Trades & Technology - Automotive; Pace 5 Quiz
1
When the electricity to the transfer case clutch coil is stopped, a voltage spike that can ruin the PCM is produced.
2
The detent stops the shifter from engaging more than one gear.
3
To check axle shaft endplay, grip the driveshaft and turn each wheel in both directions.
4
Except for independent suspension types, the axle shaft must pass through the front spindle to drive the front wheel.
5
Most front-wheel-drive vehicles use a sealed adjustable front wheel bearing.
6
The synchronizer struts ride in slots on the outer sleeve.
7
The two most popular types of transfer cases are gear and chain drives.
8
Abnormal clutch failure is the results of bell housing misalignment.
9
Planetary gear set can be used as a center differential inside a transmission case.
10
Voltmeter measures voltage and are connected in series on most 12 volt system.
11
There is no difference between a mode shift and a range shift.
12
The blocker rings are used to control end play for the speed gears.
13
4WD is used only for improved traction while operating off road.
14
With most pickup based 4WDs, the input shaft of the transfer cases is coupled directly to the transmission mainshaft.
15
Preload causes a slight drag as a shaft is rotated and can cause bearing damage.
16
Ground in a car's electrical circuit provides an electrical path to return to the battery.
17
Ammeters measure current and must be connected in parallel in the circuit.
18
To check axle shaft endplay, grip the driveshaft and turn each wheel in both directions.
19
A typical transfer case will have one input and two output shafts.
20
Speed sensors can be either magnetic or Hall-effect-type sensors.
21
An open circuit will cause the fuse to blow out.
22
The voltage-generating speed sensor normally uses a three-wire connector and is checked using both and ohmmeter and a voltmeter.
23
On overhung pinion arrangement, replacing the pinion shim with a thicker shim will move the pinion closer to the ring gear.
24
Circuit tester include test lights and fused jumper leads.
25
A relay is essentially a switch that is operated by a magnetic coil.
26
Pinion preload can be checked using a dial indicator.
27
The problem with a speed sensitive noise that is affected by the type of road but not the throttle is in the axle bearings.
28
A clutch spin-down test should be performed with the engine off.
29
A 3:5 ring and pinion gear set is classed as a hunting gear set.
30
Gears and bearing can be damaged in just a few days if operated with very low lubricant level.
31
It is always a good practice to replace the side bearings when replacing the pinion seal.
32
An expectable amount of pinion bearing preload is 0.008 to 0.012.
33
The letter W is the viscosity rating when the oil is cold.
34
The radial clearance of a needle bearing is not adjustable.
35
To move the pinion gear deeper into the ring gear; you can install a thicker pinion depth shim.
36
Parts must be cleaned before being inspected.
37
The fluid level on all Ford axles should be a specified distance below the opening and requires a special dipstick.
38
Ring gear backlash must be adjusted when ever the pinion seal is replaced.
39
The toe of the ring gear teeth is toward the center of the ring gear.
40
While coasting, the backlash will be at the concave side of the ring gear.
41
The convex side of a ring gear tooth is the coast side.
42
A pair of roller bearings called carrier bearings are used to locate the pinion gear and the differential and ring gear.
43
All semi-floating axles use bearing retained axle arrangement.
