Original Makita compression spring — part no. 232411-3. This small but critical compression spring is listed by Makita as "Compression Spring 8" (nominal 8 mm) and is the replacement spring used in the hammer/impact assembly of several Makita rotary/demolition hammers.
Fits (example models): Makita DHR400 / DHK180 and Makita HM001G (XGT cordless demolition hammer) check your tool’s parts breakdown to confirm the same part number before fitting.
Why this part matters: the spring restores correct preload and return action in the tool’s impact mechanism so the hammer functions smoothly and safely. Supplied as an original Makita replacement (part 232411-3), it’s ready to drop into the existing assembly without modification.
If you need a direct, genuine Makita replacement spring with the right nominal 8 mm specification for the models above, part 232411-3 as shown in Makita parts list for rotary/demolition hammers.
