I just put new rings in my Farmall 100. Got the head off being worked on so figured I'd do the rings whether it needed them or not. Tractor is new to me so I don't know what has been done in the past. Still have the head off. I can turn the engine with the crank but it turns hard as I would expect with new rings. Should I do anything for lubrication while I got it apart to make it turn easier or is it just a matter of getting it broke in once I get it running. This whole thing started with low compression. Hope to have the head back this week and have it running for the first time this weekend.
