Sourcing Guide
Confirm Shacman Delong L3000, M3000 and X3000 automatic slack adjusters by OE number, front or rear axle, installed side, spline detail and old-part photos.
A Shacman Delong automatic slack adjuster should be identified by its installed axle position before its outer shape is compared. Front-axle, rear-axle, left-side and right-side options can look close in a purchase image while using different references or mechanical arrangements. Keeping those details separate at the start makes a brake-parts request clearer and reduces the risk of mixing unlike positions.
The Shacman Delong automatic slack adjuster range includes documented options for L3000, M3000, X3000, X5000 and X6000 applications. The truck model is a useful search clue, but a correct order still needs the complete OE number, axle position, installed side, spline or tooth detail and clear photos of the removed unit.
Start a parts list with one line per removed adjuster. Mark the vehicle, front or rear axle, and the installed side before the unit leaves the truck. A workshop handling several brake jobs can otherwise place similar black forged adjusters in the same box and lose the position information that distinguishes them.
Take one wide photograph before removal. It should show the brake chamber pushrod, the slack adjuster and the camshaft area together. This installed view gives useful context for the arm direction and prevents an isolated bench photo from being interpreted as a complete fitment check.
The following reference codes are associated with these Shacman Delong applications. They are practical identifiers for a quotation request, not a universal interchange list. Confirm each line against the actual axle and old part.
| OE / Reference | Recorded Position Clue | What to Confirm |
|---|---|---|
| HD90009440983 | Front wheel / front axle | Complete marking, installed side, spline detail and arm layout. |
| HD90009440363 / HD90009440364 | Front axle, left-side and right-side references | Which side is required, spline or tooth count and old-part photo. |
| HD90129340257 / HD90129340258 | Rear axle | Rear-axle configuration, arm direction and center spline interface. |
| DZ9100340043 / DZ9100340044 | Rear axle | Complete number, installed orientation and pushrod-hole geometry. |
| HD95009440009 / HD90009340343 | Position and side to be confirmed | Axle position, side, spline detail and all visible markings. |
A short suffix can identify a different installed position. Do not replace a front-axle line with a rear-axle line, or a left-side line with a right-side line, solely because the housing color and arm profile appear similar. The OE number and physical installation details should lead the decision.
The center spline opening connects with the brake camshaft, while the forged arm connects with the brake chamber pushrod. A close, straight-on photo of the spline opening is useful when the tooth count is known or needs to be checked. Add full front, rear and side views so the arm length, offset and end-hole position can be compared with the old unit.
Do not estimate the spline count from an angled or dark photograph. Clean the opening carefully if needed, use a well-lit close-up, and provide the count only when it can be read confidently. When the count is uncertain, the old-part photo and axle information should remain part of the confirmation request.
Left and right references are easy to confuse after removal. Identify the side from the driver's position and label the image or purchase-list line accordingly. A pre-removal photo also shows whether the arm points toward or away from the brake chamber in its working position.
For a vehicle with several axles, include the axle nameplate image when available. It supports a clearer comparison when the truck model name covers more than one axle or brake configuration. The same approach is useful for fleet maintenance lists that include parts from several vehicles.
Keep confirmed and photo-pending brake parts on separate lines. Related truck brake parts, filters and maintenance items can be prepared in the same shipment, while every slack adjuster retains its own OE reference and axle information. This is useful for workshops and distributors that need several types of truck parts together rather than a single item only.
Send the OE reference, Shacman Delong model, front or rear axle position, installed side, quantity and clear old-part photos. Add the spline close-up and an installed view whenever possible. These details allow the requested adjuster to be reviewed against the actual brake arrangement before quotation.
Send a Shacman Delong brake parts inquiry with the part list and photos for matching support.
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.
