INSTRUCTION S 910-82725 Ring and Pinion Set up Tool 9 Inch Ford and 10 Bolt GM Options ©Speedway Motors, Inc. 2017 910-82725 RING AND PINION SET UP TOOL TO BEST UNDERSTAND - READ THROUGH ALL DIRECTIONS BEFORE BEGINNING 9 INCH FORD VERSION - 1. Write down the dimension that is stamped or etched on the end of the pinion. • If there is no dimension, contact the gear-set vendor or manufacturer. 2. Rest the Dial Indicator in the calibration fixture. 3. Adjust the Dial Indicator pointers so that the small hand points straight down to “1” on the inner dial (50 on the outer dial) and the large hand points straight up to “0” on the outer dial. • If you were to compare the needle positions to a clock, the clock would read 6 o’clock. • When reading the dial indicator, the needle movement counter-clockwise will indicate 1 plus the thousandths. A clock-wise movement will indicate 1 less the thousandths. • Verify that the housing is clean and free of any burrs or other irregularities that can affect the measurements. • It is best to have light grease (Vaseline) or oil on all components. 4. Install the pinion gear in the pinion support housing, with a crush sleeve or spacer installed and torque to proper specification. • A shim of .021 thousandths is typical of the shim thickness required for a proper set-up. You may wish to start with that amount. 5. Determine the correct end size of the measuring tool sliding locators to use in the carrier bearing races. 6. Install the carrier races (be certain that they are square in the housing) and the caps properly torqued. • You will have to have the measuring tool installed into the races before installing and torqueing the caps. • Use the springs to apply pressure to the sliding locators to hold them firmly in place in the races.
