[. . . ] If they do, you will probably have to re-align them in a time consuming procedure described seperately. By tyingthe belt via a bungee or other cord to the hood or laying the belt towards the rear using a weight (wrench etc. . . ) to keep the belt tension, you can install the cam without having to re-align all of the lower sprockets. Remove bearing caps one and three, in that order. [. . . ] Check to see if the dot on the inside of the cam sprocket lines up with the upper edge of the camshaft drive belt inner cover (fig. If not, rotate cam slightly until it does. Slide camshaft belt over cam sprocket, taking care not to disturb the alignment of the camshaft sprocket. Re-install valve cover, tightening the nuts to 7 ft/lb. 10. Using a special spanner wrench (AST P/N 10. 012. 86400 or equiv. ), tighten the drive belt by rotating the tension pulley in the direction of the arrow (fig. The belt should feel tight when twisted 90 degrees with the thumb and forefinger, halfway between the camshaft and intermediate shaft pulleys. Tighten the pulley retaining nut to 33 ft/lb. 1 1. Turn crankshaft two complete revolutions and check belt tension, camshaft alignment, crankshaft alignment, and distributor alignment. If everything checks out, re-install distributor cap, timing belt cover, idle stabilizer valve assembly, brackets, crankcase ventilation hose assembly, and after-run control valve connector. 12. Start engine and run it at around 2000 RPM for twenty minutes. This is the crucial breakin period for a new cam. It is important that the cam has good oil pressure at this time!Once twenty minutes are up, you're ready to run. The blue coolant temperature sender must be disconnected when checking or adjusting ignition timing. fig. 5 A U T O T E C H Installation Instructions Drive Belt/ Pulley Alignment Procedure for G60 models Note: The following steps assume that the timing belt has slipped during camshaft installation or has otherwise lost tension below the intermediate shaft pulley. This procedure outlines how to get the motor back into time. 1. Loosen, but do not remove the lug nuts on the of passenger side road wheel. Jack up the passenger side of the car and support it with a jackstand. [. . . ] Since the drive belt is not installed, there may be piston to valve interference if you try to rotate the crankshaft too much. Check camshaft timing mark, make sure that the dot on the inside of the cam sprocket is lined up with the camshaft drive belt inner cover (fig 1). Install the camshaft drive belt by sliding it over the sprockets. [. . . ]
