Additional Torque Notes
1) Always use the torque values listed on the previous page when speci c torque values are not
available.
2) The torque values are based upon the use of clean, dry threads.
3) Reduce torque by 10% when engine oil is used as a lubricant.
4) Reduce torque by 20% if new plated capscrews are used.
5) General formula for calculating Torque is as follows: Torque in Inch Lbs = 0.2 x Nominal
diameter of Screw x Load in Lbs., where Load = 80% of Yield Strength, expressed in Lbs., not in
pounds per square inch.
ELECTRICAL REPAIR
Electrical Testing
The electrical system used on this unit consists of various lights, switches and wiring. Testing the
component and wiring can be accomplished by two simple checks; CHECKING FOR VOLTAGE and
CHECKING FOR CONTINUITY. It is important to perform regular electrical testing on your machine in
order to prevent incidents or malfunctions while on route. Proper electrical maintenance and testing
will ensure the Quantum unit has less down time.
Checking for Voltage
A test light is used to check for the presence of electricity in live circuits. Connect the test light clip to
a good ground and the probe at the point where the presence of voltage is to be checked. If voltage
is present, the light will be on… if no voltage is present, the light will be o .
Checking Continuity
A continuity tester is used to check the ability of a conductor to allow current to pass. A continuity
tester uses a self-contained power source, and should never be used on a live circuit. Connect the
clip to one side of the component to be tested and touch the probe to the other side. If the compo-
nent has the potential to pass current, has continuity, the tester will register accordingly.
