not lined up, loosen the fan bracket
mounting bolts, align the sheaves, and
retighten the mounting bolts.
11. Check the vacuum fan belt tension. There
should be 0.18 in (5 mm) deflection from a
force of 8 lb (4 kg) applied at belt span
midpoint. To adjust tension, loosen the fan
bracket mounting bolts, slide the fan bracket
forward to loosen or backward to tighten the
belt, and retighten the mounting bolts.
Recheck the sheave alignment.
12. Check the alignment of the engine jackshaft
sheave with the engine sheave. If they are
not lined up, loosen the engine mounting
bolts, align the sheaves, and retighten the
bolts. The engine jackshaft sheave may also
be moved by loosening the sheave clamp
bushing.
13. Check the engine belt tension. There should
be 0.16 in (4 mm) deflection from a force of
12 lb (5 kg) applied at belt span midpoint. To
