Toolbox Test #19

Multiple Choice

A: Farmer A says it is a manufacturing code or part number, and it means nothing to the end-user.
B: Farmer B claims it is the liquid temperature in Fahrenheit degrees that the thermostat is fully open.
C: Farmer C tells you it is the crack-open temperature in Fahrenheit degrees when the thermostat begins to open.
D: Farmer D states that it is the size of the thermostat in millimeters.

Multiple Choice

A: Farmer A says the new pump is defective and has the same problem as the one you replaced.
B: Farmer B believes that the gauge is wrong, and the old pump was fine.
C: Farmer C says that the old pump ate some dirt from the tank, and it must still be in the system. That is why the impeller is damaged, and the volute pitted internally.
D: Farmer D is adamant that the original pump was damaged by cavitation, and that is why the pressure is jumping around.

Multiple Choice

A: Farmer A says that by idling the engine until it makes heat, you are decreasing the wear, and it is the smart thing to do if you want all your equipment to last.
B: Farmer B argues that it is the worst thing to do. You are wasting fuel and accomplishing nothing. When corn was $8/bushel, that was fine, but with $3.50 corn, you are crazy.
C: Farmer C is firm in stating that by warming-up an engine, you are creating excessive wear.
D: Farmer D claims it makes no difference what you do. All these new engines are junk and will not last like his old JD 4020, and 1972 Ford did.

Multiple Choice

A: Farmer A knows the truck stop and says that the tanks are less than six months old, so they must have got a load of dirty fuel.
B: Farmer B told you that the B-20 has a cleaning effect and loosened up all the sludge in your saddle tanks and put it into the filter.
C: Farmer C just said he does not know what happened, but you should never use B-20 unless the truck maker says so.
D: Farmer D has no idea, but chimes in that is why he never hauls grain too far.

Multiple Choice

A: Farmer A says that with a Flex-Fuel system, you can use gasoline with ethanol content up to E-85. He says that it is accomplished by using special head gaskets in the engine.
B: Farmer B agrees with Farmer A regarding E-85 but says it is not the head gaskets but unique fuel lines along with a sensor to determine the ethanol content in the gas.
C: Farmer C agrees with Farmer B but says there is more to it than fuel lines and a sensor. The engine control computer needs to alter the injector pulse width (opening) along with the ignition timing to accommodate higher proportions of ethanol.
D: Farmer D says he does not give a hoot! In the late 1970's he put gasohol in his VW Bug and burned up the engine.

About Ray

My name is Ray Bohacz, and I know that success on the farm is a three-legged stool: agronomy, business, and machinery. I have always believed and life has taught me, that great judgement in the first two areas can quickly be evaporated by poor decisions in the farm shop in regard to maintenance and repair.
