The Laser 6084 is a 3 piece kit designed to allow a Dial Test Indicator (DTi) gauge to be mounted securely in position against the brake disc to measure disc warp. This kit is ideal for the measurement of run-out on almost any rotating component including: Brake disc run-out Drive flange run-out and end float Differential drive flange run-out End float propeller shaft run-out Flywheel run-out Crankshaft end float Crankshaft and bearing ovality Lathe/turning machine run-out and ovality. The 6084 can also be used on motorcycles. The simple locking pliers allow the tool to be locked to any handy suspension bracket or component, and its unique design allows the DTi gauge to be rigidly mounted in almost any position.
