Makita 267732-4 Spare Part - *LOCK WASHER 12 BUC121/122
Genuine Makita Lock Washer 12 — part no. 267732-4.
A stamped lock washer identified as "12" in Makita parts diagrams that secures the sprocket/spindle assembly on compact Makita chain- and pruning-saw drive units.
Fits applications shown in Makita parts breakdowns for models such as BUC121, BUC122, DUC122 and XCU01; it's listed as the replacement lock washer used under the sprocket/sprocket-cover assembly. This is a common item in Makita parts lists for those saw models.
If the original washer is deformed, worn or no longer holds the sprocket tight, this genuine Makita replacement restores the correct preload and retention in the chain-drive stack — a small, precision-fit part that avoids sprocket movement and premature wear. It's a standard small component you’ll find among parts for power tools when servicing the sprocket/drive area.
