1. Basic product parameters
Part Number: 199012320503
Product Name: Rear Axle Differential Assembly(Transmission Housing Assembly) ApplicableModels: Shaanxi Delong, Steyr Heavy Truck SeriesApplicable Location: Rear Axle Chassis Drive Axle
roduct process: Precision steel casting, CNC fine grinding, and overall quenching and tempering area
2. Core Product Advantages
High-strength housing material
It is integrally formed with thickened cast steel, offeringstrong toughness, resistance to heavy loads, shock
resistance, and resistance to cracking or deformation duringlong-term heavy-load driving. It is suitable for long-distanceheavy load, and complex mountain road conditions
Precision transmission noise reduction and wear resistance
The gear tooth profile is accurately calibrated, withtight engagement and uniform clearance, effectivelyreducing abnormal noise and jitter issues after driving,offering high transmission efficiency, minimal powerloss, and significantly improving driving stability.
riginal factory standard hole position
Production is strictly carried out according to originalfactory parameters, with installed hole positions, preciseinterface matching, non-destructive direct replacementof original parts, no need for polishing or modification,convenient installation, and saving time and effort.
Sealed and durable, resistant to damage
The supporting sealing structure is robust, dustproofand oil leakage prevention, effectively protecting theinternal gears and bearings, extending the overallservice life of the rear axle, and reducing the frequencyand cost of subsequent maintenance
3. Suitable for fault replacement scenarios
fthe vehicle encounters the following issues, it is recommended to replace the differential switch promptly.
Cheng:
Heavy load, humming noises and odor impacts occur on the rear axle during turns
Sound
The vehicle is misaligned, and one-sided wheel power is abnormal
The original differential housing is cracked, deformed, and the gears are severely worn.
Frequent oil leakage in the rear axle, excessive bearing clearance, and transmission vibration
