150-1007030A
Yutong Bus Parts
| Attribute | Specification |
|---|---|
| Part Number (P/N) | 150-1007030A |
| Alternate Part Numbers | 150-1007030, 615QC-1007030A, B30-1007030, 530-1007030 (verify fitment) |
| Product Name | Rocker Arm and Shaft Assembly |
| Brand Compatibility | Yuchai (Primary) |
| Engine Series | YC6G Series (e.g., YC6G230, YC6G240, YC6G270) |
| Application Type | Diesel Engines – Heavy-Duty Buses, Trucks, Construction Equipment |
| Material | Forged High-Strength Alloy Steel |
| Heat Treatment | Hardened and Tempered (surface and core strength enhanced) |
| Components Included | - Intake & Exhaust Rocker Arms – Rocker Shaft – Mounting Brackets / Supports – Adjustment Screws (Set Screws) – Lock Springs / Retainers – Bushings or Bearings (if applicable) |
| Net Weight | 9.5 kg – 11.0 kg |
| Manufacturing Standard | Meets Yuchai OEM Specifications; Micron-Level Dimensional Precision |
| Parameter | Detail |
|---|---|
| Design Function | Transmits motion from pushrod to valve stem; converts linear motion into pivoting action to open/close valves |
| Contact Surface Treatment | Hard-faced or stellite-coated rocker tips for enhanced wear resistance against valve stems |
| Oil Lubrication Pathway | Internal oil bore in rocker shaft ensures continuous pressurized lubrication to all pivot points and bushings |
| Valve Clearance (Typical) | - Intake Valve: 0.40 mm – Exhaust Valve: 0.45 mm (Adjustable per engine model and operating condition) |
| Torque Specification (Mounting Bolts) | 60–80 N·m (apply in crisscross sequence; tighten in multiple passes) |
| Operating Load Resistance | Capable of withstanding high-frequency impact loads (>3,000 cycles/min at idle) without deformation |
| Tolerance Precision | Machined to ±0.02 mm on critical dimensions (shaft diameter, bore alignment) |
| Compatibility Standards | Designed for use with mechanical lifters, pushrod-operated OHV systems in YC6G platform |
