Engine lubrication system for all models except GLA (Escort 3)

The lubrication system of engines of all models except GLA includes an oil pump 1 (Fig. 2.70) with a pressure reducing valve, an oil filter 9 and an emergency oil pressure sensor 13, and for engines with injection since 1982 an oil cooler 3 was installed between the oil filter and the cylinder block (fig. 2.5), connected to the engine cooling system.



The gear oil pump with internal trochoidal engagement gears is installed on the front end of the cylinder block. The pump drive gear is installed on the front end of the crankshaft. Oil pressure at its temperature of 80°C: at a crankshaft rotation speed of 750 rpm - 1.0 kgf/cm²; at a crankshaft speed of 2000 rpm — 2.8 kgf/cm². Replaceable, full-pan oil filter of the Motorcraft Super EFL 134 brand. The emergency oil pressure sensor turns on the red signal lamp on the instrument panel at an oil pressure of 0.3-0.5 kgf/cm².



On the XR3 model produced since July 1982, the amount of oil added to the system has been reduced to 3.5 l with a filter change and to 3.25 l without a filter change. Since December 1982, the same amount of oil has been added to other models. If the engine has a green oil dipstick, the engine is equipped with an emergency oil level sensor; if the dipstick is white, such a sensor is not installed. For engines without such dipsticks, the amount of oil in the system has remained the same (Table 1.8). Since April 1983, for engines with injection, the use of Mobil 1, Veedol-Huile synthetique, Castrol TXT and Castrol formule RS synthetic oils has been permitted with replacement every 10,000 km.

Removing and installing the oil pan

Disconnect the negative cable from the battery and drain the oil from the lubrication system. Disconnect the wires from the starter and remove it. unscrew the three mounting bolts. Remove the clutch housing cover. Unscrew the oil pan mounting bolts and. move it to the side with a screwdriver, and remove. Before installing the oil pan, thoroughly clean its mating surfaces. Install new rubber seals in the annular grooves of the rear bearing and oil pump housing, and secure the cork gasket to the cylinder block using plastic grease. Install the oil pan and tighten the mounting bolts in two steps to a torque of 0.8-1.1 kgf·m. Screw in the drain plug. Install the clutch housing cover. Install the starter and connect the electrical wires. Fill the lubrication system with oil and connect the negative cable to the battery.

Removing and installing the oil pump

Drain the oil from the lubrication system. Remove the toothed belt cover and the toothed belt. Remove the crankshaft toothed pulley and oil pan. Remove the oil pump. Clean the oil pan and oil receiver before installation. Install the oil pump in the reverse order of removal.
