Wanliyang Manual transmission assembly WLY7TS60-70-00 9.165-0.830
Basic Performance & Vehicle Matching Parameters
| Parameter / Item | Technical Specification | Description & Remarks |
|---|---|---|
| Rated Input Torque | 600 N·m | Maximum torque allowable from the engine; strictly avoid overloading. |
| Rated Input Speed | 2600 rpm - 3000 rpm | Matches medium/light-duty high-speed diesel engines. |
| Forward Gears | 7 Gears | More gear steps compared to traditional 5/6-speed boxes, offering better heavy-load climbing power. |
| Reverse Gears | 1 Gear | Designed with a large ratio to ensure reverse power when fully loaded. |
| Gross Combination Weight (GCW) | 8 Tons - 18 Tons | Ideal for heavy-duty light trucks, medium trucks, and light-duty tippers. |
Gear Ratio Specifications
| Gear | Transmission Ratio | Power & Speed Characteristics |
|---|---|---|
| 1st Gear | 9.165 | Ultra-large starting ratio; specialized for heavy-load hill starts or off-road mud extraction. |
| 2nd Gear | 5.480 | Regular heavy-load starting gear, smoothly transitioning power from 1st gear. |
| 3rd Gear | 3.370 | Used for urban driving under heavy loads or slow-moving traffic conditions. |
| 4th Gear | 2.160 | Transition gear for mid-speed driving or charging up steep slopes. |
| 5th Gear | 1.430 | Frequently used gear for urban expressways and suburban arterial roads. |
| 6th Gear | 1.000 | Direct Drive; 1:1 rotation speed ratio between the input and output shafts. |
| 7th Gear | 0.830 | Overdrive; keeps engine RPM low at high speeds, optimal for highway fuel economy. |
| Reverse | 7.800 | High reverse ratio ensures backing-up power in muddy construction sites. |
Structural Design & Material Parameters
| Parameter / Item | Technical Specification | Description & Remarks |
|---|---|---|
| Housing Material | High-Strength Aluminium Alloy | Promotes excellent heat dissipation and significantly reduces weight (some heavy tipper versions use cast iron). |
| Shift Control Mechanism | Dual-rod / Remote flexible cable control | Offers lightweight shifting ergonomics and crisp engagement feel in the cabin. |
| Shift Structure Type | Full Synchronizer | Every forward gear features a synchronizer, eliminating the need to double-clutch. |
| Center Distance | 160 mm | Core structural parameter determining gear sizes and overall torque resistance strength. |
| PTO Window | Standard side/rear Power Take-Off ports | Can be fitted with hydraulic pumps for tipper lifting or special municipal operations. |
Installation, Lubrication & Maintenance Parameters
| Parameter / Item | Technical Specification | Description & Remarks |
|---|---|---|
| Clutch Housing Standard | SAE 2# or SAE 3# | International standard flywheel housing interfaces, defining the compatible clutch disc diameter. |
| Input Shaft Spline | Typically 10-spline / 14-spline straight spline | Verify input shaft dimensions carefully when purchasing the clutch pressure plate assembly. |
| Lubrication Capacity | Approx. 6.0 Liters | Fill until the fluid level reaches the lower edge of the oil inspection/filler hole on the side. |
| Recommended Oil Grade | GL-5 Grade 85W-90 Heavy-Duty Gear Oil | For freezing winter climates, changing to 75W-90 low-temperature gear oil is highly recommended. |
| First Oil Change Mileage | 2,000 km - 5,000 km | Mandatory break-in service to flush out microscopic metallic particles. |
| Regular Oil Change Interval | Every 40,000 - 60,000 km / or annually | Shorten the interval for tippers operating frequently under dusty or heavy-load worksites. |
