Ok, so thanks to the LR forums and Youtube, headliner out, sun roofs out, sunroof motors opened and greased, drain cups removed and replaced, sunroof tracks greased, sunroof glass seals removed and replaced.

Which brings me to the current issue. I have quadruple checked that the seals are installed correctly and completely seated. None of the channel grooves are showing. The seal is also not backwards based on YouTube videos. The problem is the the seal is tall and doesn't lay down flat like the old one so the closing mechanism won't get to the completely closed portion. I'm using the motor handheld and turning with Allen wrench on the the workbench. But it takes significant force to get it as far closed as I can, but it's still not in completely closed position.

1. Will this get remedied with everything fully installed on Rover? It doesn't seem so based on how hard I have to crank it to try to close it.

2. Is there a way to get the seal to lay more flat? The glass engages it and seems to the pinch it the wrong direction and leave a large gap on the backside of the seal against the plastic. The seal stands more vertical than the old seal I removed. I started to try to clamp it down. Will a heat gun help?

This is fully closed without glass attached.


This is as far as I can get it to close by hand. This is with me squeezing the glass closed with my hands while having someone turn the motor.

This is gap that stays open even with glass closed/engaged on the seal.

Again, more backside gap.

This is how I want the seal to lay/close but it doesn't do it on its own. The glass closes on top of seal and leaves gap open


The only idea I had.


Thanks for help. Pics attached.

 

It doesn't look like your seal is inside out (ie the "lip" faces outwards not inwards) so it's not that. Anyway, this past summer I had same issue. My first problem was the inside out seal. Fixed that, still too tight to properly close. Both sunroofs would get stuck (and note: on mine this was 2 NEW motors and 2 NEW track assembly from JLR ($$$$$$$$$). I was very unhappy.

These crap-part (britpart) seals in the blue bags are a bit bigger out of the gate.

What I did -- very very loosely install the sunroof glass w/ the 4 Torx screws. As in just enough to hold the glass on but it's still a bit loose. Then close the roof. Carefully. Once closed, move the glass around to the centered position from above on the roof with plastic trim tools (once closed - get the gaps even). Then -- Once closed and centered, snug down the glass when it's closed and let it sit outside in the sun. Note the torque setting on those 4 sunroof screws (black w/ the blue locktite) is ... quite low.

Something about having the glass snugged up prevented mine from closing. But doing it this way was enough to compress the new seals. After a week or two, it's fine. Mine open and close perfectly. When the seal was new it would get caught just where yours did.

The issue is the britpart seal. It's too thick. BTW their RRC seals for the tailgate are also too thick.

 

Thanks!

Did you do all of that on table top, hand holding and cranking the motor or installed on the Disco first with motor screwed in and crank it there?

 

Did this on the car... installed.
