Autotech 10.109.01.109 270 Sport Hydraulic Lifter Camshaft, Mk1, Mk2, Mk3 8V & Corrado G60 - Manual (Page 2)

6. Apply oil to the bearing surfaces, and a small amount of assembly lube to the lobes of
the new camshaft. Lay the camshaft in the head with the lobes for the number one cylin-
der facing up. Install bearing caps two and five, tightening down gradually and crosswise
until the camshaft is pushed completely into the bearing saddles. Install the remaining
bearing caps and torque all nuts to 15 ft/lb.
7. 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. 1). If not, rotate cam slightly until it does.
8. Re-install the valve cover and reinforcing strips, tightening the nuts to 7 ft/lb.
9. Slide camshaft drive belt over cam sprocket.
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. 4). The belt should feel
tight when twisted 90 degrees with the thumb and forefinger, halfway between the cam-
shaft and intermediate shaft pulleys. Tighten the pulley retaining nut to 33 ft/lb.
11. Caution! Before starting engine, turn crankshaft two complete revolutions and check
belt tension, camshaft alignment, crankshaft alignment, and distributor alignment. If every-
thing checks out, re-install distributor cap, timing belt cover, and idle stabilizer valve if so
equipped.
12. Start engine and run it at around 2000 RPM for twenty minutes. This is the crucial
break-in 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.
