© 200324 2-3 General XE ENGINE LUBRICATION SYSTEM CF65/75/85 series 2 10 Pressure limiting valve lubricating system after the lubricating oil cooler. When the pressure set for the pressure limiting valve has been reached, the valve opens and any excess cooled lubricating oil will be discharged to the sump. Oil filter cartridge pressure relief valve (S2), fitted in this filter housing, opens if the pressure in the oil filter becomes too high as a result of fouling or cold lubricating oil. The lubricating oil then passes through the oil filter cartridge unfiltered. Main lubricating oil channel lubricating oil is supplied to the crankshaft main bearings (7) and via an oil channel in the crankshaft to the big-end bearings (10). From the main lubricating oil channel, lubricating oil is pumped through the first camshaft bearing (9) into the bored camshaft. At the end of the camshaft there is a sealing plug. From the lubricating oil channel in the camshaft, lubricating oil is supplied to the other camshaft bearings. Cylinder head lubricating oil channel runs through the cylinder heads to the second and fifth rocker seats (15). Depending on the model, the other rocker shafts, rockers, and bridge pieces are supplied with lubricating oil by the DEB or a lubricating oil strip (16). Timing gear crankshaft main bearing (7), another lubricating oil channel goes to the bored hub of the idler gear (8). From the bored hub, the lubricating oil reaches the idler gear. From the idler gear, the lubricating oil is supplied to the other gears. The fan drive (5) is lubricated through a bore in the cylinder block and a lubricating oil channel in the timing case. |
