Product Description
The genuine TOYOTA (SKU: 90341-18040) plug (differential drain and fill plug) is a precision-engineered, high-strength fastener responsible for reliably retaining gear oil within the differential or transmission housing. This genuine (OEM) part guarantees a perfect fit and leak-free seal, protecting internal gears and bearings from premature wear caused by lubricant starvation and external contamination.
Technical Characteristics and Specifications:
- Manufacturer: TOYOTA (Genuine OEM part)
- Part Type: Straight plug (Plug, Straight)
- Application Area: Differential drain or fill port, transmission housing on select models
- Thread Size: M18 x 1.5
- Drive / Tool Requirement: Internal hex (hex socket) design for secure, high-torque fastening
- Material: Hardened steel with a durable, corrosion-resistant coating
Role and Importance of the Differential Plug:
Lubricating oil inside the differential operates under extreme pressure and temperature. The plug's function is to hermetically seal the system. An improper seal can lead to oil leakage, causing differential overheating and ultimately mechanical failure.
Typical Symptoms of Wear or Damage:
- Leakage: Oil residue or spots appearing on the differential housing around the plug.
- Damaged Threads: Overtightening can damage or strip the threads, preventing secure fastening.
- Stripped Tool Drive: Rounding of the internal hex socket due to using incorrect tools or a seized plug, complicating future fluid services.
Note: Whenever removing and reinstalling the plug, replacing the sealing washer/gasket is always recommended to ensure a leak-tight seal. Always observe the vehicle manufacturer's specified tightening torque.
