Makita 346177-0 — Guide Washer (genuine Makita replacement)
Restore smooth hammer action with the genuine Makita guide washer (part no. 346177-0). This small metal guide washer fits into the rotary-hammer/hammer assembly where it sits between the conical compression spring and the retaining ring to keep the spring and ring aligned and moving freely. It’s supplied individually and replaces worn, bent or broken washers that can cause binding, excess play, or abnormal wear in the hammer mechanism. A screwdriver and a pair of pliers are often helpful for installation.
Example models this part is used with (representative list):
- GRH07Z / GRH01M1 (40V XGT rotary hammers).
- DHR283 (28 mm combination hammer).
- HR2600 / HR2601 / HR2611F / HR2631F series rotary hammers.
- HR2300 / BHR242 and similar Makita hammer-drill models.
If the washer in your hammer assembly is damaged or missing, replacing it with the original Makita 346177-0 will help restore correct spring alignment and extend the life of the internal components.
