Removal and installation of the oil pump

Engine 2.0L

Remove the oil pump of a 2.0-liter engine in the following order:

• put the front of the car on trestle to gain access to the oil pan and oil pump;
• remove the oil pan (see subsection 4.1);
• unscrew the bolts of the oil pump housing;
• pull the pump down, the pump shaft gear should disengage from the countershaft gear, then pull it out completely;
• remove the ignition distributor (since it will still need to be removed when installing the pump).

Installing the oil pump is carried out in the reverse order of removal, subject to the following recommendations:

• when installing the oil pump on the crankcase, the gasket is not placed;
• tighten the pump mounting bolts with a torque of 20 Nm;

• before installing the ignition distributor, install the oil pump drive shaft mounting journal so that the trunnion is parallel to the longitudinal axis of the crankshaft (pic. 167);
• install the ignition distributor and tighten the mounting bolts to a torque of 20 Nm (see chapter 8.5.3).

• tighten the oil pump mounting bolts to a torque of 25 Nm, and the oil receiver bolts to 10 Nm;
• if the drive gear was removed, then insert it into the hole on the upper side so that it engages with the gear on the intermediate shaft;
• lubricate the cap and O-ring well with engine oil before installation;

• insert the drive shaft, install the O-ring seal on the cover (pic. 169);
• tighten the cover fastening bolts to 10 Nm;
• Install the oil pan and tighten the oil drain plug to 30 Nm.
