SHACMAN Hande Axle Automatic Slack Adjuster DZ910034003

Automatic slack adjuster DZ910034003 is the brake stroke self-adjusting mechanism for SHACMAN trucks fitted with Hande (HanDe) drive axles. Mounted between the brake chamber pushrod and the camshaft lever, it maintains constant clearance between brake shoe and drum as the lining wears, so pushrod stroke stays within regulation range without manual re-adjustment. Excessive stroke is the most common cause of poor braking and failed inspections; replacing a worn slack adjuster restores correct stroke and even braking force across the axle.

This unit is brand-new old stock with the original laser marking intact on the cover plate: BOANDA / DZ910034003 / TET180615, plus casting number 3165 on the arm body. Spline and cam interfaces match the original Hande axle assembly, so replacement is direct.
