• Peeling
Fig. 8-13 Damper - Check
• If the damper is defective, contact your
SME dealer
"CONTACT LIST" (→ Page
8).
Damper Temperature - Check
To ensure the proper function of damper, heat must
be dissipated from its surface to prevent excessive
heating.
Be sure to obey the instructions below:
• Make sure the temperature of the damper
outside surface does not exceed the temperature
described in the following table when operating
the engine at the rated power output.
• When installing a protective cover to the damper,
provide adequate ventilation so that the damper
temperature does not exceed the temperature
listed in the table below.
Install a protective cover which can
dissipate heat.
* Otherwise, the damper could be enclosed and
degenerated due to poor heat dissipation and
ventilation, and which may cause breakage of
the crankshaft.
