Siegenia SI Favorit Trial Drive Gear Tilt Turn Window Repair Replacement Gearbox and Patio Door Drives 1 X Number Quantity 

The SI Siegenia Favorit tilt turn window lock mechanisms are no longer made and are now obsolete. The new range that has superseded them has been done so assuming that all the gearing around the window will be replaced at the same time and therefore the connection points are no longer compatible meaning that you cannot fit the new parts to the old exsisting ones as a replacement repair. 

However we have been able to source and create an excellent solution so that you can repair the old and no longer available window drive gears which is the part that usually fails. Just like repairing a door lock mechanism you can now replace the centre drive gear box with our unique engineered repacement SI gear box built to the same specifications.

The new Siegenia gearboxes FAVORIT series is now avaialble as a matching replacement spare part. The 2 sides of the gear box parts are connected with metric PH1 screws which is avaialble as a common screwdriver or bit (not included).

Siegenia Favorit Trial drive gears always came with the lock in the central open position. Inside the gearbox Siegenia position the gear with a break off burr inside the lock to prevent the lock moving whilst it is cut down to length to suit the particular patio. On first operation it will feel like the lock is jammed but as you exert some force on the handle you will find the burr breaks off and the lock will now run free from here on in.

Please note that the pre-cut holes in the plate that the serretated teeth are connected to which the gear engages is re-used. If it is badly worn, then the new gear-box cogs can no longer grasp it properly and move it reliably.

1 X Centre gearbox as shown 
1 X Fitting instruction sheet

This is a SI Siegenia Trial Favorit tilt turn drive gear centre gearbox replacement to suit the Favorit SI Siegenia titlt turn & patio type window locks. Sold as 1 x gearbox
