ENGINE DIAGNOSTIC TOOLS
NOTE: It is important that the following sequence of
events be stricly adhered to.
Clean the area of the injection pump where the
transducer is to be installed (at #1 or #6 fuel
outlet). Do NOT install at the nozzle end of
Install the 14 mm Split-Nut Transducer No. CT-
4000-13 as follows:
Remove the fuel line connector nut (1,
Figure 7) and slide it up the pipe. Secure
the displaced nut with tape to prevent
bouncing of the nut and possible erratic
Install the 14 mm Split-Nut Transducer (2,
Figure 7) over the fuel line by slipping the
slotted portion of the transducer on the line
and tighten the Split-Nut Transducer to
allow slight fuel leakage at the split-nut
when the engine is started. Tighten the
split-nut only until leakage stops. Use of
this method will allow you to achieve the required torque
of 23.5 Nm (17.5 lb. ft).
NOTE: When applying or removing the Split-Nut
Transducer always make sure the short coaxial
(white) cable (3, Figure 7) is not caught up in the
lines. Pulling apart of the short white cable from the
transducer damages the ground, causing erratic
Check static timing (engine stopped).
NOTE: Static timing must be checked before any
timing checks are made with the timing light.
Mark the TDC dot on the crankshaft pulley and
the front cover pointer with white paint or similar
product so a clear reading can be obtained when
the strobe light is used.
Connect power leads to any 12 or 24 volt
negative ground electrical system. The power
leads are not color coded. Connect either lead
to the positive (+) side of the battery and the
other to a good ground. continued on next page
