I've got a double glazed window in which the handle no longer works. Unscrewed the handle - spindle okay, so the problem must be elsewhere in the mechanism.
I've managed to get the window open (by removing the glass and twisting the frame) and I can see that the pin that comes out of the left hand side into the frame is no longer retracting. Equally on the right side the pin won't extend into the frame, so it never closes properly.
I suspect something inside has snapped so need to replace it, and now I am baffled by the terminology and I'm not sure what to buy. I think I'm after an espag gearbox. Looks like they're only a tenner or so but I'm not quite sure if it's enough.
Various figures are given but it's not entirely clear what dimension they refer to.
E.g. My window aperture, between the reveals, is 110 cm. (top hinge by the way so the mechanism is a right pain to get a look at). The gap in the frame is 102, and the distance between the pins/rollers that slide into various slots is 97 cm. Also the slots they engage with area also broken - metal fatigue I assume, so they may need replacing to.
Also - the top right corner doesn't quite sit flush either. There is a triangular bit of metal which assume is to pull it properly in, but can't quite see why it's not working.
What bits do I need to measure in order to get the right thing?
Brand is Mila if that's any help.
Please enlighten me if you can
