- While discussing camshafts Technician A says valve lift is based only on the height of the cam lobe. Technician B says valve duration is based on the height of the lobe. Who is correct? a. Technician A b. Technician B c. Both A and B d. Neither A nor Barrow_forwardTechnician A says off-square springs may cause increased stem-to-guide wear. Technician B says excessive spring tension may cause premature camshaft wear. Who is correct? Technician A Technician B Both A and B Neither A nor Barrow_forwardTechnician A says that delayed shifting can be caused by worn planetary gearset members.

- While checking a hydraulic phaser after the camshaft has been removed from the engine: Technician A attempts to rotate the phasers timing gear by hand and replaces it if it does not move.

Technician A Technician B Both A and B Neither A nor Barrow_forwardPinion gear-to-flywheel ring gear clearance is being discussed: Technician A says that if there is too much clearance, there will be a high pitch while the engine cranks. Technician B says that if there is too little clearance, there will be a high pitch noise after the engine is started. Who is correct? Technician A Technician B Both A and B Neither A nor Barrow_forwardWhen discussing shift problems,Technician A says that worn or broken engine and transaxle mounts can cause a transaxle to have shifting problems.Technician B says that poor shift boot alignment can cause a transaxle to jump out of gear?arrow_forward
- Tech A states to check the camshaft for lift, the cam must be removed from the engine. Tech B says to check for a bent camshaft, the cam must be removed and placed onto a set of V-blocks and checked with a dial indicator.
