1 Ring gear

2 Flywheel

A Bore (for mounting clutch pressure plate)

B Outside diameter (of ring gear (1) contact surface on flywheel (2))

	Removing
1	Remove flywheel (2)		AR03.30-G-8002MT
	Disassemble
2	Center drill ring gear (1), unclip using a chisel and remove from flywheel (2)
3	Clean ring gear (1) contact surface on flywheel (2)
	Measure
4	Outside diameter (B) of ring gear (1) contact surface on flywheel (2)	 If value given in table is not met then the flywheel (2) must be resurfaced to repair stage I. Replace flywheel (2) if necessary.	*BE03.30-N-1001-04L
5	Measure inside diameter of contact surface on new ring gear (1)	 Calculate overlap between ring gear (1) and flywheel (2): Outside diameter (B) on flywheel (2) minus inside diameter of ring gear (1).	*BE03.30-N-1002-04L
		 If the calculated measured value is not within the permissible overlap then use ring gear (1) of repair stage I if necessary.	*BE03.30-N-1003-04L
	Assemble
 Danger!	Risk of injury to skin and eyes caused by handling hot or glowing objects.	Wear safety gloves, protective clothing and safety glasses, if necessary.	AS00.00-Z-0002-01A
6	Warm up ring gear (1)	 Warm up using a heating plate or oven to the maximum installation temperature.	*BE03.30-N-1005-04L
7	Press ring gear (1) onto the flywheel (2) as far as the contact surface	 With the aid of a suitable drift.
8	Check axial runout of flywheel (2) on ring gear (1)		*BE03.30-N-1005-04L
9	Drill holes (A) for mounting the clutch pressure plate in the ring gear (1) and tap thread (standard M10)
	Install
10	Install flywheel (2)		AR03.30-G-8002MT
