Question 1

What should be used to check the thickness of a thrust washer, and the thickness should be compared to the vehicle manufacturer's specifications.

Accepted Answer

A micrometer is a precision measuring instrument used to measure small distances or thicknesses, such as the thickness of a thrust washer, with high accuracy.

Question 2

When reinstalling _________ in an automatic transmission, apply a small amount of transmission assembly lube to hold them in place.

Accepted Answer

Both thrust bearings and thrust washers can benefit from a small amount of transmission assembly lube to hold them in place during reinstallation in an automatic transmission.

Question 3

Which of the following cannot easily be completely disassembled?

Accepted Answer

The answer of Which of the following cannot easily be...

Question 4

Which of the following component can be only partially disassembled?

Accepted Answer

The answer of Which of the following component can be...

Question 5

Rollers or races that show any signs of damage must be replaced, and the lubrication circuit for the one-way roller should be carefully inspected for blockage.

Accepted Answer

Damaged rollers or races can lead to equipment failure, and a blocked lubrication circuit can prevent proper functioning, so both issues must be addressed to ensure safe and efficient operation.

Question 6

Techncian A says preload refers to the amount of force placed on a bearing before any working load is exerted on the bearing. Technician B says free play refers to the amount that a bearing is able to move before hitting the bearing race. Who is correct?

Accepted Answer

Technician A is correct because preload is indeed the force applied to a bearing before any external load is applied. Technician B is also correct because free play refers to the movement allowed in a bearing before it contacts the race.

Question 7

A ________ should be used to check the thickness of a thrust washer, and the thickness should be compared to the manufacturer's specification.

Accepted Answer

A micrometer is a precision measuring tool used to measure small distances or thicknesses, such as the thickness of a thrust washer, with high accuracy.

Question 8

When reinstalling thrust bearings or washers in a transmission, apply a small amount of ______ to help hold it in place.

Accepted Answer

Transmission assembly lube is specifically designed to hold parts in place during assembly and provide initial lubrication, making it the appropriate choice for reinstalling thrust bearings or washers in a transmission.

Question 9

On a one-way roller, the unit should be disassembled to inspect each individual roller. The roller should be checked for _________, such as in a wheel bearing.

Accepted Answer

All the mentioned issues - pitting, scoring, and brinelling - are types of wear or damage that can occur in bearings and should be checked during inspection.

Question 10

All of the following statements with respect to the inspection of mechanical diodes are true except:

Accepted Answer

The end of the struts will not become smoother as they wear; instead, they may show signs of wear such as roughness or deformation.

Question 11

Tech A says that a one-way roller clutch will work fine if assembled in either direction. Tech B says that sprag clutches must be serviced as a complete unit if any damage is found. Who is correct?

Accepted Answer

A one-way roller clutch must be assembled in the correct direction to function properly, while sprag clutches typically need to be serviced as a complete unit if damaged.

Question 12

All of the following statements are true with respect to sprag clutch inspection except:

Accepted Answer

Sprag clutches have a specific direction of assembly to function correctly, so they cannot be assembled in any direction.

Question 13

Tech A says that when assembling a transmission, the components should be lubricated with the correct automatic transmission fluid or transmission assembly lube. Tech B says that the transmission end play needs to be measured after the front pump is installed. Who is correct?

Accepted Answer

Both Tech A and Tech B are correct. Proper lubrication is essential during assembly to ensure smooth operation and prevent wear. Measuring transmission end play after installing the front pump is a standard procedure to ensure proper clearance and function.

Question 14

Tech A says that when inspecting the torque converter, you need to check the snout of the converter where the seal and bushing rides for excessive wear. Tech B says that the end play of the converter must be checked. Who is correct?

Accepted Answer

Both Tech A and Tech B are correct. Checking the snout for wear and the end play of the torque converter are both important steps in inspecting a torque converter.

Question 15

Tech A says that the torque converter should be bolted to the flexplate before installing the transmission. Tech B says that when installing the torque converter, three separate engagements with their mating parts must be felt. Who is correct?

Accepted Answer

Tech B is correct because when installing the torque converter, it must engage with the input shaft, stator support, and pump drive, which are the three separate engagements that should be felt. Tech A is incorrect because the torque converter is typically installed onto the transmission first, and then the assembly is bolted to the flexplate.

Question 16

Tech A says that to determine whether roller-type thrust bearings need to be replaced, they should be measured with a micrometer. Tech B says that to determine whether thrust washers are worn excessively, they should be measured with a micrometer and compared to specifications. Who is correct?

Accepted Answer

Tech B is correct because thrust washers can be measured with a micrometer to check for excessive wear by comparing the measurements to the manufacturer's specifications. Roller-type thrust bearings are typically inspected visually or by checking for play, not measured with a micrometer.

Question 17

Bushings must be replaced when clearance exceeds:

Accepted Answer

Bushings typically need replacement when the clearance exceeds 0.003" (0.076 mm) as this indicates excessive wear that could affect performance.

Question 18

Discoloration of the planetary gears or the planet carrier can be a sign of:

Accepted Answer

The answer of Discoloration of the planetary gears or the...

Question 19

Choose the correct statement.

Accepted Answer

Planetary gear sets are typically very durable components in a transmission and often do not require service during a rebuild unless there is a specific issue.

Question 20

Use a feeler gauge to measure the amount of clearance on the planetary gears. If the clearance is not correct, install:

Accepted Answer

A feeler gauge is used to measure the clearance, and if the clearance is incorrect, adjusting the thickness of the thrust washer can correct the clearance.
