	Removing
1	Remove flywheel		AR03.30-T-8002A
 	Disassemble/assemble
2	Drill into ring gear, pop it loose with a chisel and remove from flywheel
3	Clean contact surface of ring gear on flywheel
4	Measure outside dia. of contact surface of ring gear on flywheel	Outside dia. of contact surface of ring gear on flywheel	*BE03.30-N-1001-03E
5	Measure inside diameter of contact surface on new ring gear	 Calculate overlap between ring gear and flywheel: Outside diameter of the ring gear contact surface on flywheel minus the inside diameter of the bearing surface on ring gear. If measurement does not lie within the permissible overlap perform repair stage I of necessary.
		Outside  of contact surface for ring gear on flywheel	*BE03.30-N-1001-04E
		Inside diameter of contact surface for starter ring gear	*BE03.30-N-1002-04E
		Overlap between ring gear and flywheel	*BE03.30-N-1003-04E
6	Warm ring gear	 - Heat to a maximum of 230°C using a hot plate or heating oven. - Use temperature measuring chalk. - Grease ring gear with longlife grease.
		Starter ring gear - installation temperature	*BE03.30-N-1005-04E
		Temperature measuring chalk (white, thermochrome),
7	Drive ring gear onto flywheel.	 With the aid of a suitable drift.
8	Check axial runout of flywheel on ring gear	Ring gear flywheel permissible radial runout	*BE03.30-N-1005-04E
	Install
9	Install flywheel		AR03.30-T-8002A
