audiman Posted July 26, 2009 Share Posted July 26, 2009 got the common rotten boot floor problem on my disco1 v8 looking to replace it with a new one and have seen an alloy one on ebay at reasonable money my question is this i would be pop riveting it in but a mate has said that it would fail its mot for the rear seat belt mounting point if there are pop rivets in this area is this correct? I thought the seat belt mounting point bolted to the crossmember underneath thanks in advance for any help on this one cheers Lee Quote Link to comment Share on other sites More sharing options...

landyliam Posted July 26, 2009 Share Posted July 26, 2009 is the mot failing issue only due to he seatbelt mounts? if so can i bolt my mounts somewhere else (no not the axle ) i can live with my sandwiches falling out the large holes starting to appear in the floor Quote Link to comment Share on other sites More sharing options...
Aragorn Posted July 26, 2009 Share Posted July 26, 2009 The other issue is the body mounts. Quote Link to comment Share on other sites More sharing options...
R Bates Posted July 26, 2009 Share Posted July 26, 2009 I've just replaced a Discovery boot floor with an alloy one and it failed the retest for it and i had to take it out and put a steel one in! It failed because it was riveted in not welded and apparently that is not an acceptable repair, there was no mention about the seat belt mounts because as stated above the mounts are on the cross member not the floor. I queried the testers reasons and he showed me a section on the computer that said to pass a test it needed to be seam welded in. Quote Link to comment Share on other sites More sharing options...
Les Henson Posted July 27, 2009 Share Posted July 27, 2009 When a new complete panel is fitted, then the method of attachment can be the same as the factory item, so spot welds are acceptable. If you are repairing part of a panel, then it must be seam welded. Les. Quote Link to comment Share on other sites More sharing options...
trogers Posted July 27, 2009 Share Posted July 27, 2009 Hi I replaced my boot floor and cross members with parts from Paddocks. I used large headed pop rivets for the cross members and Tech bolts for the edges. It passed without a mention. But I had already asked the original test centre if this would be OK and they said NO IT HAD TO BE WELDED. Seems like a dodgy area to me.

It also states in the mot testers manual that if a panel is originally spot welded then plug welding is acceptable for installation of a replacement. Plenty of discos pass mots with bolted and riveted replacement floors though. Don't know whether I'd buy one unless it was welded. Quote Link to comment Share on other sites More sharing options...

Bowie69 Posted July 27, 2009 Share Posted July 27, 2009 Cover the bottom of it with a load of sticky black underseal and how will they know if it is ali or steel, pop-rivited or welded? Quote Link to comment Share on other sites More sharing options...
audiman Posted July 27, 2009 Author Share Posted July 27, 2009 umm if I went for a steel floor then does it have to be a ribbed floor or could it be chequer plate or similar for example cheers Lee Quote Link to comment Share on other sites More sharing options...
boyt Posted July 28, 2009 Share Posted July 28, 2009 how i understand it, working at an mot station, the area that has been replaced must be welded in, if plated seam welded, or complete panel to manufactors orignal stands, you only need to replace the floor if it is within 30cm of a strucal point, either body mounting points or seat belt mounting points andy Quote Link to comment Share on other sites More sharing options...
Les Henson Posted July 29, 2009 Share Posted July 29, 2009 You don't have to use the original ribbed panel, flat or other plate would be fine. Les. Quote Link to comment Share on other sites More sharing options...
freeagent Posted July 29, 2009 Share Posted July 29, 2009 I discussed this issue with my MOT tester (landy specialist and well respected member of the winch challenge scene) back in January, he reckoned a pop riveted or bolted-in replacement would be fine as the panel itself is not structural, and the seat belts bolt through it into separate brackets. A lot of it is down to interperatation of the rules... and there are some pretty dumb inspectors out there... Quote Link to comment Share on other sites More sharing options...

That's my understanding as well, the floor isn't structural, so unless the corrosion is within 30cm of a structural point it won't even fail with big holes in it...
