ENGINE DIAGNOSTIC TOOLS Section 4 OPERATING PROCEDURES NOTE: It is important that the following sequence of events be stricly adhered to. 1. 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 the line. 2. Install the 14 mm Split-Nut Transducer No. CT- 4000-13 as follows: a. 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 readings. b. 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 N•m (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 readings. 3. Check static timing (engine stopped). NOTE: Static timing must be checked before any timing checks are made with the timing light. 4. 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. 5. 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 Figure 7. 14 mm Split-Nut Transducer Installed UTDS* Model 100 Pump Shown 1.
