front axle 4720h oil

[herm0016]

I can not seem to find how to check the level of the oil in the front axle of my 4720h. I see the fill plug on the right side hub, but no stick or level check bolt??

my hubs leak a little bit and i want to make sure I keep it topped off. also, it says 80/90 on the fill plug, but the manual says to use trans/hydraulic oil.... any recommendations there? the manual covers about 10 different models so I am inclined to go with what's printed on the fill cap.

thanks.

One side is the vent and the other side is the dip stick/fill port. I can't remember exactly which side is what but I believe the left side is the dip stick.

ok, i did not know if that yellow steel bolt was meant to be removed or held / adjusted the lash on the left side. the right side has an obvious plastic fill cap. stick with the 80/90?

Yes the yellow plug is the dip stick on the left side. Just confirmed with mine. 80W90 should be just fine. That's what came on mine from factory and that is what I'll keep using when the time comes to change it.

On my 2400H fill - dipstick is on the left and fill only on the right.

I would use what ever type of oil is in there now. Typically gear oil has a distinctive Oder vs hydraulic oil.

mine was filled with 80-90 gear oil from the factory, no clue on yours though.

You can fill from the dipstick side too. I was having problems with oil leaking out the fill/vent when operating or parked on a side slope so I replaced the vent on the right with a swivel and hose to a reservoir. Now I use the dipstick side to fill.

Some people have had problems with seals on the front axle, and some have had problems with the bearings. When the bearings get play in them the seals wear and leak.

it smells like 80/90 yes. but bought used, so no idea of someone changed it. ill stick with that.

Eric, I remember you describing this before. Do you have pics of how you plumbed it? I'd like to do something similar because we're also in hilly parts.

I need to take some pics and then I'll write up something.

Don't go out of your way Eric but much appreciated.
