Disassembling the Crankcase

NOTE: The thrust plate, driving plate and flywheel must be removed before the engine is fastened to the engine support or assembly support.







1. Position toothed segment (special tool P210b) on the stud and undo the pan-head screws of the clutch thrust plate in several stages and in diametrically opposite sequence, in order to avoid deforming the thrust plate.







2. Fasten assembly fixture P238b with holder P140 onto the stud. Undo the the flywheel screws and remove the flywheel. Make sure that the pulse generator is not damaged.







3. Loosen belt pulley. For this purpose, a second person should counter with holding wrench 9548 at the same time. Do not use the hexagon-head bolt again.







4. Force vibration damper (belt pulley) off with the forcing screw 9285/1.

5. Unscrew the 18 hexagon nuts (M8) from the housing bolts.







6. Undo the hexagon nuts (a/f 17) of the left crankcase half (cylinder bank 1 - 3).







7. Loosen tension rod bolts from the outside to the inside.


NOTE: The tension rod bolts of bearing supports 2, 3, 4 and 5 -arrows- can be removed only after removing the crankcase half (cylinder bank 1 - 3).
