I have a Kubota B7100 (gear) of the 1980's vintage. I would like to do a refurb of the whole tractor...tear down all sheet metal and repaint, new fittings and fasterners as needed, any new parts needed, etc. I am uncertain about what to do regarding the engine, however. It has a little under 2000 hours, and seems to run ok, but I am starting to see quite a bit of black smoke on start-up and under heavy load. Additionally, I am accumulating a lot of oil/crud on the engine surface that seems to "come back" soon even after cleaning.
I am reasonably good a mechanical stuff. Should I consider new seals and perhaps rings as part of a mini-refurb for the engine? I loaned it to a neighbor a couple of years ago and he brought it back with NO water in the radiator...said he couldn't keep it running for some reason. I found the radiator hose blown. Don't know what kind of damage that may of done, or if it is related to the issues described above. I have plenty of time and willingness to buy any special tools or parts to do the job myself. Suggestions welcome!
