Installing With Engine Installed
Timing chains, installingWith engine installed and cylinder head removed
- rotate engine until piston for cylinder 1 is in TDC position
- when piston is at TDC, a notch (arrow) should be visible on the intermediate shaft chain
If the notch is not visible
- turn crankshaft one complete revolution in direction of normal running rotation
NOTE: If the engine is rotated with the cylinder head removed, a second mechanic is required to guide the dual roller chain to prevent it from hanging up.
- position the camshaft in the cylinder head using the 3268 camshaft guide
- fill the 3 mm holes in the cylinder head gasket with AMV 188OO1O2 sealant
- install cylinder head assembling, Service and Repair
- insert rail on bearing bolt and bolt to cylinder head
- attach camshaft chain gear and dual roller chain to the shorter camshaft (cylinders 2, 4 and 6) using distributor connector and hand tighten
- attach camshaft chain gear and dual roller chain to the longer camshaft (cylinders 1, 3 and 5) and hand tighten
- remove camshaft 3268 camshaft guide
- tighten camshaft chain gear
- tightening torque: 100 Nm (74 ft. lb)
- use a 24mm wrench on hexes (arrows) to prevent camshaft rotation while torquing drive gears
CAUTION! DO NOT have the 3268 camshaft guide installed while tightening the camshaft gears.
- prepare cylinder head gasket for installation
- coat valve cover sealing surface with AMV 18800102 and insert sealing ring
- install front camshaft cover
- tighten chain tensioner
- rotate crankshaft two full turns in direction of engine rotation and stop when in cylinder 1 TDC position
CAUTION! DO NOT rotate the engine unless the chain tensioner is tightened; otherwise, the control chain will jump out.
- install and align 3268 camshaft guide onto cylinder head studs with both camshafts snugly positioned in the guide indentations (as shown)
- this alignment is only possible every 2nd engine revolution
