Sourcing Guide
A product-focused guide to matching FAW Jiefang J6, JH6, J6P, J6L and J7 automatic slack adjusters by OE number, axle position, side and spline details.
FAW Jiefang J6 and JH6 trucks use several automatic slack adjuster designs across different axle positions and vehicle configurations. Similar external shapes do not guarantee interchangeability. A reliable quotation therefore starts with the OE number and continues with the installation side, axle position, spline or tooth count, arm geometry and clear photos of the removed part.
Our FAW Jiefang J6 / JH6 automatic slack adjuster range brings the currently documented references into one buyer-facing product page. The family also includes application clues for J6P, J6L, J7 and Hanwei vehicles, while each order remains subject to part-by-part confirmation.
In a drum brake system, the slack adjuster transfers movement from the brake chamber push rod to the camshaft. Its automatic mechanism is designed to help maintain the intended running clearance as the brake linings wear. Because this component works with a specific axle and brake layout, the correct arm length, offset, spline interface and left- or right-hand orientation matter.
A part that bolts into place but has the wrong geometry can affect push-rod angle or brake adjustment. For that reason, visual similarity should be treated as an initial clue, not final proof of fitment.
The current source record contains multiple FAW Jiefang references. The following examples are useful search and matching signals:
| OE / Reference | Documented Clue | Required Confirmation |
|---|---|---|
| 1058ZQES-3501050A / 1058ZQES-3501060A | Front wheel or front axle, light-truck direction | Vehicle model, side and spline or tooth count |
| 3501205AA2Q / 3501210AA2Q | Front axle, left and right references | Old-part marking, side and mounting layout |
| 3502205-A3F / 3502210-A3F | FAW Jiefang J6/JH6 family application signal | Axle position and spline details |
| 3503205-D6003 | Single documented catalog reference | Position, side and old-part photo |
| 3502205-Q5400 | FAW Jiefang brake adjuster reference | Complete number and physical comparison |
These references are not a universal interchange list. When the same vehicle model has more than one axle supplier or production configuration, the OE number and physical details take priority over a broad model name.
Place the removed slack adjuster on a plain surface and take one full front view, one rear view, one side view and one close photo of the marking. Add a ruler beside the arm if dimensions are not available. A separate straight-on photo of the spline opening is useful when the tooth count is uncertain. Do not crop away the arm end or side fittings.
Fleet workshops and distributors often purchase slack adjusters together with other truck brake parts, filters, bearings and chassis service items. Combining confirmed lines into one mixed shipment can simplify supplier coordination and make better use of container space. Each uncertain reference can remain marked for confirmation instead of being forced into an unverified match.
Send the OE number, FAW Jiefang model, chassis number when available, axle position, left or right side, required quantity and old-part photos. For a multi-item purchase, attach the full parts list so related brake and maintenance parts can be reviewed together.
Request a matching check and quotation for FAW Jiefang J6, JH6, J6P, J6L or J7 brake parts. Final selection will be confirmed against the supplied numbers and physical application details.
Use this guide to organize a clearer quote request instead of choosing from a short product list.
Part number, truck brand, model, engine model, chassis number and old-part photos help confirm the correct replacement before quotation.
Filters, brake parts, clutch parts, chassis parts, cab parts, bearings, sensors and assemblies can be checked together for one practical order.
Share quantity, packing preference and whether the order is for fleet repair, workshop use or distributor stock.
Send part numbers, truck models, chassis numbers, old-part photos or sample photos. We can help check multiple items and combine them into a practical export order.
