Case 224 dif oil?

breimer · May 16, 2013

Changing the oil in the differential (that's what I call it) may also be called a transmission or trans-axle. I need to know what kind of oil goes in it. To be clear, I dont mean the hydraulic oil which drives the tractor. Its the gearcase right under the gas tank under the seat. I'm thinking its probably 80/90 gear oil. The oil that came out of it is too milky and smelly to identify properly what kinda oil it is.

Also I have a tiller attachment for it and I'd like to service it properly as well. The cast iron case going down to the tines, what goes in there. It appears maybe theres grease in it. Should there be grease? gear oil? Does it need to be changed? This thing is pretty old. I only found a plug near the top from the side.

You can use 80/90 hypoid type gear oil if you wish but you can
also use 15W40, 20W50 or straight 30W in the trans-axle. It's
up to you.

It's a good idea to flush the old milky oil out of there by pouring
in a quart of diesel fuel and driving the tractor around for ten
minutes or so and then draining the rear end once more. Then
put in a quart of any motor oil, drive the tractor for another 10
minutes and drain that out. Refill with 3 quarts of your choice of
oil.

The Tiller chain case gets packed with regular chassis grease.
Only you can decide whether to change it or not. You must
dismantle the entire tiller to do this. New seals on the output
shaft would be needed and so would a new #50 chain. Check
the top and bottom sprockets for wear and tear. This is more of
a winter-time project. These tillers do last a long time and
breakdowns are rare.

Just be sure you take lots of photos of how the tines are bolted
on BEFORE you dismantle everything.
