Its precisely cut grooves ensure positive engagement with the pulleys, minimising slippage and wear. The belt is designed to withstand the high temperatures and loads of the engine bay, ensuring long‑lasting performance.
The Bolt is a high‑strength tension stud used to adjust the belt tension and secure the compressor mounting bracket. Manufactured from grade 8.8 steel with a corrosion‑resistant coating, it provides reliable clamping force.
Its precise threading allows for fine adjustment of belt tension, ensuring optimal power transfer and reducing belt wear. This bolt is essential for maintaining proper compressor alignment and drive system efficiency.
The 2 type full metal hex locking nut is a prevailing‑torque lock nut that provides a secure, vibration‑proof fastening for critical chassis and engine bay connections. Its all‑metal construction ensures excellent temperature resistance and durability.
The locking feature prevents loosening due to vibration, making it ideal for the high‑stress environment of the compressor mounting area. This nut is used in conjunction with the bolt to ensure a tight and reliable joint.
The Flat washer is a standard flat disc used to distribute load and protect the mounting surface from damage. Manufactured from steel with a protective coating, it provides a smooth bearing surface under the bolt head, reducing friction and preventing galling during tightening.
Its use ensures that the clamping force is evenly distributed, preventing localised stress and ensuring a secure, rattle‑free connection. This washer is an essential hardware component of the Inner Refrigerant compressor & belt kit.
The Block is a precision‑machined spacer that provides the correct offset between the compressor and the mounting bracket. Manufactured from high‑strength aluminium or steel, it ensures accurate alignment of the compressor pulley with the belt drive system.
Its precise dimensions guarantee that the belt runs true, reducing vibration and extending belt life. This block is a critical component for achieving optimal compressor installation geometry.
The Spring washer is a split‑helical locking washer that provides preload and prevents loosening of fasteners under vibration. Manufactured from high‑carbon spring steel, it maintains tension on the bolt, ensuring that all connections remain tight even under high vibration.
This washer is used in critical joints of the Inner Refrigerant compressor & belt to ensure that all fasteners remain secure over the vehicle’s lifetime. Its robust design makes it an indispensable locking element.
The 1 shape hex nut is a standard hexagonal nut that provides a reliable, vibration‑resistant fastening for various components. Manufactured from steel with a corrosion‑resistant coating, it ensures a secure connection that maintains clamping force under extreme conditions.
This nut is used in conjunction with bolts to secure the compressor and its mounting hardware, ensuring a durable and reliable installation.
The Axle sheath is a precision‑machined bushing that provides a low‑friction bearing surface for the compressor pivot or mounting pin. Manufactured from high‑grade bronze or self‑lubricating polymer, it reduces wear and ensures smooth articulation.
Its precise fitment ensures that the compressor remains correctly aligned during belt tension adjustment, preventing premature belt wear and ensuring consistent compressor performance.
The Hex bolt is a high‑strength fastener with a hexagonal head, designed for securing the compressor and its mounting brackets. Manufactured from grade 8.8 steel with a corrosion‑resistant coating, it provides excellent clamping force and resistance to vibration.
Its precise threading ensures easy installation with standard wrenches, and its robust construction guarantees that the compressor remains securely attached under all operating conditions.
The Washer is a small‑diameter flat washer that provides load distribution under the bolt head in confined spaces. Manufactured from steel with a protective zinc coating, it prevents damage to the mounting surfaces and ensures a secure connection.
Its compact size makes it ideal for use where space is limited, ensuring that the clamping load is properly distributed without interfering with adjacent components.
The Shealth is a durable bushing that provides a low‑friction bearing surface for the compressor mounting or adjustment mechanism. Manufactured from high‑quality engineering plastic with excellent wear resistance, it ensures smooth operation and long service life.
Its precise fitment reduces play and vibration, contributing to the overall stability and quietness of the A/C compressor drive system.
