This rod measures 3.595" center to center for a 1.188" crankpin with a .490" wrist pin and is designed to be used with aftermarket high-performance pistons. *Bearings and custom-designed high tensile strength bolts are included. All of our rods are CNC machined from aircraft-grade domestic 7075 T-651 aluminum. Our OHV rods are designed to utilize the higher compression ratios and high RPMs of racing OHV engines. Key Features Include: Oil groove in the crank bore fed through the integrated dipper arm channel. Oil groove in the wrist pin bore provides a reservoir of lubricant to the wrist pin.
Rod bolt torque: 170 in/lbs lubricated

You will need a 12 point 1/4" socket and a QUALITY inch-pound torque wrench to install your ARC rod. You will need an outside micrometer, dial bore gauge or plasti-gauge, and oil.
Measure the crankpin diameter with the outside mic; it should measure 1.188" +/-.0005". Measure in several spots to ensure roundness. If out of round more than .0005" it probably should be replaced. The crankpin finish should be smooth to the touch.
When disassembling the rod, notice on the rod's side with the part number there are two dots next to the separation point of the beam and cap. These dots help to re-orientate the cap and beam when assembled. The side of the rod with the part number engraved will always face the side cover side.
Ensure the bearing and rod serrations are clean and install the bearings. Lubricate the rod bolt threads and hand tightens the bolts. Using the torque wrench, tighten the bolts to 60" lbs. Alternate each side to increase the torque by 20" lbs at a time until you reach 150" lbs. Then loosen the bolts and repeat the torque process. this helps seat the rod bearing, especially on a new rod. Measure the bore with your dial bore gauge opposite the parting lines. Using plasti-gauge, you will have to install the rod on the crank and use it per the plasti-gauge instructions.
The rod bore should measure 1.191 +/.0005". With plasti-gauge, you are looking for about .003" clearance. From .0025-.0035" clearance is acceptable. Anything outside that dimension, please call 800-521-3560 for a recommendation.
Once clearance is set, apply oil to the rod, crank, and wrist pin and install this time torque to 170" lbs.
Improperly torquing rod bolts is one of the most common causes of rod failure.
