Glow Plug Replacement

Replace the glow plug(s) if they do not operate correctly.
(See Glow Plug Test in the Testing section of this
chapter.)
1. Remove the nut and lead wire.
2. Clean the area around the glow plug. This will prevent
dirt or other contamination from falling through the glow
plug hole into the cylinder.

Oil Pressure Switch Replacement

The engine is equipped with an oil pressure switch
(Fig. 45). This switch activates a lamp on the control
panel and a buzzer if the oil pressure drops below safe
levels during operation.
Pressure switch ON pressure: 0.5 kg/cm
Replace the switch if it is not operating correctly. Before
installing the switch put a small amount of Loctite #567
Thread Sealant (or equivalent) on the switch threads.
When installing the switch make sure the sealant does
not block the oil hole in the switch.
