replacement sprocket? - ANSWER ✔ D80C20
7. What amount of chain sag as a percentage of distance between shaft centers
indicates that the tension of a multiple-strand chain drive is set correctly? -
ANSWER ✔ 2-4%
,8. What type of V-belt replaces a conventional v-belt using the same sheaves
but with higher effeciancy, longer life, and cooler operation? - ANSWER
✔ Wedge
9. What tool is used to shorten a roller chain? - ANSWER ✔ Chain breaker
10.What machine feature is required when using moveable machine guards but
not when using flex guards? - ANSWER ✔ Guard Interlock

✔ Grid couplings allow for more misalignment because they are
torsionally more flexible
14.Which of these condition indicates that v-belt drive sheave needs to be
replaced? - ANSWER ✔ Belt rides more than 1/16 inch below the outer
edge of the sheave groove
15.What can cause a chain to ride high on the teeth of a sprocket? - ANSWER
✔ Inadequate Lubrication and Excessive Speed

machine and put the guard on
17.Which safety dress/PPE guideline may not always be necessary when
working around rotating machines? - ANSWER ✔ Employ respiratory
equipment
18.Which machine feature is essential when employing movable machine
guards but not needed when using fixed guards? - ANSWER ✔ Guard
interlock
, 19.How many locks are necessary to lock out a machine with a single energy
source when two mechanics and one electrician will be involved in repairing
the machine? - ANSWER ✔ 3 locks, one for each person performing the
work
20.Among the listed power transmission systems, which one does not present
the risk of a nip point? - ANSWER ✔ Two shafts connected with a flange
coupling
21.What method is advised for lifting heavy power transmission components? -
ANSWER ✔ Maintaining a straight back, bending knees, and lifting with
legs
22.What are the essential steps a maintenance technician should take before
removing a machine guard to repair a machine? - ANSWER ✔
Lockout/Tagout machine
23.What is the next move after bypassing a guard? - ANSWER ✔ Lock out
the machine
24.What is the role of a mechanical power transmission bushing? - ANSWER
✔ Connects a sheave or sprocket to a shaft
25.What is a frequently encountered mistake during the installation of a taper
lock bushing? - ANSWER ✔ Aligning the threaded holes on the bushing
with the threaded holes on the hub
26.In a shaft alignment procedure, which form of shaft misalignment is rectified
as the initial priority? - ANSWER ✔ Vertical angular
27.What technique should be used when lifting heavy power transmission
components? - ANSWER ✔ Keep back straight, bending knees, while
lifting with legs
28.Which of the following is the coupling that would be used to combine two
short shafts to replace a long straight shaft? - ANSWER ✔ A rigid
coupling
