Alfa Romeo Camshaft Timing and Installation
Included in this document is a cam-timing template. Follow the instructions for the template to check the timing marks on the front camshaft bearing caps. If necessary, scribe new timing marks onto the cam caps.
To install the camshafts, start by putting the engine to Top Dead Center (TDC) - #1 cylinder. TDC #1 is when the #1 cylinder piston is at the top of it’s stroke, and the #1 camshaft lobes are pointing to the outside of the engine (intake lobe pointing toward the intake manifold, exhaust lobe to the exhaust manifold). TDC is the “P” mark on the crankshaft pulley. Make sure the timing pointer on your engine is really pointing to TDC. It is best to use a TDC gauge to check this. Adjust the pointer if necessary. Remove the original camshafts following the instructions in your Alfa shop manual. Transfer the two camshaft sprockets to the new cams to be installed. Inspect the cam followers for wear. If there are any irregularities or crazing on the tappet surface (where the lobe hits), replace the tappets.
