A few years ago an old experienced mechanic brought his Jubilee to me with a leaking rear seal. The rear seal had been leaking so he replaced it but while he had it apart he threw in new main bearings for good measure. The rear seal still leaked after he put it together. After several attempts with both rope and neoprene seals he couldn t get the leak stopped. Then his shop roof collapsed under a snow load and he decided not to rebuild so he brought it to me. I couldnt get to it right away so my son tackled it. He pulled the engine out, put it on the stand and did a good job replacing the seal. It still leaked so now I tackled it.

There are many types of cylinders that one might run across on a farm scenario. Each one could take a chapter in
