At a Glance: Complete chuck and gearbox service kit (items 1–37) for the TC20190 RH500 20V SDS-Plus rotary hammer
Give your Tork Craft RH500 20V rotary hammer a new lease of life by replacing the complete chuck and gearbox assembly instead of retiring the tool. The TC20190-SK03 Rot/hamer 20V Replacement Chuck & Gearbox Complete (1–37) Service Kit brings together the critical front-end components that drive your SDS-Plus bits into concrete, brick and stone. When the original chuck, gearbox or housing is worn, noisy or leaking, this genuine kit restores smooth, confident hammer drilling and chiselling performance.
This kit covers a group of parts identified as items 1–37 on the TC20190 exploded diagram – typically including the SDS-Plus chuck assembly, gearbox housing and key drive components at the nose of the machine. Renewing these parts together helps ensure proper alignment, lubrication and impact transfer, so your cordless RH500 rotary hammer feels tight, accurate and ready for daily site work.
