Fan Drive and Blade
Fan Blade Clearance: Around the fan shroud, the recom-
mended distance is 1 in. (25 mm) from front edge of any fan
blade-to-radiator side member. Minimum clearance is 3/4 in.
(19 mm).
• Rear edge of any blade must be no closer than 3/8 in.
(9 mm) to the nearest engine component. If this cannot
be obtained, the fan spacer or fan is not correct.
• The leading edge of any fan blade must be 1 in. (25 mm)
from the inside edge of the shroud.
Exhaust System
The exhaust system is part of the noise control system. Peri-
odically check the exhaust for wear and loose or missing
parts. For details, see “Noise and Emission Control” on
page 220.
