(j) Shut engine down.
NOTE:
On switching off the engine switch off ignition and withdraw the ignition key.
(k) Inspect rotary seal for leakage.
NOTE:
Due to the design of rotary seal, a certain amount of leakage is tolerated. If
the leakage is in excess of the limit rotary seal must be renewed.
Tolerated leakage:
For this check the engine must be operated until all temperatures have stabilized for a
period of 5 minutes. At that point shut down engine and ensure the ignition is switched off
and engine secured against unintentional operation. Coolant must not drip through leakage
bore, located at the base of the ignition housing, for a period of 1 minute after the engine
has been stopped.
In case this leakage test cannot be passed, the rotary seal must be renewed.
