- Technician A says that piston ring end gaps should be the same for each ring on a piston. Technician B says that piston ring end gaps should be aligned before installing the piston into its bore. Who is correct? Technician A Technician B Both A and B Neither A nor Barrow_forwardWhen removing the piston and rod assemblies from a cylinder block; Technician A positions the throw of the crankshaft at the top of its stroke and removes the connecting rod nuts and cap. Technician B covers the rod bolts with protectors and pushes the piston and rod assembly out with the wooden hammer handle or wooden drift and supports the piston as it comes out of the cylinder. Who is correct? Technician A Technician B Both A and B Neither A nor Barrow_forwardWhile discussing what affects the amount of pressure exerted by the brakes: Technician A says that the shorter the line, the more pressure there will be. Technician B says that braking force will increase if the size of the pistons in a master cylinder are increased. Who is correct? Technician A only Technician B only Both A and B Neither A nor Barrow_forward
- While discussing the common causes for cracks developing in a cylinder block or head: Technician A says that the chilling of a hot engine by a sudden rush of cold water or air over the surf ace may cause cracking. Technician B says that excessive overheating is a common cause. Who is correct? Technician A Technician B Both A and B Neither A nor Barrow_forwardWhile discussing the reasons for resurfacing a cylinder head; Technician A says it should be resurfaced to make it flat and very smooth so the head gasket can seal properly during engine assembly. Technician B says that it can be resurfaced to raise the compression. Who is correct? Technician A Technician B Both A and B Neither A nor Barrow_forwardTechnician A says that crankshaft counterweights offset the weight of the connecting rods and pistons. Technician B says that crankshaft counterweights are used to dampen crankshaft torsional vibrations. Who is correct? Technician A Technician B Both A and B d. Neither A nor Barrow_forward
- Which of the following statements is incorrect? Cylinder head bolts must be tightened to the proper amount of torque. Most cylinder head bolts are tightened in a sequence that starts on one end. On some engines, the head bolts are retorqued after the engine has been run and is hot. Many engines use head bolts of different lengths.arrow_forwardWhile diagnosing the cause for an engine having good results from a compression test and cylinder leakage test but poor results from a cylinder power balance test: Technician A says that incorrect valve timing is the most likely cause. Technician B says that a severely worn cam lobe is a likely cause. Who is correct? Technician A Technician B Both A and B Neither A nor Barrow_forwardWhy must a cylinder ridge be removed before attempting to remove the piston?arrow_forward
- Which of the following is not of concern when checking a piston? Diameter Surface finish Groove wear Pin boss wobblearrow_forwardWhere does maximum cylinder bore wear occur and whyarrow_forwardHow does cushioning affect the speed of the piston when the cylinder is cushioned at end of the stroke? which one correct ? 1-cushioning increases the speed of piston at the beginning of the stroke 2- cushioning increases the speed of piston near the end of the stroke 3-cushioning decreases the speed of piston at the beginning of the stroke 4-cushioning decreases the speed of piston near the end of the strokearrow_forward
