After the Apple Fest I brought home a 71 JD 140 that pop wanted to part with. Drove it around a little but really did not pay attention to it. So into winter camp it went.
Was getting a little board so went up and dug it out yesterday. A few coughs and hacks and she came back to life. Did I mention she smokes? So with her loaded we came back home. Down to the man store for oil,points, air filter and such.
Started with a good bath ,removal of the deck(41) and for attitude a set of 24x12x12 on the back.
New tune up and oil and she still smokes. Guess I’ll need to break it of that habit. Don’t really want to tie up the garage doing a full resto but feel if I get started that’s what will happen.
Other than smoking she is really not in bad shape. Need to repair one of the head lights. She has a lighter that works believe it or not. The adjustable seat is a nice touch too.

Nice, doesn't look bad. I would like to find a 140.

Had the head off today a lot of oil laying
on top of the piston. Not good not sure if a ring is not lined up right or what but it does look like someone’s been in there.
There were hone marks just visible in the cylinder walls. No lip on the top so looks like I’ll have to get my brother to measure the bore for me.
That’ll be in a few weeks . A few other things going on until then.

Nice looking 140. How's it going with investigating the oiling problem? I recall reading Brian Miller's info on his pullingtractortips.com website that he didn't find that piston ring gaps being in alignment created much of a problem. He mentioned staggering the ring gaps on rings and the next time he disassembled the engine that the ring gaps had more closely aligned themselves but didn't seem to create an oiling problem. He attributed it to heat expansion & contraction along with normal vibration/running over a period of time. I'm wondering if a piston ring may have been inadvertently installed upside down with the chamfer/bevel in the wrong orientation? Hopefully not but if you do decide to do an engine tear down check the ring orientations carefully and see if they were installed right. Could possibly be the cause of oil pumping, not sure of course but it may possibly be the cause or possibly a broken ring. Good luck on it and keep up posted.
