The procedure involves positioning the number one piston at TDC on the exhaust stroke and removing the crankshaft damper/pulley, timing chain cover, and water pump as a unit. It is important to take note of various bolt types and locations. Following this, the secondary timing chain tensioners are removed, and camshaft sprockets are detached with caution to avoid damaging the camshafts. The idler sprocket, crankshaft sprocket, and timing chains are then removed as an assembly, requiring precision to maintain alignment. Inspection of components follows, checking for wear, chain stretch, and proper functioning of the tensioners and guides.
