Basic product parameters
Part OE Number: WG9100340056 (Left)
Right-hand accessory: WG9100340057
Product Name: Rear Axle Braking Clearance Automatic Adjustment Arm Assembly(Left)
Key specifications: 19-tooth standardinternal spline. Mounting location: left brakeon the rear axle. Compatible models:Sinotruk Howo T7H/T5G, Shandeka C7H,older Steyr models, Haohan series tractorsdump trucks, construction waste trucks.
Surface process: High-temperature forging + color zinc plating double-layer rust prevention
Five Core Product Advantages
1.Original factory 1:1 mold opening non-destructive direct installation without modification
Strictly follow the original factory drawings forforging and pressing, 19-tooth standard internalsplines, and the fixed mounting holes fully matchthe rear axle brake camshaft. The repair shopdisassembles and assembles without grinding,reaming, and replacement of old parts in one step.
2. Fully automatic clearance compensation, safer driving braking
To install a precision ratchet automaticadjustment structure, automatically tighten theclearance after brake pad wear, stabilize thebrake pedal stroke, prevent vehicle softness,one-sided misalignment, braking delays, andreduce the risk of long downhill driving.
3. Thickened forging body, heavy-duty vibration, and less prone to fracture
The integrated forged steel is produced as an integralunit, with no splicing of thin materials, construction sites,and long-distance heavy-load and bumpy workingconditions, offering resistance to impact and deformation,
with a service life more than twice that of casting models.
4. Double-layer color zinc plating prevents rusting dueto mud water corrosion. The housing is integrallycoated with color zinc, protecting against dust andwater from slurry erosion. It is resistant to rust andjamming during long-term use in rain, snow, andmountainous snow-melting salt environments, thusextending the service life of the adjustment arm.
5. Sufficient spot supply, domestic wholesale +foreign trade export supply. Jinan Heavy Truck PartsWarehouse maintains regular inventory, individualpieces, and bulk pickup, all enabling rapid shipment.Supports packaging of fumigated wooden palletsfor export, provision of customs declarationdocuments, and shipment from Qingdao and Tianjinports via FOB.
The adjustment arm failure scenario needs to be replaced.
1. Inconsistent left-left force of the brake, frequent deviations, Single-side drag brake fever
2. The brake pedal stroke fluctuates, the braking response is slow, and the brakes are braking.Not staying in a car
3. The adjustment gear is stuck, The gap cannot be automatically adjusted.
4. Housing corrosion, cracking, Gear wear and slippage, Fallure adjustment
5. Chassis overhaul and complete replacement of rear axle brake components
