Original Makita spiral bevel gear — part number 141458-5 (listed as "Spiral Bevel Gear 11 Complete") — a single 11‑tooth spiral bevel pinion supplied as the complete gear assembly for the gearbox of 18 V SDS+ rotary hammers. This genuine Makita replacement is the precision tooth set that transfers torque from the rotor into the hammer drive and is sold as one complete gear unit. Fits Makita DHR242 and DHR243 and BHR242 / BHR243. This is a commonly replaced drivetrain component on those rotary hammers; it’s listed in Makita parts price lists as the Spiral Bevel Gear 11 Complete.
If you need the part to restore correct engagement and smooth hammering action, this original Makita 141458-5 slip‑in gear installs in the gearbox / armature area and replaces the worn pinion that causes skipping, grinding, or loss of impact. It’s a direct-fit gear assembly specified by Makita for those models and intended for use during gearbox or rotor service on compatible units.
Note: this listing is for the single complete spiral bevel gear (part 141458-5); keep your model number handy when ordering since the DHR242 / DHR243 parts diagrams show the exact location and orientation for installation. This item is one of the small but critical Makita parts mechanics look for when repairing rotary hammers — a straightforward repair on many SDS+ rotary hammer models and a typical item among parts for power tools.
