The Makita 221526-1 is a genuine replacement sprocket for UC3520A and UC4020A electric chainsaws, restoring smooth power transfer from the drive shaft to the saw chain. Manufactured to Makita's original specifications, this steel sprocket ensures correct chain alignment and consistent engagement, helping to reduce unnecessary wear on both the guide bar and chain. Using a genuine OEM part rather than an aftermarket alternative gives tradespeople and grounds maintenance teams confidence in fit and long-term reliability. Key fitting dimensions of 11.8 mm between the oval ends and 8.9 mm between the flat ends make identification straightforward before ordering. Installation is direct and uncomplicated, making it a practical choice for site technicians and competent DIY users looking to return their chainsaw to full working order without unnecessary downtime.
