Camshaft gear backlash

: Refer to CAMSHAFT .

NOTE:

Camshaft gear backlash should be measured with the camshaft sprocket torqued to the camshaft. This will allow the intake camshaft to be held in place while backlash is measured on the exhaust camshaft gear.
The camshaft sprocket retaining tool base is made of steel and is a suitable location for attaching the suitable tool.

Installation of the remaining components is in the reverse order of removal.
