	Removing, installing
1	Remove camshaft housing		AR05.20-P-6995HA
2	Attach graduated scale to vibration damper	Attach graduated scale in pin at vibration damper
	Graduated scale for vibration damper		WF58.50-P-0330-03A
3	Install assembly tool for valves at cylinder head	To do this, screw retaining fork (14) (M7x60) with hinged fork (19) into hole of camshaft housing attachment at cylinder head
4	Rotate piston of cylinder to be tested to TDC	Rotage engine at crankshaft; hold timing chain (25) up for this step so that it does not jam. Piston at "TDC" in the case of marking index on vibration of Engine 604 TDC cylinders 1 and 4, 180° cylinders 2 and 3 Engine 605 TDC cylinder 1, 72° cylinder 2, 144° cylinder 4, 216° cylinder 5, 288° cylinder 3 Engine 606 TDC cylinders 1 and 6 120° cylinders 2 and 4 240° cylinders 3 and 5 Installation: ensure that the colored markings on timing chain and camshaft sprocket are again aligned after installing the camshafts.
5	Install retaining lock (3) for crankshaft / ring gear	According to TDC setting of cylinder to be tested to prevent crankshaft or piston being turned on Use bolts (4) M6x90 otherwise the threads in the rear end cover will be damaged	AR03.30-P-5000HA
6	Connect cylinder leaktightness tester (01) to the cylinder to be tested	Pressurize cylinder to approx. 5 bar	AR01.00-P-1300-01HA

		Connection M22x1.5 mm / R1/4" for injection nozzle	*WH58.30-Z-1002-05A
7	Remove valve springs (22)	Attach detent depresser (5) with lever handle and thrust piece (7) into hinged bearing (19) for this step. Align thrust piece (7) vertically to valve spring (22). Compress valve spring (22) and remove valve collets (20) with magnetic pin, magnetic finger or tweezers. Valves must not strike the piston crown
		Magnetic pin (02)	Fig 7
		Magnetic finger	Figure
		Tweezers	*WH58.30-Z-1040-02A
8	Remove valve stem seals (23) with pliers	Inspect valve stems for burrs, deburr if necessary. Inspect bottom valve spring retainer (24) for pitting, replace if necessary.
		Pliers Installation: oil valve stem seals. Press on valve stem seals with assembly drift by hand	Figure
