Allis Chalmers 5' Rotary Mower Gear Box Oil?

Will Herring · Nov 10, 2012

I am going to check the oil in my gear box tomorrow, and wondered what weight oil it takes. I assume it is 90 wt gear oil? The plug is right there above the old "AC" logo.

Also, can anybody tell me what model this is, so I can try to find a manual for it? It's a recent acquire, and I don't know much about it.

You have the model 160-T 5' trailer mower. I have a model 172-M 6' 3point mounted mower. My manual covers both models. It says the gear box takes 3 1/2 pints of SAE 140.

You can always use Jd or case ih. cornhead grease. This lube
is almost like gear oil, but much better lube material.

SAE 140? Wow. Would not have expected that.

I assume you just fill it to the top of that fill port on the side of the gear box housing?

Also, thank you for the implement ID. Didn't look quite like the other 160s I have seen -- it seems much bigger from front to back than the others.

It's a pull type AC 160, those wheels can be flipped 180 degrees,
and moved inboard, if you don't want to leave tracks. I use 90W140
in mine, no problem. There is also a grease fitting, below the gear
box, in the back, to lube the 2 lower bearings.

Will, There are two plugs; the one on the right
side is the fill plug, the one on the left side is
the level plug. Left one is lower; fill right plug
til it starts to run out the left plug. Very good
mower. Made for AC by Brillion (I think).

Whew, good to know! Will definitely be doing this tomorrow.

Oops, I forgot to ask if I needed to grease anything else. Also good to know; will hit that with a few squeezes of grease as well.

The early 60" mowers were made by danuser, not brillion. This one is a laporte built model.

Put a quart of 85w140 in (as it was all I could find around here)... Found it took the first pint without pushing anything out the level plug on the other side. Finally she started to let some "goop" out. I'm glad I topped her off... I kept adding it until what was coming out the level plug looked halfway decent. Mower ran good afterwards, too.
