SINOTRUK HOWO Twin-Countershaft Transmission Chassis Electrical System Gearbox Top Cover & Range Valve Wiring Harness WG220928000003
SINOTRUK HOWO Gearbox Top Cover Harness & Electrical Shift Control System Maintenance BOM
| BOM Level | Part Number (P/N) | Description (EN) | Qty / Vehicle | Key Technical Specifications / Remarks |
|---|---|---|---|---|
| 1.0 | WG220928000003 | Gearbox Top Cover & Auxiliary Case Wiring Harness | 1 Pc | Core Item: Base-version genuine wiring harness wrapped in high-density PA66 flame-retardant corrugated tubing. Equipped with multiple IP67 waterproof branch connectors. |
| 1.1 | WG2229280001 (or per gearbox model) |
Auxiliary Case Range Gear Shift Solenoid Valve | 1-2 Pcs | High-frequency companion item: Plugs directly into the 1.0 harness. If the harness previously shorted, it often burns or seizes this valve coil, causing a failure to shift between high/low ranges. |
| 1.2 | WG2209280015 | Gearbox Neutral Safety Switch | 1 Pc | Captures the gearbox neutral signal. If this switch is faulty or the harness has an open circuit here, the truck will completely fail to crank/start for safety protection. |
| 1.3 | WG2209280020 | Range Gear Position Sensor | 1 Pc | Monitors whether the auxiliary case is in the high or low range zone, corresponding to the high/low range indicator light on the dashboard. Green oxidation on the plug causes flickering lights. |
| 1.4 | WG9100580005 | Vehicle Speed Sensor (VSS) / Odometer Sensor | 1 Pc | Located at the rear output flange of the gearbox. On some SINOTRUK manual gearbox variants, the speed signal wires are merged directly into the 1.0 main harness trunk. |
| 1.5 | WG2214220002 (or per dual-valve spec) |
Range Air Control Valve Assembly | 1 Set | Pneumatic actuator valve controlled by the solenoid valve. If the electrical system is functional but high/low range still won't shift, this air valve or its soft seal kit must be replaced. |
| 1.6 | Industry Standard | Waterproof Heat-Shrink Butt Terminals | 1 Set | Consumable. Used if intermediate splicing or localized wire repairs are required near the chassis frame rail (features internal heat-activated adhesive adhesive sealing). |
| 1.7 | PA66 Flame-Retardant | Heavy-Duty Chassis Cable Ties | 1 Set | Essential consumable. Used to securely bind the new wiring harness to the pre-allocated brackets on the gearbox casing, preventing it from sagging onto the rotating propeller shaft. |
