Product Description

Does not require cutting down the top of the Wiseco piston!  For the Honda GX160, GX200, and 196cc clones. This rod measures 3.595" with .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 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 that is fed through a channel in the integrated dipper arm. Oil groove in the wrist pin bore that provides a reservoir of lubricant to the wrist pin. 

*The new Wiseco 11132PS piston is designed for the standard 2.678" bore on  GX160, GX200 and 196cc Clone engines, so with a fresh block and this new 6234 rod, you have a drop-in high performance piston/rod combination.  If your bore is larger, out-of-round, or the engine has already been run for a while with the stock bore piston, you will need to hone the block and use a larger piston such as the 11132P2 for a 2.682" bore (+.004")

Rod bolt torque: 170 in/lbs lubricated

Installation Instructions:

To install your ARC rod you will need a 12 point 1/4" socket and a QUALITY inch pound torque wrench. You will need an outside micrometer, dial bore gauge or plasti gauge, and oil.

Measure the crank pin diameter with the outside mic, it should measure 1.180" +/-.0005". Measure in several spots to insure roundness. If out of round more than .0005" it probably should be replaced. The crank pin finish should be smooth to the touch.

When disassembling the rod notice on the side of the rod 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.

Make sure the bearing and rod serrations are clean and install the bearings. Lubricate the rod bolt threads and hand tighten 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. If using plasti gauge you will have to install the rod on the crank and use in accordance the plasti gauge instructions.

The rod bore should measure 1.183 +/.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 recommendation.

Once clearance is set apply oil to 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.
