5.2 Functions, Removal and Replacement of Glow Plug Screen
The screen is designed for uniform fuel supply to the CC. When replacing or
checking glow plug, it is necessary to check the screen for carbon deposits or clogging. If
there are carbon deposits, the screen should be replaced. In most cases removed screens
get damaged and are not re-usable. Install the screen using mandrel (Fig. 6) according to
Fig.5,all the way in (until the screen touches the evaporator in the combustion
chamber).Before installing replacement screen into the housing (bushing) clean the hole
"A" located on the cylindrical surface of the glow plug housing (bushing). The hole in the
screen should be positioned at ≈45° away from the fuel tube.
