© 200505 3-3 Checking and adjusting CE ENGINE ΛΦ45/55 series 2 5 3.2 CHECKING AND ADJUSTING TIMING GEAR Note: The engine is fitted with gears on either side. The gears at the vibration damper end only drive the oil pump. These gears have no marks and may be fitted in any position. The timing gear wheels on the flywheel side drive the camshaft, air compressor and fuel pump. Only the camshaft gear and the crankshaft gear have marks which must be aligned. The other gears may be fitted randomly. 1. Remove the engine encapsulation panels. 2. Remove the gearbox. 3. Remove the flywheel. See "Removing and installing". 4. Remove the flywheel housing. See "Removing and installing". Note: When the engine crankshaft or camshaft is turned separately, the pistons and valves may touch each other. 5. Use an open-end spanner on the fan shaft to turn the crankshaft clockwise, as seen from the vibration damper end, until the marks in the crankshaft gear and camshaft gear match. The crankshaft gear has a punched hole in the tooth which has to fall into the tooth depth of the camshaft gear marked with a punched hole. M201318 |
