Show CLEAN OIL OFFERS BEST MAINTENANCE Fuel and repair cost are becoming so expensive that it behooves farmers and ranchers to get the most performance possible from their tractors. Extension farm machinery ma-chinery specialist, Von H. Jarrett, with Utah State University Uni-versity says it is naturally natural-ly good business to do what is possible to accomplish more work with less time and fuel. Most important are regular engine tune-ups tune-ups where checks and m inor adjustments are made to improve im-prove the operation of the machine. He said, "Unfortunately most operators make the mistake of performingtune-up performingtune-up only when the engine is not running as it should. This is often a costly error because at this point the engine en-gine may be worn or dam -aged until it requires a major repair or overhaul. This can be very costly. "The intervals for tune-up tune-up may vary from 500 to 1,000 hours each spring and fall depending upon the operating op-erating conditions. But regularity reg-ularity is the key to tuning tun-ing the engine so that major problems are prevented." The extension specialist pointed out that a badly worn engine cannot be tuned up. He recommends that the engine en-gine be checked on a dynamometer dyna-mometer to see if a tune-up tune-up will restore its efficiency, ef-ficiency, or if a major overhaul is needed. This check must be done by someone who can be trusted trust-ed to give an unbiased accurate evaluation. A dynamometer, such as the one purchased by USU Extension, attaches to the powertakeoff of the tractor trac-tor to test it under load. It is metered to indicate horsepower output and engine en-gine speed that can be com -pared to the manufacturer's manufactur-er's recommendation. It Is used in checking and adjusting ad-justing the following: (0 valves, spark plugs and compression; (2) ignition timing; (3) timingandpump setting on a diesel engine; (4) carburetor; (5) main clutch; (6) fuel pump; (7) clean air supply; and (8) condition of rings as seen in blowing from crankcase. After performing a tune -up, Jarrett advised that the tractor be run on the dynamometer again to see the change in performance. He said tractor value in terms of the cost when purchasing pur-chasing one is about $200 per horsepower. In his experience ex-perience at taking the dynamometer dyna-mometer ou t into the counties, it has not been unusual to save thousand dollars value on tractors by improving their efficiency ef-ficiency and bringing their . horsepower output up near to the machine's potential. This makes it possible to accomplish more work with less time and less fuel. |
