Anchor Pin Adjustment

  1. Loosen anchor pin lock nut one-half turn.
    NOTE: On front wheels, it is necessary to loosen backing plate upper mounting stud.

    Tap anchor pin up, then down to bottom of slot. Turn star adjuster to expand brake shoes until drum cannot be turned in direction of forward rotation. Tap anchor upward lightly; drum should be free and rotate easily. Retighten star adjuster and repeat tapping anchor nut until drum cannot be rotated (this will cause brake shoes to centralize the anchor). Loosen star wheel until a.015" feeler gauge can be inserted between bottom of secondary lining and drum. Rotate drum forward until feeler is wedged between secondary shoe and drum, then turn drum back until feeler is at bottom of lining. This clearance should be.015".

  2. If clearance is not as specified, adjust star wheel to obtain proper clearance. Also check clearance between drum and top end of secondary lining. This clearance should be.010". If clearance is not correct, tap anchor pin up if more than specified, or down if less than specified. A.010" feeler gauge should clear all around lining, including primary lining.
    CAUTION: Do not attempt to set.010" or.015" clearance at primary shoe.

    Tighten front anchor lock nut and backing plate upper mounting stud to 80-100 ft. lbs. Tighten rear anchor lock nut to 100-120 ft. lbs. Recheck lining-to-drum clearance.
