Meritor-Type Automatic Slack Adjuster - Unhanded 1-1/2in-28 x 5.5in Arm - E11401 R801070 3947646 139.2831

Out-of-adjustment brakes are a top CSA violation, and the usual culprit is a slack adjuster that has quit taking up lining wear. This Meritor-Type Automatic Slack Adjuster distributed by FleetPro Parts & Tires converts brake chamber pushrod stroke into S-cam rotation and then self-adjusts brake shoe clearance, so the long pushrod stroke that fails an inspection never gets a chance to build. It is the straight replacement for a worn or seized unit, and because it is unhanded, one part number covers both ends of the axle. Manufactured by Automann to Fleet Standard specifications, it is stocked heavily right here in our Hanover Park, Illinois warehouse for lightning-fast shipping to fleets, diesel repair shops, and owner-operators nationwide.

Stroke Under Control: The Unhanded Meritor-Type Slack Adjuster Advantage

The three dimensions that decide fitment are all spelled out on this unit: a 1-1/2in x 28 spline bore that indexes on the camshaft, a 5-1/2in arm that sets the leverage the axle was engineered around, and a 5/8in-18 clevis that threads onto the chamber pushrod. The 179.YK5005 Clevis Kit is included, so the pushrod joint goes back together on new hardware rather than a clevis already worn oval by a season of stroke - slop at that connection reads as stroke the adjuster cannot recover.

Unhanded construction is the practical win on the shelf. There is no left-hand and right-hand version to stock, mix up, or run out of at six in the morning: the same 7 lbs unit fits either side, which is exactly what you want when the right move is to replace in axle pairs so both wheel ends adjust and apply together. Changing only the failed side leaves the truck braking unevenly, and uneven braking is what eats the linings on the good side while the driver wonders why the pull came back.
