203-4827 Fan Blade — Cat 248 226D

This fan blade is essential for the engine's cooling system, drawing air through the radiator to dissipate heat. It is constructed from durable materials to withstand high rotational speeds and environmental exposure. A cracked or unbalanced fan blade can cause excessive vibration, reduced cooling efficiency, and potential damage to the fan shroud or other engine components.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

A failing fan blade may first present as an unusual whistling or flapping noise at higher engine RPMs, or noticeable vibration transmitted through the machine. If the damage progresses, the blade may lose efficiency, leading to gradual engine temperature increases under load. In severe cases, a broken blade can cause significant damage to the radiator, fan shroud, or other engine accessories.

Installation Tip

Before installation, check the fan hub and mounting bolts for any signs of wear or damage. Ensure the fan blade is correctly oriented to pull air through the radiator, not push it.

Service Note

Inspect the fan belt tension and condition, as well as the radiator and fan shroud, when replacing the fan blade.
