nosandbeck Posted February 21, 2015 Share Posted February 21, 2015 I have been given a Mantec 115-RAIDEF Raised Air Intake for my 63 plate Defender 110 Utility. Whilst the majority of it looks straightforward and a post by White90 shows some useful pictures, how do I get the pre-threaded bolt retainers into the wing with a rivet gun? I've never used one but surely they are way too big? Any help would be gratefully received from this Defender relative-newbie. Quote Link to comment Share on other sites More sharing options...
landroversforever Posted February 21, 2015 Share Posted February 21, 2015 I've not fitted one myself, but I think you're talking about rivnuts or nutserts. They need a different tool to normal pop rivets, however with care they can be done with a bolt. wind a nut right onto the correct size bolt add a washer or two. Then screw the bolt into the rivnut so you have full thread engagement in the insert. Then you can turn the nut to pull the rivnut up tight. Where abouts are you based? there might be a member with a rivnut kit nearby? Quote Link to comment Share on other sites More sharing options...
nosandbeck Posted February 21, 2015 Author Share Posted February 21, 2015 Thanks a lot - I thought I was going mental! Based in Shropshire near Bridgnorth but will ask about and see if anyone has one. Quote Link to comment Share on other sites More sharing options...
Simon Smith Posted February 22, 2015 Share Posted February 22, 2015 I used to use the nut and bolt method, but since owning a rivnut gun I can't work out why I didn't get one before. Quote Link to comment Share on other sites More sharing options...
Anderzander Posted February 22, 2015 Share Posted February 22, 2015 I had the tool - but it just does upto M6. I've just tried to put an M10 half hex nursert with a bolt and it didn't go so well. I think the hex in the crossmember has rounded out and the nursert feels like it won't compress anymore even though it's not tight. I think the oversized nut and the washers stopped spinning. I've done it ok in the past ok - though that was wish nursert that were easier to compress. I've cleaned the washers up and greased it all and will give it another go to see if it will fully pull it down on a second go.... Quote Link to comment Share on other sites More sharing options...
Happyoldgit Posted February 22, 2015 Share Posted February 22, 2015 Aye, once you have a decent rivnut tool you'll wonder why you hadn't bothered with one before Quote Link to comment Share on other sites More sharing options...

studmuffin Posted February 23, 2015 Share Posted February 23, 2015 I live in Bridgnorth and have a Kennedy Pro Rivnut tool which does M4 to M10. If you prep everything you are more than welcome to pop around to fit them. If so PM me. Cheers Barry Quote Link to comment Share on other sites More sharing options...
Snagger Posted February 24, 2015 Share Posted February 24, 2015 I have the smaller type gun that does up to M8, though it's a struggle with over M6. The bigger tools are pretty expensive - typical prices for a bolt-cropper shaped type for M10 and a bit more is about £130+VAT. Quote Link to comment Share on other sites More sharing options...
Mo Murphy Posted February 24, 2015 Share Posted February 24, 2015 I can't help but feel that anything heavy enough to require an M10 bolt should really be nut and bolted. Mo Quote Link to comment Share on other sites More sharing options...
Snagger Posted February 24, 2015 Share Posted February 24, 2015 Sometimes it's just convenience. When I recently had to replace the knackered nutserts that secure the steering column bracket tot he front of the bulkhead, M10 rivnuts would have been the right diameter for the holes, even though the old bolts were M8 equivalent. In the end, I had to make a steel plate with M8 rivnuts and insert it from the open end of the bulkhead section near the wing and use welding wire to drag it along into position. Rivnuts that size allow plenty of torque on the bolt without stripping the threads. Quote Link to comment Share on other sites More sharing options...
Anderzander Posted February 24, 2015 Share Posted February 24, 2015 Sometmes it's the fact it's going in blind. Like the crossmember box section - no crush tube or access to the rear means no alternative ? Quote Link to comment Share on other sites More sharing options...
Mo Murphy Posted February 24, 2015 Share Posted February 24, 2015 What are you bolting to your cross member that requires M10 Stephen? Quote Link to comment Share on other sites More sharing options...
Anderzander Posted February 24, 2015 Share Posted February 24, 2015 A rear step. One of the bolts I could get a nut too one I couldn't ..... Isn't yours a Td5 chassis with a rear step ....... How is yours fitted ? Quote Link to comment Share on other sites More sharing options...
Mo Murphy Posted February 24, 2015 Share Posted February 24, 2015 M8 inserts, I think. I'll take a look in the morning. Quote Link to comment Share on other sites More sharing options...
Anderzander Posted February 24, 2015 Share Posted February 24, 2015 They may be M8 actually ..... I'll check too. Quote Link to comment Share on other sites More sharing options...
