DIESEL TIMING AND TACHOMETER
INSTRUMENT (SE-2783) OR (3005A)
The diesel timing and tachometer instrument (Figure 5)
is a solid state electronic instrument used to dynamically
measure fuel injection pump timing and automatic
advance in degrees. This instrument also reads engine
RPM from cranking to high idle speeds. The 14 mm
Split-Nut Transducer No. CT-4000-13 is used for 400
