Question 1

Housing joint leaks are generally contributed to faulty gaskets.

Answer 1

false;

Question 2

As a maintenance concern, on which shafts should the end play be checked?

Answer 2

input shaft and c) output shaf

Question 3

When performing a road test, it was discovered that there was a noise that only
occurred while cornering. The probable cause is:

Answer 3

worn carrier thrust washers

Question 4

What check must be done before disassembling the carrier assembly?

Answer 4

backlash

Question 5

Why must caution be used when removing the case half bolts?

Answer 5

If the carrier is equipped with a no-spin traction enhancing device, the case halves
will be spring-loaded and longer bolts will have to be used to relieve the spring
tension.

Question 6

Which components should always be changed in sets?

Answer 6

bevel gear and pinion gear.

Question 7

When the operator activates the driver controlled carrier lock, the operator is
mechanically locking:

Answer 7

one axle shaft to the carrier case

Question 8

Pinion bearing preload is established with:

Answer 8

shims between the pinion bearings.

Question 9

When checking pinion bearing preload using a cord and a spring scale, record the reading required to start the assembly rolling.

Answer 9

false;

Question 10

The specific distance that the pinion and bevel gear are designed to run from each
other is called:

Answer 10

nominal distance.

Question 11

Side bearing preload and backlash adjustment is done with:

Answer 11

threaded bearing adjusters.

Question 12

When adjusting the backlash between the pinion and the bevel gear, if more backlash
is required:

Answer 12

adjust the flanged half adjuster counter-clockwise and the plain half adjuster
clockwise the same amount

Question 13

. If the tooth contact pattern shows excessive heel:

Answer 13

move the ring gear toward the pinion.

Question 14

When reusing a gear set, the shim pack thickness that was removed during disassembly can be discarded. T/F

Answer 14

False, the shim pack should be reused.

Question 15

Where should a 0 etch marked pinion be positioned?

Answer 15

At the nominal dimension

Question 16

After the backlash is properly set, the bearing cap fasteners can be torqued to specifications. What should be done after this?

Answer 16

Recheck the backlash; if correct, lock the adjusting rings in place.

Question 17

2 basic ways of lubricating carrier components are:

Answer 17

Splash pressure and combination splash and pressure systems.

Question 18

Which component splashes oil to the wheel bearings and drive pinion?

Answer 18

The bevel gear splashes oil around in the carrier housing troughs and passages for lubrication in hard to lube areas.

Question 19

Pressure lubrication pump is driven at what speed?

Answer 19

This pump is driven in an over drive to ensure adequate lubrication for the bearings and gears.

Question 20

What are some common housing joints failures?

Answer 20

O ring seals and RTV sealants that are used in the carrier housings due to loose bolts, stressing, high torsional loadings and imperfections in the mating surfaces.

Question 21

Bevel gear and pinions must be replaced individually?

True or false

Answer 21

False

Question 22

How is pinion bearing preload established ?

Answer 22

Shims

Question 23

When measuring pinions bearing preload, how should you read the spring scale?

Answer 23

Read the spring scale torque while rolling rather than torque required to start rolling
