Oil Pan Installing; Oil Pump - Mitsubishi 4DQ50 Service Manual

9 OIL PAN INSTALLING
Oil pan of Model 40Q50 Engine is designed so as to be installed with its center in
alignment with those of crankcase and crank shaft. At either end, fasten it tight enough not
to leak.
Main bearing caps on both front and rear ends have grooves. Fit retainers in those
grooves as illustrated in Fig. 5-13. Then, to their corners, put the ends of side packings (cork
plates). and fit semi-circular rubber-packings in the grooves. To apply liquid packing to
corner intersections will prove very effective in preventing leakage.
Coat semi-circular rubber packings with oil on the surface so that oil pan edges will slide
easily on. Finally screw bolts (4 pieces each in front and rear) uniformly in order not to
strain packings.
