Begin installation by mounting the Crankshaft sprocket before adding prelube from sealers, adhesives, and lubricants to the sprocket thrust surface using the right part number. Before completing dampener installation tighten the bolts to 21 n.m (15 lb ft). Begin by mounting the Timing Chain onto the camshaft gear and then grip the camshaft sprocket with the chain dangling below. Finally, attach the chain between the camshaft and Crankshaft gears.
