Tork Craft Polisher Service Kit Speed Control And Capacitor (37, 40) For POL05
At a Glance; Speed control module and capacitor kit (items 37 and 40) for the Tork Craft POL05 rotary polisher.
Bring the electronics of your Tork Craft POL05 back into line with this genuine speed control and capacitor service kit.
The speed control module manages the polisherâs adjustable speed range, while the capacitor helps smooth power delivery and reduce electrical noise, so the machine starts cleanly and runs consistently under load.
When these components begin to fail, you may notice surging rpm, dead spots on the speed dial, poor low-speed control or nuisance tripping on start-up.
The POL05-SK12 kit replaces the original speed controller and its matching capacitor (items 37 and 40 on the parts diagram), restoring stable, predictable speed control for professional polishing, cutting and finishing work.

Features
- Genuine Tork Craft speed control and capacitor kit for the POL05 polisher.
- Includes electronic speed control module and companion capacitor (items 37, 40).
- Factory-matched components for the original POL05 motor and trigger layout.
- Designed to deliver smooth speed adjustment across the working range.
- Capacitor helps reduce electrical noise and improve starting behaviour.
- Suitable for demanding panel shop and detailing environments.
Benefits
- Restores reliable variable speed control for precise polishing work.
- Reduces rpm hunting, surging and flat spots at certain dial settings.
- Improves low-speed control on sensitive edges, profiles and finishes.
- Helps reduce nuisance tripping and harsh electrical starts.
- Extends the life of the POL05 by returning the electronics to original spec.
Extra Information
Typical signs that the speed control and capacitor need attention include a polisher that runs only at full speed, loses drive at lower settings, pulses or surges under steady load, or behaves erratically when you adjust the dial.
In some cases the machine may fail to start reliably or trip power protection, even though the cable, brushes and bearings are in good condition.
The POL05-SK12 kit uses genuine components specified for the Tork Craft POL05, so the wiring layout, mounting points and control characteristics all match the original design.
Fitting the correct controller and capacitor helps the tool feel "as new" again, especially when paired with fresh brushes and a healthy armature and stator.
Pro Tip
Pro Tip: Before removing the old speed control and capacitor, take clear photos of all wiring connections and note the cable colours and positions.
When fitting the POL05-SK12 kit, route the wires neatly away from moving parts, secure them in their original clips and double-check every connection before closing the housing.
After reassembly, test the polisher with no load and sweep the speed control through its full range to confirm smooth, stable rpm before going back onto paint.
Safety
- Always unplug the polisher from the mains before working on any electrical components.
- Allow the tool to cool down fully before opening the housing.
- Discharge and handle capacitors with care avoid touching bare terminals.
- Ensure all electrical connections are correctly insulated and routed away from moving parts.
- Refit all covers and screws securely and test the polisher under no load before normal use.
- If you are unsure about electrical repairs, have the work carried out by a qualified technician or an approved service centre.
