Remove the screws and remove the oil pump from the front cover (see. Fig. 2.44). Remove the oil pump gear to the front cover. Check Check the lubrication holes of the front cover in the absence of contamination and clean them if necessary. Inspect the balancer shaft bearing for wear, damage, or jams. If the bearing is faulty, replace the front cover. Check the front cover for cracks or damage and replace it if necessary. Inspect the crankshaft oil seal for worn or damaged working edges, if necessary, replace it. Check elongation of a spring ring, compression sealing lips of oil seal, and, if necessary, replace the oil seal. Check the oil pressure sensor. Install the oil pump gear to the front cover, and turning them ensure smooth rotation and the absence of backlash. Check the surface of the gear teeth for wear or damage. check for wear mating surfaces of the front cover and oil pump cover.

|
Metal ruler and a feeler gauge, measure the backlash gear oil pump (Fig. 2.104). Nominal backlash oil pump rotors - 0,040-0,095 mm. Check for smooth movement of the plunger of the safety valve. Check the safety valve spring for deformation or cracks. Check the oil pan and the oil strainer for any damage, injury or fracture, if necessary, replace them. Setting Install the oil pump and gasket. Tightening torques in Nm: Bolts of fastening of the oil pump housing ..... 12-15 Screws oil pump ..... 8-12 Special tools (09214- 33000) set the seal into the oil pump housing. Install the plug and the spring of the safety valve, screw the drain plug torque 40-50 Nm. Install the oil strainer with a new gasket and tighten the bolts to 15-22 Nm. Clean the gasket surfaces of the cylinder block and oil pan. Apply a layer of sealant into the groove of the oil pan flange.
WARNINGS The sealant must not protrude more than 4 mm from the groove oil pan flange. Install the oil pan within 15 minutes after sealant application. Make sure that the sealant has not got into the oil pan. Place the upper section of the oil pan and tighten the bolts (Fig. 2.105). |
