Generalinstallation

Cylinder head removal is part of top end disassembly. See 3.10 TOP END DISASSEMBLY.

Clean and examine heads carefully before installation. If heads, values, guides or springs require service, see 3.11 CYLINDER HEAD SERVICE.

If heads have been serviced, remove cam journal caps and cams prior to cylinder head installation. The cams will be reinstalled after the heads have been installed and the head bolts torqued to specifications. See 3.22 INSTALLING AND TIMING THE CAMS.

Initial valve lash measurement and adjustment are to be completed as part of cylinder head service. However, after torqu-ing the cylinder head and installing the cam drive and timing the cams, valve lash should be measured and a valve lash calculation worksheet completed. See 1.22 VALVE LASH.
