Inspect connecting rod bolts at each service of the connecting rod bearings. There should be no fretting on the shank, knurled or annular ring area (2) of the connecting rod bolt. Ensure that the connecting rod bolt meets the guidelines for the reusable parts. Do not reuse the connecting rod nuts. Prior to installation of the new 467-0537 Bolt As, inspect heat shrink tube (1). The tube serves as an alignment sleeve for the bolts.
The heat shrink tube must be firmly in place and 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 heat shrink 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.
Install 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. Verify that the tube does not extend onto the fillet that is under the bolt head. The 467-0537 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 connecting rod nuts. 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. Tightening Procedure for Connecting Rod Bolts

(1) 4W-8344 Retainer
Before the bolts are installed into the connecting rod, clean retainers (1). Clean the seats for the retainers on the connecting rod and the bolt heads. The parts must be clean and dry.
Inspect each bolt for debris, nicks, and for damage from shipping.
Assemble the retainers and the bolts into the connecting rod as shown in Illustration 2.
After the bolts have been installed, lubricate the threads of the bolts, threads of the nuts, and the seats for the nuts on the connecting rod with a heavy coat of 334-0519 Grease. Note: This torque procedure was developed with 334-0519 Grease. The use of any other lubricant may result in an incorrect torque value and in subsequent failure of the connecting rod bolt.
While holding the rod cap tight against the connecting rod, ensure that the connecting
