557-7607 Suction Fan Spacer
Cat® Drive Assembly Suction Fan Spacer
Description
The suction fan spacer is installed between the fan adapter and the fan pulley hub to ensure proper clearance and prevent any damage caused by contact between the two. The fan adapter is the component that connects the suction fan to the engine, and the fan pulley hub is the component that transmits power from the engine to the fan. A spacer is used to provide precise spacing between two or more objects. A hollow spacer is lighter in weight and allows more flexible customization, and can be used in applications that prioritize weight reduction and require fluid flow.
Features
- Through-hardened for a harder surface.
- Built to exact specifications for durability, reliable performance, and outstanding productivity.
- Resists corrosion in harsh environments.
Applications
The shim creates a small gap between the fan adapter and the fan pulley hub, helping to prevent contact.
