Checking the clearance between the pump gears with a feeler gauge is shown in fig. 3.20 a. New pump clearance: 0.05 mm, allowable wear: 0.20 mm.
Checking the axial clearance of the oil pump is shown in fig. 3.20 b. Permissible wear: 0.15 mm.
Checking the tension of the oil pump drive chain is shown in fig. 3.20 in. Deflection «A» should be: when checking - 4.0-5.0 mm, when adjusting - 3.5-4.5 mm.
