1925 (similar to TC33) Vent in Front Axle?

[AlanB]

I thought there was a discussion on this in years past but cannot seem to find that discussion. Is there a vent on my front Axle? Front drive or assist or whatever.

When I open the fill plug dipstick in the left leg of the axle, you can hear the pressure venting out.

I operate in mud and muck quite a bit, so I suspect that if one is there, I have plugged it, but dang if I can find it.

RickB? Help

Am I looking for something that does not exist?

Most of the conversations I recall highlighted the need to be very careful when adding fluid to the front axle. The reason was there is no vent and room needs to be left for expansion.
I do not know of a vent on my 33D.
