Correct Answer and Feedback
6.
B.
3 to 5 minutes.
The engine must be allowed to properly cool prior to being shut
off. Any period of time shorter would not allow for sufficient
cooling, especially the turbocharger. A longer time period would
cause the engine to load up with fuel and build carbon. (Page
17, para 4)
7.
B.
To prevent contamination from entering the system.
Cap the lines to prevent dirt and contaminates from entering the
system. This would cause excessive wear on the components of the
system or even clog the system and prevent operation. (Page 18,
para 1)
8.
C.
22 to 26 inch pounds.
If you apply the incorrect torque to the screws, you would be
running the risk of breaking or stripping the screws, or the not
securing the liquid level transmitter properly. (Page 22, para
5)
9.
A.
Sealant.
Sealant is the sealing substance listed.
Use Teflon tape for
some applications, but not this one. (Page 27, para 11)
10.
B.
3/8 to 5/8 inches.
If the deflection in the belts is less the 3/8", they are too
tight and would cause excessive wear on the shaft bearings. If
the deflection in the belts is more than 5/8", they would be too
loose, causing slippage and the pump not function correctly.
(Page 38, para 8)
11.
A.
MASTER switch on, flow control valve open.
This is the correct normal operating position for the MASTER
switch and flow control valve. If they are not in this position,
a fault would be indicated when one did not exist.
(Page 42,
para 10 and page 43 para 6)
12.
B.
Replace the switch.
When continuity is not indicated in a switch, it is defective.
If there is no path for the current to flow, it must be replaced.
