What is the design type of the differential in the picture.
Integral
Removable
Limited Slip
Open
Locker
What is the design type of the differential in the picture.
Integral
Removable
Limited Slip
Open
Locker
Open differentials will limit the rotational speed differences between drive wheel.
True
False
Lockers will cause both drive wheels to turn at the exact same speed and torque.
True
False
Limited slip differentials will limit the rotational speed differences between drive wheel.
True
False
The function of the differential is: (Choose all Correct Answers)
To allow for a difference in drive wheel speed.
To provide a final gear reduction.
To provide good low-end acceleration.
Change gear ratios for different driving conditions
What type of gear set is shown in the picture
Spiral Bevel
Non-hunting
Hypoid
Hunting
During installation which gear set needs to be aligned up with timing marks?
Non-hunting
Hunting
Integral
Hypoid
Which type of gear set will cause every drive pinion gear tooth to contact every tooth on the ring gear?
Spiral bevel
Partially hunting
Hypoid
Hunting
Gear set backlash is:
The binding of two gears.
The free movement between gear teeth.
Moving the gears back in a rotational motion.
Cause by adding too much oil.
In order to increase gear backlash:
The gears need to be moved farther apart.
The gears need to be moved closer together
The gear oil level needs to be lowered.
Move the ring gear closer to the pinion gear.
Gears that don't have enough backlash will:
Bind during rotation.
Create an undesirable noise.
Wear out prematurely.
Break-in after 1000 miles of driving
What type of drive pinion is shown?
Overhung
Straddle Mount
What type of drive pinion is shown?
Overhung
Straddle Mount
The distance in the image represents?
Pinion angle
Ring gear drive size
Pinion depth
Backlash distance
In the image which way does the pinion have to move to increase pinion depth?
Up
Down
Left
Right
When discussing pinion movement and depth instead of saying up, down, left or right we should reference the position in relationship to the ring gear center-line.
True
False
The first "S" in the SSS rule stands for?
Straddle Mount
Smaller Specification
Smaller Shim
Single Shim
The second "S" in the SSS rule stands for?
Straddle Mount
Smaller Specification
Smaller Shim
Single Shim
The third "S" in the SSS rule stands for?
Straddle Mount
Smaller Specification
Smaller Shim
Single Shim
In order to apply the SSS rule you need to know and understand which two facts?
Pinion and shim movements for the overhung and straddle mount designs are opposite.
A smaller or larger specification is in reference to the measured pinion depth value.
The measured pinion depth value is always added to the specification.
A larger specification will always mean a larger shim is needed.
In the image, if pinion depth is decreased the shim thickness will be:
Increased
Decreased
