The mounting height of the DSS sensors must be measured as follows to determine the final position (top or bottom hole mounting position):
Step 1: Remove the big nut (SW36) (1).
Step 2: Remove the lock washer (2) and brass “V’ backstop (3).
Step 3: Put the screw stud (4) below the rail foot.
Step 4: The rail foot claw is clamped between “V” sections. Place the brass “V” backstop (3) and lock washer (2) and big nut (1) back on the screw stud.
Step 5: Tighten big nut (1) using a torque wrench between 88 to 110-foot-lbs of torque.
Step 6: Put the adapter plate (5) onto the SSK 6 claw; take care of the correct plate position.
Step 7: Fix the adapter plate (5) with 2 lock washers (6) and 2 hexagonal screws M12x25 mm (7) at the center of the SSK 6 claw. The final fastening position will come later during the adjusting procedure.
Step 8: Tighten the fastening screws (7) with 36 to 44 foot lbs of torque.

Step 9: Put the proper mounting plate spacers (8) onto the brass foot of the wheel sensor (DSS).
Step 10: At this time loosely fasten the wheel sensor (DSS) using 2 washers (9), 2 lock washers (10) and 2 hexagonal screws (11) M12x25 mm onto the adapter plate (5).
Step 11: Make sure that the cable is routed through the guide hole in the SSK 6 claw.
Step 12: Slide the wheel sensor on the adapter plate until the wheel sensor (DSS) contacts the web of the rail via the mounting plates (8). At this point it must still be possible to slide the wheel sensor (DSS) on the mounting plate if necessary for final adjustments so just slightly snug the bolts holding the wheel sensor on the plate.
Step 13: For the height adjustment of the sensor, loosen the hexagonal nuts (SW19) (12) on the brass slide bracket. The adjusted dimension can be changed by using the hexagon threaded stud (Inbus S 5) (13) to either lower or raise the wheel sensor attached to the plate to position the wheel sensor to the correct height “Y” value required. Use a 5mm Allen wrench in the hexagon stud to make this adjustment. Refer to the adjustment procedures.
Note: For 141lb rail types add a 10mm spacer or 10mm brass washers underneath the wheel sensor between the wheel sensor bottom and SSK6 mounting plate. The spacer must allow for the mounting bolts to pass through them to keep them locked in place and firmly against the mounting plate.
Note: It is not possible to use the 2N59-1R-400RE-40 wheel sensor with the SSK 6 clamp due to the fact that the off-rail function will not work.
