When discussing the various gear positions of a transfer case, Technician A says that when the transfer case is in low, the overall gear ratio is numerically increased. Technician B says that when the transfer case is in the high position, the vehicle operates in an overdrive mode due to the decrease in torque multiplication. Who is correct?
Explanation Need.
WHEN A TRANSMISSION IS IN OVERDRIVE:
A. THE OUTPUT SHAFT TURNS FASTER THAN THE ENGINE. (POSSIBLE CORRECT AWNSER)
B. THE INPUT AND OUTPUT SHAFTS BOTH TURN FASTER THAN THE ENGINE SPEED. (NOT CORRECT AWNSER)
C. THE REAR WHEELS TURN FASTER THAN THE ENGINE.
D. THE OUTPUT SHAFT TURNS SLOWER THAN THE INPUT SHAFT.
Technician A says that side-bearing preload limits the amount the differential case is able to move laterally in the axle housing. Technician B says that adjusting backlash sets the depths of the mesh between the ring and pinion gears’ teeth. Who is correct?
