A plentiful supply of inexpensive old farm tractors translates into a growing interest in the tractor restoration hobby. But getting that old engine to turn over can be a long row to hoe. Internationally recognized tractor expert Spencer Yost guides readers through all the ins and outs of restoring old tractor engines, from removal to reinstallation. After helping readers set up shop, Yost explains how to determine when to replace and when to rebuild parts, and offers expert opinions on tasks that can be done at home and those that should be farmed out to shop pros. The book covers the most popular two-, four-, and six-cylinder gas-burning engines, with special sections on diesel and propane-powered tractors. An appendix lists parts suppliers, reference materials, and restoration shops.
