T-1158 - ROD BOLT STRETCH GAUGE. PROFESSIONAL .0005 ACCURACY

A windowed block is usually caused by "kicking the rods". This very expensive failure is commonly the result of a connecting rod bolt failure. A bolt that has stretched more than .007 is getting near the end of its life. But how does one check the stretch on these bolts? Very quickly with the Rod Bolt Stretch Gauge.

One simply inserts the rod bolt into the bottom of the Stretch Checker and records the reading on the gauge which has an Accuracy reading of .0005". A complete set of 16 bolts can be checked in less than 60 seconds. Might just be the best minute you invested in your engine assembly. (Video)
