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. 5). 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.
11. 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 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.
IMPORTANT! The blue coolant temperature sender must be disconnected when checking or adjusting ignition timing.
