Precision Rebuilding. Restore Performance.
The AMC-SCHOU CRA 2 is a precision measuring and correction tool designed for the inspection of bend, twist, and offset in connecting rods up to 460 mm (18 in.) in length. Any detected irregularities can be corrected using the bending and twisting tools supplied as standard. The system is supplied complete and requires no additional tools or instruments.

Features
BEND INSPECTION
When checking for bend with the piston mounted on the connecting rod, the rod is placed on the arbor with the lower part of the piston resting firmly against the stop. The connecting rod is then removed and repositioned with the opposite side of the piston against the stop. A second reading is taken from the top of the piston. By comparing the two readings, the amount of bend can be determined.
CONNECTING ROD BEND CHECK
The illustration shows a connecting rod being checked for bend. Measurement is performed by checking the piston pin at both ends while moving the arbor.
TWIST INSPECTION
Twist is checked using the test bar. Both ends of the piston pin are pressed firmly against the test bar, and the amount of twist is measured with a feeler gauge.
