90552006 supersedes older part numbers: 477486-00

Original DeWalt replacement timing belt — part number 90552006 — designed to sit on the motor drive pulley and link the flex shaft to the cutting spool on compatible line trimmers.

Technical details: HTD 3M tooth profile (3 mm pitch) with a pitch length of 231 mm (which corresponds to 77 teeth) — the standard 3M-231 synchronous belt used in these small trimmer drives.

Example fitment: this original DeWalt belt is used on a number of Black & Decker / DeWalt-style trimmers — for example GH11000 , GL701 , GL710 , GL716 , GL720 and GL741 — so it’s a direct-match replacement when the cogs wear or the drive starts slipping.

Compact and ready to install, this genuine DeWalt part is a smart addition to your DeWalt parts collection — a small component that gets the flex-shaft drive turning again and keeps your trimmer working. It’s one of those essential parts for power tools that solves the common belt-wear issues quickly.
