(1) Intellifast chip (2) Bar code Chip (1) is embedded in the threaded end of the bolt. The chip enables the Intellifast Ultrasonic Reader to measure the length of the loaded bolt and to calculate the load. Refer to the Special Instruction that is referenced above.Use of the Intellifast Ultrasonic Reader is not mandatory. However, the Intellifast Ultrasonic Reader accurately determines whether the connecting rod bolt has the proper load. The measurement reduces the risk that an installation error is not noticed.Bar code (2) included the serial number of the bolt and the original free length of the bolt.The new 369-7181 Bolt As is used with the same 205-0640 Nut that is used with the previous bolt.The new 369-7181 Bolt As uses the same tightening procedure as the former bolt. Follow the procedure that is described in the current engine Specifications manual. For additional information, refer to the Engine News that is referenced above.

(3) 369-7183 Heat Shrink Tube Prior to installation of the new 369-7181 Bolt As, inspect tube (3). The tube serves as an alignment sleeve for the bolt.
The tube must be firmly in place. The tube must not move under light finger pressure.
The whole surface of the tube must be smooth.
The tube must not extend into the fillet that is under the bolt head.If a problem is found with the tube, use the following replacement procedure.
Carefully cut the tube from the bolt.
Ensure that there is no damage to the shank of the bolt that was under the tube.
Clean the shank of the bolt with solvent in order to remove any oil or molylube.
Slide a new 369-7183 Heat Shrink Tube onto the bolt. Position the tube approximately 1.5 mm (0.059 inch) under the bolt head, away from the fillet that is under the bolt head.
Use a heat gun or place the bolt and tube in an oven at 135° 14°C (275° 25°F) for 10 minutes. The tube must shrink into place without any bumps or wrinkles.After the bolt cools, the tube must be firmly in place. The tube must not move under light finger pressure.Make sure that the surface of the tube is smooth all around. Make sure that the tube does not extend onto the fillet that is under the bolt headThe 369-7181 Bolt As may be tightened for a maximum of five times. The reuse includes retightening after checking the rod bore or bearing clearance.Do not reuse the 369-7181 Bolt As if there is any fretting on the shank or on the Ringed area. Do not reuse the bolt if the load measures more than 20 kN (4496 lb) when the bolt is checked with the Intellifast Ultrasonic Reader.An overloaded bolt can be detected by threading a new 205-0640 Nut onto the bolt by hand. If the threads are not damaged, the nut will easily reach the end of the bolt thread with light finger pressure. If the nut stops before reaching the end, do not reuse the bolt.An overloaded bolt
