Achkey Siegenia (SI AUBI) worm housing auger replacement part screwable for window gearbox and balcony door repair gear lock for series Favorit TRIAL gearbox 3 & 23 with HauSun upgrade

• Replacement part Siegenia worm housing: repair replacement housing for defective gears fits many Siegenia gearboxes from the Favourit series.
• Three-piece gear with screws: These are original gear locks, which are converted by us into a repair kit.
• Tool: the gear shells are connected with metric PH screws (PH1). So you only need a PH1 bit or screwdriver (not included).
• Suitable for windows and balcony doors: the gear lock has an adjustment lock, which breaks during the first operation and releases the gearbox.
• Please note: the hole bar can still be used in the gear. If it is heavily worn, the gear can no longer grasp it properly and move it reliably.
