The rod bolts should have a dimple in either end. Picture an outside micrometer with a dial indicator. Or the oposite of a ball gauge. A torque wrench is used as a guide othersie u ill not know when to start measuring the stretch. The rod bolt manufacturer should supply you with a info sheet on doing this and also what they recomend the stretch to be. To precisly meaure the oil clearance of your bearings you will need an outside micrometer and a ball gauge. The ACL bearing book or your engine manual should provide the correct oil clearance figure. To measure oil clearance 1: Install bearings and caps and torque down.(always use lube on bolts, not only to get more accurate figures but to lube the bolt and help it from galling) 2: measure crank journals with a mic. 3: Put the ball gauge between the mic when it is set on the journal size. Then zero the dial on the ball gauge dial indicator. 4: Use the ball gauge inside the torqued bearing cap and bearings. You should get a positive reading on the dial. If its negative u have lots of work to do. Telescopic gauges are only as good as there user. the same with any precise measureing tool. They do take a little more skill and experience to use accurately tho. these instruments are not your everyday worshop tool tho. [Report message to a moderator]
