SERVICE NOTICE

MERITOR AUTO SLACK ADJUSTERS

MERITOR USES A METHOD OF SPEC’ING THEIR AUTO SLACK ADJUSTERS OTHER THAN JUST THE CONVENTIONAL METHOD USED FOR SO MANY YEARS OF CAM SIZE AND # OF TEETH, CLEVIS SIZE AND THEN THE DISTANCE BETWEEN THE TWO-
IN AN EFFORT TO FURTHER INCREASE THE EFFECTIVENESS OF THEIR “ASA” AUTO SLACK ADJUSTERS, MERITOR CHANGES THE INTERNAL STRUCTURE OF THEIR SLACK ADJUSTERS TO MEET THE BRAKE TYPE (DISC or DRUM) AND THE SIZE OF THE AIR CHAMBER AND IDENTIFIES THOSE DIFFERENCES BY USING A COLOR CODED INTERNAL ACTUATOR PISTON ( BLACK, RED, YELLOW, GREEN OR BLUE)
IN CURRENT PRODUCTION THEY USE A “MYLAR” TAG ON THE SLACK WHICH HAS THE COLOR PRINTED ON IT, IN PREVIOUS PRODUCTION THEY USED A COLOR-CODED TIE WRAP FOR THE BOOT WHICH MATCHED THE PISTON COLOR.
SEEING AS DIFFERENT AIR CHAMBERS ARE USED FROM STEER TO DRIVE AXLES, YOU WILL MOST LIKELY SEE DIFFERENT SLACK ADJUSTERS USED FROM FRONT TO REAR, YOU WILL “NEVER” SEE SLACK ADJUSTER WITH DIFFERENT COLOR PISTONS USED ON THE SAME AXLE!
THE ATTACHED DOCUMENT “CAM BRAKES AND AUTO SLACKS” ON PAGE 13 AND 14 EXPLAINS THIS FURTHER AND “SLACK ADJ PARTS GUIDE” LISTS THE MERITOR PART NUMBERS AND THE PISTON COLOR WITH THE TYPE OF BRAKE AND AIR CHAMBER SIZE.
