On the bottom of both chain cases front and rear is a pipe plug. If it is in good condition it will take a 5/16" hex to remove it. The conditions the machines operate in around where I am located are not easy on the machines, they are usually worn down to nothing and require drilling and removal with an EZ out, in which you will need to come up with new plugs. Check for cracks on top of the chain case usually in the top front of the machine, or where the cab bolts to the frame behind the fenders. What model do you have? They all hold about 2 - 2 1/2 gallons of oil in each chain case. Some of the LX885's had a separate dipstick for the gearboxes. The dipstick is located inside the cab right behind where your calf of your legs is sitting in the machine. If equipped with this you can use engine oil, hydraulic or gear oil in the chain case whichever your prefer. If the machine does not have these dipsticks you will need to use 80W90 gear oil because it is common with the gearbox. It may be worth your while to drain the gearbox as well. Contaminated oil can lead to parking brake and bearing failures in the gearbox.

What machine is it? If it is like the lx665 the reduction gearing is seperate from the chain case. chain case is 10-30, reduction is 80-90.

Sorry for the wrong information, I was headed to chain case when you said milky oil. Usually the bell housing oil under the seat doesn't get contaminated, it either fills up w/ Hydraulic oil from leaking pump seals, or leaks out due to bad pump o rings. There is a square headed drain plug under the pumps. You will have to drop the belly pan to access it from underneath the machine. The bell housing holds 1.5 QT of 80W90 EP Gear oil. Check to make sure the breather on top of the fill plug is not broken or missing. That is about the only way contamination can get into the oil.

The book on mine says nothing about draining that gearcase just filling it. In order to see it you would have to take the cover off between the the front and rear axles but I see no drain listed for mine?

I got thinking again after the last post. The gearboxes are common with the chain case on a LS190. If you pull the side cover there will be a little funnel that catches oil dripping off of the chain that runs oil into the gearboxes, and level with that is another hole where it will drain back into the chain case. The chain case and gear box on a LS190 require a 80W90 Gear oil. On both gearboxes there will be a drain plug accessible from the bottom of the machine after removing the belly pan. They don't hold much oil on their own, but around 3 gallons total gearbox and chain case combined. If the gearbox is contaminated then the chain case is as well.
