and install the vibration damper. tech B says if the inertia ring on the
vibration damper is loose, the damper must be replaced
A
B
Both
Neither.
Answer: Both
A special puller and installer tool are required to remove and install the
vibration damper. Using a regular gear puller to remove the vibration
damper will damage the damper.
Also, a loose inertia ring on the damper requires replacement of the
damper.
●● 5. if new rings are installed without removing the ring ridge, what
may be the result?
,-piston skirt may be damaged
-piston pin may be broken
-connecting rod bearings may be damaged
-piston ring lands and/or top compression ring may crack.
Answer: piston ring lands and/or top compression ring may crack
(failing to remove the ridge ring may cause piston ring lands and/or the
top compression ring to crack or break after the engine is assembled and
started)
-piston skirt & pin would not be damaged
-connecting rod bearings would not be affected
●● 6. when measuring the crankshaft journal (in the figure), the
difference between measurements:
A & B indicate horizontal taper
C & D indicate vertical taper
A & C indicate out-of-round
A & D indicate out-of-round.
Answer: A & C indicate out-of-round
-A&B indicate vertical taper
, -C&D indicate horizontal taper
-A&D do not indicate out-of-round
