2) Checking of the overload clutch
General note
In the event of lead deposits and/or if slipping is suspected, it will be nec-
essary to check the overload clutch.
NOTE:
Slipping of overload clutch is apparent if at engine speed rise,
the propeller speed does not increase at the same rate.
NOTE:
The engine should be run for a short time just prior to the test,
otherwise there is the risk of the clutch “drying out“, resulting in
a higher torque.

Danger of damage to the engine suspension!
Depending on the engine installation (e.g. in the
case of extremely lightweight engine suspension),
the gearbox must be removed and the test carried out on a suitable moun-
ting attachment.
A specially prepared lever (e.g. length 3 m (9.9 ft.), see Fig.1) is fitted on
the propeller flange and the breakaway torque measured with a suitable
measuring tool.
