Here is some good, basic information about how to properly install connecting rods.
Step 1:
Apply the molybdenum base lubricant under the head of the bolt and on the threads.
Step 2:
With the bolts installed hand tight, install the gauge and zero the dial indicator. The stretch gauge must fit into the dimples on each end of the bolt.
Step 3:
Alternating from one side of the rod to the other, tighten the bolts.
Caution: Do not stamp connecting rod numbers on the rods. Instead, etch the numbers on the rods. Stamping will cause distort the roundness.
