Help needed please on our Hymer skylight

[goneoff]

Our Hymer MLT 580 2016 has a central roof light/skylight with a crank handle that raises it parallel to the roof. The problem I have is that ours comes down not perfectly parallel. When cranked tightly down, the front of the skylight sits directly on the roof, but the rear sits away from the roof by approximately 10mm. Does anyone know if there is a way of adjusting this so that both front and back sit directly on the roof? Or perhaps it shouldn’t sit directly on the roof. Thanks in advance.

Our skylight is same design but different Hymer model , we have a gap all round ours it seals against the rubber on the skylight frame

As posted by DavidG58 above, I don't think they should touch the roof, rather sit on the rubber seal surround.
If yours aperates on the same mechanism as mine, the four arms which raise the roof are linked by rods on the winder side and so should go up and down in unison with rods going from left to right which join the 2 front arms and the other links the rear arms. Without taking the skylight off (4 star washers), I can't remember if the front and back are adjustable seperately

I agree that the inner 'glass' should sit on the rubber seal, not the outside on the roof.

On our 780, you can put your finger around the rubber and feal the window is sitting on the rubber.

Yes that’s just the same skylight as ours only difference being it runs lengthways with the van. I shall take a look and see what I can and cannot adjust. The interesting thing is the fact that it should not fit directly on the roof. Thank you, very helpful

Thank you. At least now I know how it should sit on the seal. Cheers

Easy enough to get the skylight off, 4 'star' washers holding it on - You'll need new ones to replace - can't remember the size but you should be able to get a gauge on the end of the bar which holds the washers on, get half a dozen before starting the job (stainless to stop rust running down your roof DAMHIK). I pushed mine on with a small socket over them to keep them square as I pushed them into place. Old ones came off with a pr of small pliers if I recall.

I found a small bolt attached to the crank arm on the roof that must have sheered off some time ago. I’ve now replaced it and the skylight works as it should. Thankfully didn’t need to take the skylight off.
Thanks again for your response and effort to help

It is not designed to sit on the roof. The flat part of the window seals to the rubber at the top of the upstand.
