HOWO LIGHT TRUCK ZZ1107D3815C CLW5120RS7 Differential assembly
Internal Core Structure and Components
1. Reduction Gear Set (Ring and Pinion Gears): Comprising a drive pinion and a large driven ring gear, this set reduces the rotational speed from the drive shaft while multiplying the torque.
2. Planetary Gear Mechanism: Consisting of four planetary gears, a cross-shaft, and two side gears (half-shaft gears), this mechanism automatically distributes rotational speeds between the wheels on either side when the sprinkler truck turns.
3. Cast Iron Load-Bearing Reducer Housing: A high-strength ductile iron casing that encloses and secures the aforementioned gears, utilizing tapered roller bearings to withstand the immense reaction forces generated by the vehicle's drivetrain.

Routine Maintenance and Servicing Specifications
1. Gear Oil Specifications: High-grade, heavy-duty automotive gear oil must be used-typically 85W-90 or 80W-90 (GL-5 grade). Do not use standard, low-grade gear oil; otherwise, the oil film may rupture under high-load, high-temperature conditions, leading to rapid gear scoring or seizure.
2. Oil Change Interval: For new vehicles or after replacing the differential assembly, an initial mandatory oil change must be performed after 1,500–3,000 km of driving to flush out metal particles generated during the break-in period. Thereafter, it is recommended to change the gear oil every 20,000–30,000 km.
When to Replace
1. Severe abnormal noise: A "humming" or grinding sound emits from the rear axle when accelerating, and the sound changes or disappears when the throttle is released (usually caused by damaged ring and pinion gear teeth or burnt-out bearings).
2. Excessive backlash at start-up: After disconnecting the driveshaft, manually rotating the differential input flange reveals excessive play, and a distinct clunking sound is heard from the rear axle when starting to move (usually caused by worn planetary gears or shims).
3. Slippage and gear failure: Sudden, violent traction recovery after severe wheel spin on muddy construction site terrain causes internal gears to shatter, rendering the vehicle completely inoperable.
