How to adjust this hinge?

Hey all,

I'm trying to see how to adjust the door hinge in the photos attached. I believe the white 'front' needs to come off but it doesn't seem to want to budge.



Cheers,

They're all pretty much the same as this

Thanks Crank39. I have a couple of questions if that's ok..

1) Does the middle bit (looks like a cover) not have to come off to adjust the hinge using the adjustment on the far right? I was told that there's two locking nuts that need loosening before you can adjust it 'side to side'?

2) I can see from your image that the far right bolt adjusts it side to side and the top bolt adjusts it up or down but what does the bottom bolt do? Is that also side to side?

Hope that makes sense!

1) No it doesn't that's why there is a cap covering the hole for access to the allen key adjuster but if you want to remove the cover try pressing the square area on your second picture with a screwdriver, on some hinges this releases the front cover

2) This illustration is actually wrong in as much that the top bolt and bottom bolt should be the other way around. The bottom bolt pushes the hinge pin up out of the housing thus lifting the door straight up, the top bolt acts like a cam and turning it through 360° will move the door in and out increasing or decreasing compression on the rubber seals
