Original Makita spiral bevel gear — part no. 227588-7. This is a 32‑tooth spiral bevel gear manufactured as the gear that sits in the transmission / gearbox of Makita 24 mm cordless combi / rotary hammers (example models: DHR243 and BHR242 / BHR243).
Precision-machined for correct meshing in the hammer drill gearbox and sold as "Spiral Bevel Gear 32 (complete)" on Makita parts diagrams; it installs in the gearbox assembly (item 60 on the exploded view) and pairs with the nearby retaining ring and ball bearing shown on the diagram.
If you’re repairing a DHR242 / DHR243 / BHR242 / BHR243 combi hammer and the internal drive gear is chipped, cracked or worn, this genuine Makita replacement restores the correct tooth count and geometry for reliable engagement and hammer / drill function listed in Makita parts
