This genuine Tanaka clutch spring is an OEM replacement part used across a range of Tanaka handheld outdoor power equipment. Its purpose is to maintain correct clutch tension, ensuring smooth take‑up when the engine accelerates and preventing premature clutch slippage. As clutch springs are subject to constant load and heat, they can weaken over time. Replacing a worn spring helps protect the clutch drum, shoes, and drive system from further wear.

The spring is manufactured to Tanaka’s original specifications and is a direct replacement for part numbers 3420630B20 and 3420630B200. Being an OEM component means it fits correctly and maintains the same performance characteristics as the original part supplied with the machine. It is suitable for owners, technicians, and commercial operators who want to keep their equipment operating reliably.

Refer to your model’s parts diagram or workshop manual to confirm compatibility before installation.
