We used the” torque and angle” method to install our ARP connecting rod bolts. In this method, the connecting rod bolt is first cleaned and then lubricated with specific ARP bolt lubricant. It's important to use the specific lubricant supplied with the bolts as different lubricants can reduce or increase friction and alter the amount of torque that the bolt requires to overcome the friction. Once the bolt is lubed, it is torqued to the amount specified by ARP and after, rotated a certain increment of degrees. After installing the connecting rod bolt using the “torque and angle” method, we used a stretch gauge to insure that the bolt was installed with the correct amount of preload. |
