  Q: How to Install a Camshaft on Dodge Viper?

  A:

  Before installing the camshaft, enhance the surfaces of the lobes and bearing journals with clean engine oil. Make sure to slide the camshaft into the engine block correctly, so the cam lobes don't harm the bearing surfaces. Secure the camshaft thrust plate in position and tighten the retaining screws to 12 Nm (106 in. lbs.) according to the suggested order. If the end play on the camshaft detected by a dial indicator is outside 0.0127 - 0.381 mm (0.005 - 0.015 in.) or exceeds 0.381 mm (0.015 in.), replace the thrust plate. Place the timing marks and dowel pin where they should be, using a straight edge to guide this and then bolt the Timing Chain and camshaft sprocket in place with the block of wood set on top of the engine to avoid movement. Put the camshaft phaser/sprocket assembly retaining bolt in and tighten it to 160 Nm (118 ft. lbs.). Join the camshaft phaser driveshaft and turn it in the opposite, roughly counterclockwise direction, until you check that it is aligned with the 12 O'clock Sidedirection. After that, add the camshaft drive plate/cover and seven outer bolts, tightening them with the block to 12 Nm (or 106 in. lbs.), following the correct sequence. Place and tighten the center retaining bolt for the camshaft drive plate/cover so that it shows 65 Nm (48 ft. lbs.). Replacing all tappets while working on the camshaft will keep the engine from being damaged. Now, mount the hydraulic tappets, the timing chain case cover, the oil pump pick-up tube with its new O-rings tightened to 28 Nm (248 in. lbs.), the Oil Pan gasket and oil pan and the finished placement is your cylinder heads.
