Modification notes

1.3.96

Timing chain with press-fitted center plate replaces timing chain with moving center plate

Refer to step 4

	Removing, installing
1.1	Remove viscous fan coupling	Engine 604 in models 202, 210	AR20.40-P-5660HA
		Engines 605, 606 in models 124, 210 Engine 605 in model 202	AR20.40-P-5660HB
		Engine 606.964 in model 463	AR20.40-P-5660GG
2	Remove chain tensioner (3)	Replace seal of chain tensioner.	AR05.10-P-7800HA
3	Removing, installing cylinder head cover		AR01.20-P-5014HA
4	Separate timing chain (4, 5) and rivet	It is essential to remove the connecting link (04). It is only an assembly aid and is not suitable for engine operation.	AR05.10-P-7601-03A
