ENGINE LUBRICATION SYSTEM DESCRIPTION OF LUBRICATION SYSTEM ——The rotor oil pump (1) at the front end of the crankshaft sucks oil out of the oil pan (3) by oil strainer (2) and pressurizes oil, and then the pressurized oil will enter the full-flow oil filter through the auxiliary oil passage (4) at the left side of the cylinder(view from the front). A relief valve (6) is set up inside the oil pump to control the pressure at the main oil passage.
PAGE 3
——Hydraulic jib gets oil through the oil passage through which the oil tank at the camshaft supplies oil to the cylinder cap. ——The interface between valve rocker and hydraulic jib is lubricated by oil through the oil hole in hydraulic jib. ——Rocker seat is lubricated by oil through cylinder cap oil passage. The interface between valve small end and rocker is lubricated through splashes. OIL PAN Disassembly: ——To unscrew the oil-tapping bolt and empty the pan. ——To unscrew 18 M6X20 bolts.
PAGE 4
Assembly: ——To spread Letai 598 seal glue or GY409 anaerobic glue on the connecting areas between cylinder oil pan flange and oil pump body and rear oil seal support. A From crankcase to oil pump body B From crankcase to rear oil seal support ——To put the new rubber gasket on the cylinder body, placing both ends of the gasket into the rear oil seal support and oil pump rut. ——To install oil pan, placing both ends of the gasket into oil pan rut.
PAGE 5
OIL FILLING — — To fill the engine with 3.1 ± 0.15L of oil (SAE10W/30SF grade, or SAE5W/30SJ grade at temperature lower than -18℃) ——The oil surface shall be between “max” and “min” on the dipstick. OIL STRAINER ASSEMBLY Disassembly: ——To unscrew the locknut of the oil strainer support and take out the nut and gasket. ——To unscrew and take out the support bolt. ——To unscrew oil strainer flange bolts (two) and take out two gasket bolts with spring.
PAGE 6
OIL PUMP AND FRONT OIL SEAL Disassembly: ——To unscrew and take out six M6X30 hexagon flange bolts. ——To take out oil pump and front oil seal assembly. ——To use a screwdriver or chisel to take out the crankshaft front oil seal and pay attention not to touch or damage the front oil seal. ——To take out 7 M6 bolts (as indicated by the arrows in the figure). ——To demount the oil pump cover plate.

——To take out the internal and external rotors. ——To check out the clearance between the pump external rotor and pump body. The oil pump external rotor shall have a clearance of 0.06-0.19mm with oil pump body. ——To check out the radial clearance between oil pump internal rotor and external rotor. The clearance between internal and external rotors shall be 0.05-0.18mm. B-7 PDF created with pdfFactory Pro trial version www.pdffactory.
PAGE 8
——To check out the rotor end clearance. The rotor end clearance shall be 0.014-0.100mm. ——To unscrew and take out the horizontal internal hexagon bolts (small ones). ——To take out relive vale spring and relief valve ball. ——To check out the spring load and free length. The free length is 46mm; The spring load is 32.8N±2N at 29mm; The installation length of relief valve spring is 38.5mm. ——Bad relief vale spring, if any, has to be changed.

Assembly: ——To place external and internal rotors into the oil pump body, making sure the installation marks on the external and internal rotors are upward. ——To place the oil pump cover plate onto the oil pump, screw up the 7 bolts to 7-10N.m. ——To install the relief valve and relief spring into the oil pump hole. ——To screw the bolt into the oil pump body to 20-25N.m. ——To use oil to adhibit the new oil pump gasket to the front end of the cylinder body.
PAGE 10
——To remove the thing plastic strip. OIL FILTER AND OIL PRESSURE SENSOR Disassembly: ——To demount the oil filter by rotating the filter counterclockwise. ——To remove the oil pressure sensor. Assembly: ——To spread engine lubrication oil onto the oil filter gasket and screw it up to the fitting to 12-17N.m., or screw the oil filter manually and screw more 3/4-1 round when the rudder gasket reaches the cylinder. 8.0-25.0N.M Fastening Torque Of 8.0-25.0N.
