AURTTA105 Select and use bearings, seals, gaskets, sealants, and adhesives 17. What is a thrust bearing? A thrust bearing is a type of bearing designed to handle axial or thrust loads, which are forces that act parallel to the axis of rotation. Unlike other types of bearings that primarily handle radial loads (forces acting perpendicular to the axis), thrust bearings are specifically engineered to support and transmit axial loads. 18. Explain what are antifriction bearings? Antifriction bearings, also known as rolling element bearings, are a type of bearing designed to reduce friction between moving parts in a mechanical system. These bearings employ rolling elements, such as balls or rollers, that facilitate smooth motion by rolling between the stationary and rotating components of a machine. The rolling motion of these elements minimizes sliding friction, resulting in improved efficiency and reduced wear. 19. Why are sealed bearings used? Sealed bearings are used in various applications to provide additional protection and advantages compared to open bearings. Sealing is employed to prevent contaminants, such as dust, dirt, moisture, and other foreign particles, from entering the bearing assembly. 20. Name the ten [10] engine assembly gaskets, seals and grommets below. 1 Grommets 2 Thermostat housing gasket 3 Intake manifold gasket 4 Intake manifold end seal 5 Cylinder head gasket 6 Valve cover gasket 7 Oil pan gasket 8 Timing cover gasket 9 Front crankshaft seal 10 Water pump gasket Document Name: Student Written Questions – AURTTA105 Version: 2.0 © Strathfield College | RTO Code: 91223 | CRICOS Code: 02736K Page Sequence: Page 11 of 23

AURTTA105 Select and use bearings, seals, gaskets, sealants, and adhesives 21. Why are oil seals used? Oil seals, also known as shaft seals or rotary shaft seals, are used in various mechanical systems to prevent the leakage of fluids, typically lubricating oil or grease, from the internal components of a machine. They are designed to maintain a barrier between the moving parts and the external environment.

AURTTA105 Select and use bearings, seals, gaskets, sealants, and adhesives Multiple choice. Circle all the correct answer 30. Gaskets are made from. A. Cork and cork composition. B. Special jointing materials. C. Fibre and nylon. D. Synthetic rubbers. E. Steel core and composition. F. Metal gaskets. G. All answers are correct. 31. Why are gaskets needed? Gaskets are needed for several important reasons in various mechanical and industrial applications. They play a crucial role in ensuring the proper functioning, safety, and reliability of equipment and systems. Gaskets function as a seal where two separate engine parts meet. They provide a barrier that keeps unwanted liquids or gases from mixing inside your engine. 32. Describe the following basic types of gasket construction. Plain gaskets: A plain gasket, also known as a flat gasket or full-faced gasket, is a simple type of gasket that consists of a flat, uniform piece of material without any specialized features or intricate designs. Plain gaskets are typically used to create a sealing surface between two flat or slightly curved mating surfaces, such as flanges or connections in pipelines, valves, and machinery. Layered gaskets: Layered gaskets, also known as laminated gaskets or composite gaskets, are a type of gasket construction that involves multiple layers of different materials combined to create a single gasket assembly. Each layer serves a specific purpose, contributing to the gasket's overall sealing performance. Layered gaskets are used in applications that require enhanced sealing capabilities, such as high pressure, high temperature, or aggressive chemical environments.

AURTTA105 Select and use bearings, seals, gaskets, sealants, and adhesives Bonded gaskets: Bonded gaskets, also known as adhesive-bonded gaskets or adhesive-backed gaskets, are a type of gasket construction where a layer of adhesive or bonding material is applied to one or both sides of the gasket. This adhesive layer serves to attach the gasket to the mating surfaces or components, providing several advantages in terms of installation, alignment, and sealing performance. Embossed (corrugated) steel gaskets: Embossed steel gaskets, also known as corrugated steel gaskets or corrugated metal gaskets, are a type of gasket construction that involves using a thin metal sheet with corrugated or wavy patterns to create a sealing structure. These gaskets are commonly used in high-pressure and high-temperature applications where a combination of mechanical strength and effective sealing is required. 33.

They work by filling in the small gaps between the threads with a ______ fluid_________ that cures or ‘sets’ in the absence of ________ air_______. This is known as anaerobic cure. They are useful for fasteners that cannot be checked after _____ assembly__________, such as flywheel bolts. 3 Gasket sealants. Some gaskets are coated with a ______ sealant_________ just prior to assembly. This fills the small spaces between the _____ component__________ and the gasket. The sealant is normally applied to the removable part, for example, between the _______ rocker________ cover and the gasket. They also help to keep the gasket in place during assembly. 4 RTV silicone sealants. These ______ silicone _________ sealants cure or vulcanise at room temperature (RTV). They can be used in place of a ______ gasket_________ to produce formed-in-place gaskets. 5 Retaining compounds. These are anaerobic _______ liquids________ that can be used for applications such as between the inner race of a ______ bearing_________ and its shaft, or between the outer race of the bearing and its housing. This secures the bearing in place and compensates for any minor ______ clearances_________ in the parts. Catalytic action between the parts assists with curing. True or False question 35. A gasket adhesive does not add to the gasket’s sealing ability. ☐ True or ☐ False Fill in the Missing Word 36. Place the missing word to complete the following statement about gasket adhesives using the following words. Missing Words : Adhesives, bond, components, during, gasket Gasket adhesives form a tough _______ bond________ when used on clean, dry surfaces. _____ adhesives__________ do not aid the sealing ability of the ______ gasket_________.

AURTTA105 Select and use bearings, seals, gaskets, sealants, and adhesives 2 Thoroughly clean all bearing components using appropriate cleaning solutions or solvents. Ensure that the cleaning agent is compatible with the bearing material and won't cause damage. Use a soft brush or lint- free cloth to remove dirt, grease, and any other contaminants from the inner and outer races, rolling elements, and cages. 3 Inspect the cleaned bearing components for signs of wear, damage, or defects. Pay close attention to the rolling elements, raceways, and cage. Look for indications of pitting, cracking, corrosion, or other abnormalities. Also, check for proper lubrication and signs of overheating, such as discoloration. 4 Measure critical dimensions of the bearing components, including internal and external diameters, clearances, and axial play. Refer to the manufacturer's specifications to ensure that the measurements are within acceptable tolerances. If the components pass inspection, reassemble the bearing assembly with new or reconditioned parts as necessary. Apply the appropriate type and amount of lubricant, following the manufacturer's recommendations. 38. What is meant by bearing preload? Bearing preload refers to the intentional application of a controlled axial force or tension to a bearing in order to remove any internal clearances or play between the bearing's components. It's the practice of applying a slight axial load to the bearing components before installation to eliminate any initial looseness or slackness in the rolling elements, raceways, and cage. This can improve the bearing's performance by minimizing internal movement and ensuring proper contact between the rolling elements and raceways. 39. Describe briefly how front-wheel bearings of a rear wheel-drive vehicle would be adjusted. Adjusting front-wheel bearings of a rear-wheel-drive vehicle involves ensuring the proper amount of bearing play to prevent excessive friction, overheating, and premature wear.The bearing is adjusted by tightening the hub nut if it is too loose, or loosening the nut if it is too tight. It should be done with the wheel on and raised on an axle stand. Rock the wheel from side-to-side and top-to-bottom to check for bearing wear.
