Removal and installation of oil. pump
Removing the lower part of the oil. crankcase. Unscrew the "arrow" screw and remove the oil separator.
Move the chain tensioner spring using the "T10118" tool in the "direction of the arrow" and secure it with the "T40265" lock.
Unscrew the "arrow" bolts and remove the oil. pump.
Installation
Installation in reverse order. Check the presence of both oil pan centering bushings. pump. Remove the "T10118" tool, and the spring will return to its mounting position. position. Install the seal. ring on the new oil damper and lubricate it with oil. Install the new oil separator and secure it. Install the lower part of the oil. pan. Fill with oil and check its level.
Removal and installation of oil. pallet
Remove the gearbox. Remove the electric mechanical power steering. Removing the lower part of the oil. crankcase. Remove the rear seal. flange. Remove the oil pump. Disconnect connector "1".
Unscrew the arrow bolts.
Unscrew bolts "1...14" and remove the upper part of the oil. pan. First, unfasten the top part of the oil pan. the oil pan is located on the transmission side. When removing it, proceed with caution to avoid deforming the timing chain cover.
Installation
Upper part of the oil. the tray must be installed within 5 minutes after applying the silicone sealant. Replace bolts that were tightened with additional tightening. Replace all seals, gaskets and self-locking nuts. Remove any remaining sealant from the cylinder block using a flat scraper. Remove any remaining sealant from the top of the oil. sump, for example, using a drill with a rotating plastic brush attachment. Make sure the timing chain cover is not deformed. To do this, first install the upper part of the oil pan. pump without using sealant and check the gap between the lining and the top of the oil. if deformation is detected, or the cover cannot be aligned, replace the cover, first installing the upper part of the oil pan. pallet. Clean the seating surfaces; there should be no oil or grease on them. Check the oil passages of the upper part of the oil. the sump and cylinder block for contamination. Cut off the tip of the tube along the front mark (hole diameter is about 3 mm). Apply oil to the clean seating surface of the top. silicone sealant on the oil pan, as shown in the illustration "arrow". Sealant bead thickness: 2 - 3 mm.
The sealant strip must not be thicker than the specified width, otherwise excess sealant may get into the oil pan and clog the mesh filter in the oil intake pipe. From the gearbox side, the upper part of the oil. the oil pan and engine crankcase must be flush. Install the top part of the oil immediately. pan and tighten the bolts, then tighten the tightening bolts. Screw in the "arrow" bolts. Install the rear seal. flange.
Install oil. pump. Install el. mechanical power steering. Installation in reverse order. Fill with oil and check its level.
