Makita 135615-5 Spare Part - SPUR GEAR 43 ASSY UC3541/4041

Genuine Makita spur gear assembly — part 135615-5. This original Makita 43‑tooth spur gear is the drive gear used in the chain/drive train on several Makita electric chain saws; it’s the replacement gear shown in the exploded parts diagram (ref. position 53).

Why this part: it replaces a worn or damaged drive gear to restore smooth engagement and correct chain drive alignment, and is supplied as the complete gear assembly to make installation straightforward.

Example models it fits (for reference): UC3041A, UC3541A, UC4041A — also shown as compatible with Makita/Dolmar ES34TLC, ES39TLC and ES43TLC in parts listings.

Short, practical notes: listed as "Spur Gear 43 Ass'y" (part no. 135615-5) in Makita parts diagrams; order this original Makita gear if your saw shows stripped or chipped gear teeth or uneven chain drive.
