I just picked up a 1816 Case to fix up a little. It is not a B or a C. It still has the original Tecumseh right now. Not running currently so keep that in mind.... As I go through the machine a bit at a time I have found a curious thing. The wells that contain the drive chains and gears are full of watery muck!! The machine has a full belly pan with NO access or drain holes. There are no holes between the drive wells and the pump/valve area in the chassis. How are these supposed to drain or stay dry? I am thinking of cutting some small holes on the bottom to drain them now and in the future. Water in and water out. Am I crazy or shouldn't there be a way to either keep water/debris out or drain these areas? On a side note, all Case parts manuals can be seen at www.casece.com , click Search for Parts, then click Launch Parts Catalog Looking forward to any responses to my first post here!!

can't say I have ever worked on one of these, but the chains usually run in a tanks of oil, not dry, or in water and mud for that matter. How are the bearings and chains? Very rusty I'm thinking.

Being new to owning a skidsteer I wasn't sure what was up. As it turns out, I am going to pull both axles on the left side tonight. It seems the sprockets have play on the axles and that shouldn't be since they have keyways.... Maybe the keys are sheared or shattered. Worse case I may be able to clean it all up and mill new slots on the other side of the axle. Hard to say until I get them out. The right side is nice and tight but I want to be positive. You are right, the left side is running in water and the right side has no lube. As far as my plans, I am taking out all four axles, changing the bearings and seals, and cleaning the chainboxes out. I am looking for an operators or service manual to assist in what to do with them once I get everything cleaned up and replaced. I definitely only want to do this ONCE!!

hogman I'm not too sure just how similar the 1816 is to my 1818, but mine has allen-headed drain plugs that are recessed a bit and hard to find. They are on the bottom, near the back, as I recall. My oil was a bit milky, but wasn't as bad as I expected.

Found that the chain wells are not designed to hold oil for lubrication. They are designed to be flushed with water periodically to remove debris and the chains and sprockets are to be oiled and maintained regularly. Got all of this from the service manual I finally found on eBay. On another note, pulled all axles, milled new keyways, cut longer keys and tapped sprockets for set screws to hold them as well. Got all new bearing races, bearings and seals as well as new 60 chains. Really a pretty easy job since I have all the tools in the shop... Once everything was set to specs, a very tight machine in the axle and sprocket area. Now on to getting her started. Already put the motor back together with good compression and new seals. Spark is there as well as AC current to the rectifier. Once it runs I am expecting to find hydraulic leaks.... Hopefully will have it up and running by the weekend.

Good to hear you are making progress. Even better when you have the tools in the shop to do all the reapirs your self.
