Figure 125. Installed the ARP balancer bolt. A torque wrench that reads up to 250 ft lbs had to be rented to do this job. The old bolt is torqued to 240 ft lbs then removed, then the ARP bolt and washer is coated with their ultra-torque lubricant, then the bolt is torqued to 235 ft lbs. The socket that fits this bolt is not a 27mm, even though that will likely work, the proper socket for this is a 12-point 1-1/16 socket.

Figure 126. Installed the water pump, also using ARP bolts. This pump came with the o-ring style gaskets, so no sealant was necessary, since the block surface is new and has no residual gasket or sealant on it. The bolts are torqued in a criss-cross pattern in two stages. The first stage is 11 ft lbs, and the second stage is 22 ft lbs.

Figure 128. All the belt drive accessories are installed. The power steering pump, bracket, and alternator are on here temporarily until they can be replaced/cleaned up. For now, they are installed to get wiring positions set and to make sure the belt will line up properly.
