Festool KAPEX KS 120 EB Replacement Gearbox Assembly

At a Glance: Genuine Festool replacement gearbox assembly for compatible KAPEX KS 120 EB sliding compound mitre saws.

The Festool KS 120 ET-BG(EB) gear assembly is a genuine replacement component for compatible KAPEX KS 120 EB sliding compound mitre saws. It forms a critical part of the machine&s drive system, transferring rotational power through the saw&s drivetrain towards the blade spindle.

A damaged or excessively worn gearbox assembly can contribute to abnormal mechanical noise, rough operation, excessive play, overheating or unreliable transfer of power. Replacing a professionally diagnosed faulty assembly with the specified Festool component helps restore the smooth and dependable drive performance expected from the KAPEX KS 120.

This is a specialist service assembly rather than a complete motor or an external saw accessory. Because multiple KS 120 production versions and regional configurations exist, compatibility must be confirmed using the complete machine type number and serial number. Installation, lubrication where specified, adjustment and final safety testing should be performed by Festool or a suitably qualified power-tool repair technician.

Restore the mechanical heart of the KAPEX drivetrain

The gearbox provides the essential mechanical link between the motor and cutting system. A correctly installed genuine replacement helps the saw transmit power smoothly while preserving the fit and alignment of the original Festool drivetrain.

Product Highlights

  • Genuine Festool spare part: Manufactured as the specified replacement gear assembly for compatible KS 120 machines.
  • Gear-case assembly: Supplied in assembly format for professional workshop replacement.
  • Drivetrain component: Forms an important part of the power-transfer system between the motor and blade spindle.
  • Model-specific design: Developed around the internal construction of applicable KAPEX KS 120 EB variants.
  • Professional repair solution: Allows a correctly diagnosed gearbox fault to be repaired without replacing the complete saw.
  • Traceable identification: Festool part number 205177 and GTIN 4014549371770 assist with accurate component selection.

Compatibility

  • Designed primarily for compatible Festool KAPEX KS 120 EB sliding compound mitre saws.
  • Listed in the spare-parts documentation for applicable 120V, 230V and 240V KS 120 EB variants.
  • Confirmed applications include selected machine type numbers such as 10037842, 10037846, 495649 and 495773.
  • Additional KS 120 EB variants may use this assembly when confirmed by Festool spare-part number 205177.
  • Compatibility depends on the complete machine type number, production version and serial number.
  • Do not assume compatibility with every KS 120 REB or other KAPEX model without confirmation from Festool.

Extra Information

  • This product is a replacement gearbox assembly and not a complete Festool KAPEX mitre saw.
  • It should not be confused with the separate 45-tooth gear, pinion, motor, armature, motor housing or blade flange listed elsewhere in the KS 120 assembly.
  • The precise components supplied as part of the assembly may differ from individually listed surrounding parts in the exploded diagram.
  • Confirm the machine&s complete type number and serial number with Festool or an authorised service representative before ordering.
  • Noise, vibration or loss of power does not automatically indicate gearbox failure. The blade, bearings, motor, electronics, spindle and other drivetrain components should also be inspected.
  • Associated fasteners, seals, bearings, lubricant and neighbouring service components are not included unless specifically supplied with the gear assembly.
  • The saw blade, motor, external guards and machine accessories are not included.
  • After installation, the complete blade-drive system, spindle lock, guard operation, brake and cutting alignment must be inspected before the saw is returned to service.

Pro Tips

  • Record the complete T-number and serial number from the KAPEX rating plate before requesting compatibility confirmation.
  • Have the original assembly inspected before ordering, as worn bearings or motor components can produce similar noise and vibration.
  • Inspect the blade spindle, pinion, bearings, seals, mounting points and surrounding drivetrain components while the saw is dismantled.
  • Use only the lubricant type and quantity specified in the Festool service documentation.
  • Retain the original gearbox and all removed components until the replacement assembly has been installed and tested successfully.
  • After the repair, run the saw without load and then complete controlled test cuts before returning it to normal workshop use.

Features

  • Original Festool component: Provides the manufacturer-specified replacement instead of an adapted universal gearbox.
  • Assembly configuration: Listed by Festool as Gear KS 120 ET-BG(EB), indicating a replacement assembly for the applicable machine.
  • Precision-machined drivetrain component: Designed to work with the corresponding motor, bearings and spindle components.
  • KS 120-specific fit: Produced around the mounting arrangement and internal layout of compatible KAPEX KS 120 EB saws.
  • Mechanical compatibility: May be used across applicable voltage variants where confirmed by the machine&s spare-parts documentation.
  • Professional service part: Intended for authorised Festool service centres and suitably equipped power-tool repair workshops.

Benefits

  • Restores power transfer: Replaces a damaged assembly responsible for transmitting drive towards the blade spindle.
  • Supports smooth operation: Helps correct roughness, abnormal mechanical noise or excessive play caused by a confirmed gearbox fault.
  • Maintains correct fit: The model-specific assembly integrates with the applicable original Festool components.
  • Protects the machine investment: Enables an otherwise serviceable KAPEX saw to be professionally repaired.
  • Reduces adaptation risks: Using the specified Festool component avoids the uncertainty of modifying a generic gearbox or gear case.
  • Supports long-term servicing: Provides a dedicated replacement solution for professional maintenance of the KS 120 platform.

Application

  • Replacement of a professionally diagnosed damaged KS 120 gearbox assembly
  • Repair of excessive mechanical play within the saw&s drivetrain
  • Correction of abnormal gearbox noise or rough operation after proper diagnosis
  • Restoration of reliable power transfer to the blade spindle
  • Professional refurbishment of compatible KAPEX KS 120 EB saws
  • Festool service-centre and qualified power-tool workshop repairs

Safety

  • This gearbox assembly should be installed only by Festool or a suitably qualified power-tool repair technician.
  • Disconnect the saw completely from the mains supply before inspection, disassembly or servicing.
  • Remove the saw blade before working on the gearbox or surrounding drivetrain components.
  • Be aware of sharp components, spring-loaded mechanisms and heavy moving assemblies within the saw head.
  • Do not operate the machine if the gearbox, spindle, bearings or mounting components show excessive movement or damage.
  • Use the correct fasteners, tightening torques, lubricant and assembly procedures specified by Festool.
  • Verify that the blade rotates freely and does not contact any guard, housing or internal component after installation.
  • Test the spindle lock, blade guard, motor brake and all other protective functions before returning the saw to service.
  • Stop the saw immediately if abnormal noise, excessive vibration, overheating, smoke or a burning smell occurs.
  • Follow the Festool service documentation and all applicable electrical and machinery safety requirements.
