ARC Rod Installation Instructions

Tools Needed:

• 12-point 1/4" socket
• Quality inch-pound torque wrench
• Outside micrometer
• Dial bore gauge or plastic gauge
• Lubricating oil

Step 1: Measure Crankpin Diameter

Using the outside micrometer, carefully measure the crankpin diameter in several locations to check for roundness and size. The diameter should be 1.188" ± 0.0005".

• If out of round by more than 0.0005", consider replacing the crankshaft.
• The crankpin surface should be smooth to the touch, free of scoring or roughness.

Step 2: Identify Rod Orientation

When disassembling the rod, note the two dots located next to the separation point between the beam and cap on the side with the part number. These marks ensure proper alignment during reassembly.

• The side with the engraved part number always faces the side cover of the engine.

Step 3: Prepare Rod and Bearings

• Thoroughly clean the rod, bearing surfaces, and serrations to remove any debris or contaminants.
• Install the rod bearings carefully, ensuring they seat fully.
• Lubricate the rod bolt threads with oil to ensure accurate torque readings.

Step 4: Initial Bolt Tightening

• Hand tighten the rod bolts using the 12-point socket.
• Using the torque wrench, tighten the bolts to 60 inch-pounds.
• Then, alternate tightening each bolt in increments of 20 inch-pounds until you reach 150 inch-pounds.

Step 5: Measure Bearing Clearance

• Using a dial bore gauge, measure the bore diameter opposite the parting lines.
• If using a plastic gauge, install the rod on the crankshaft and follow the plastic gauge instructions carefully.
• Target bore measurement: 1.191" ± 0.0005".
• Ideal bearing clearance: approximately 0.003" (acceptable range: 0.0025" to 0.0035").

If your clearance falls outside this range, please contact support at 800-521-3560 for guidance.

Step 6: Final Assembly

• Apply oil generously to the rod bearings, crankshaft journal, and wrist pin.
• Reinstall the rod and torque the bolts to the final specification of 170 inch-pounds.

Important Note:

Improper torque on rod bolts is one of the most common causes of rod failure. Always follow the torque specifications carefully to ensure engine reliability and performance.
