rear axle...correct?

I bought 5 gallons of 80w90, hopefully this is enough. Thanks again!

Anybody? Surely somebody out there knows something.

I have a Belarus 400 2WD and I use the top plug to check the differential oil. The plastic plug on the floor board is how you fill transmission/differential.

I have a 400AN and the two plugs for checking are what you have shown in the pictures. The top is the level your oil should be at or below if you have a gear reducer in your tractor, and the lower plug is where your oil should be if you do not have a gear reducer. I have a plug at the bottom of the gear case that I drain from.
