803163983 XCMG GR2605 motor grader breath plug type B

The 803163983 Type B vent plug is a specialized sealing and venting accessory for construction machinery. It is used for venting, moisture protection, and dust prevention in equipment enclosures (such as gearboxes and hydraulic oil tanks). Its structure is compatible with Type B installation interfaces, providing a tight seal, easy installation, and suitability for heavy-duty conditions, ensuring the normal operation of internal components.

Core Technical Parameters

1. Model: 803163983, Type B vent plug, specifically for construction machinery, precisely matching the host machine’s venting interface.

2. Compatible Media: No specific media; primarily used for venting, moisture protection, and dust prevention in equipment enclosures.

3. Material: High-quality carbon steel/stainless steel, heat-treated for high strength, corrosion resistance, and minimal deformation.

4. Operating Temperature: -40℃~120℃, suitable for harsh outdoor and oily environments.

5. Surface Treatment: Zinc-plated passivation/blackening treatment for rust and corrosion prevention, extending service life.

6. Specifications and Dimensions: Compatible with Type B mounting interfaces, with precise matching of inner and outer diameters, requiring no additional adjustments.

7. Sealing Performance: Built-in sealing structure ensures smooth ventilation while effectively preventing dust and moisture from entering the equipment housing.

8. Adaptor Interface: Specifically designed for the ventilation ports of engineering machinery housings (gearboxes, hydraulic oil tanks, etc.), providing a tight fit.

Core Functions and Roles

Core function: Used for ventilation and heat dissipation in various engineering machinery housings (gearboxes, hydraulic oil tanks, etc.), expelling excess gas from the housing, balancing internal and external air pressure, and preventing leakage due to excessive air pressure; it also provides excellent sealing and protection performance, preventing external dust, moisture, and oil from entering the housing, preventing corrosion and damage to internal gears and hydraulic components, and ensuring the normal operation of the equipment’s transmission and hydraulic systems; the structural design is compatible with Type B interfaces, facilitating easy installation and rapid assembly, suitable for heavy-duty and high-frequency vibration construction conditions.

Suitable Applications

Widely used in various construction machinery such as excavators, loaders, bulldozers, and mining machinery. It is compatible with various enclosures requiring ventilation and sealing, such as gearboxes, hydraulic oil tanks, and gear sets. Suitable for heavy-duty, dusty, and humid operating environments such as infrastructure construction, mining operations, and road construction, it is a fundamental accessory ensuring the normal operation of internal components.

Common Faults and Troubleshooting

When ventilation is insufficient, check for blockages in the vent holes or aging seals. Clean impurities from the vent holes or replace the seals. When the seal fails, or there is air/water leakage, check for wear on the sealing structure and damage to the surface protective layer. Replace with a new vent plug. If the installation is loose, retighten it to ensure a tight fit with the enclosure interface to prevent dust and moisture from entering. If rust causes jamming and installation is impossible, clean the rust from the interface or replace the vent plug directly.
