Hitachi 961-781 Spare Part - Brush Cap

Original Hitachi brush cap — part no. 961781. This is the threaded brush access cap used to seal and secure the carbon brush holders on compatible Hitachi (Hikoki) corded tools. It’s a molded, hard-wearing plastic cap that keeps dust and debris out of the brush chamber while helping maintain stable brush contact with the commutator for reliable motor performance.

Key details you’ll want to know:

- Function: screw-in cap for the brush holder; protects the brushes and motor internals from dust and impact while holding the brush spring assembly in place.

- Construction: durable molded plastic made to resist heat and vibration; designed to match the original Hitachi thread and seating for an exact fit.

Example models this part is used on : H55SA / H55SC grinders/hammers, C9BA2, C9BU2 / C9BU3 and other C9-series circular saws, DH35 / DH38YA hammer drills, SAT-180 sanders and several M8-series routers. These model references come from Hitachi/Hikoki parts diagrams and listings that show 961781 as the brush cap.

Fit and installation notes:

- Replacement is straightforward — remove the worn or damaged cap from the brush holder and screw in the replacement until seated; ensure brushes and springs are correctly positioned before tightening. The cap is sold individually, matching the original Hitachi specification for a correct fit.

If your tool’s parts diagram lists 961781 as the brush cap (often item “brush cap” or “brush cover”), this is the original Hitachi cap you need to restore proper brush retention and motor protection.
