Turnips 3 Posted January 10 Share Posted January 10 Evening, Rivnuts - or to be precise: rivnut removal. I am currently stripping the bulkhead on my 109 prior to shot blasting. Of the four rivnuts on the bulkhead (engine side) two are spinning. One of them will be an easy fix, I'll just nip it up with my rivnut tool. The other is going to cause me a headache as I had to cut the bolt head off to remove the heater matrix. What are people's preferred solutions to this? Quote Link to post Share on other sites

Stellaghost 516 Posted January 10 Share Posted January 10 As above but I would use a die grinder or drill with a small bit in it so you can weaken the rim and less chance of damaging the parent metal regards Stephen 1 Quote Link to post Share on other sites
Turnips 3 Posted January 10 Author Share Posted January 10 Thanks for the replies. Yes my worry was that I didn't want to dig into the metal on the bulkhead with whichever disc on a six inch grinder, and I can't drill it out as the rivnut just spins in the hole. Die grinder is going to be the right tool for the job here I think Quote Link to post Share on other sites
landroversforever 877 Posted January 10 Share Posted January 10 Sometimes with the smaller rivnuts you can squash the lip inwards with a pair of pliers too. Quote Link to post Share on other sites
Turnips 3 Posted January 10 Author Share Posted January 10 Good idea, hopefully I'll get time to have a look tomorrow night. I'll let you know! Quote Link to post Share on other sites
simonr 291 Posted January 10 Share Posted January 10 I've found a cold chisel (plus hammer) will deform it enough to hold position while you drill it out. Same principle as the pliars - but more satisfying! Quote Link to post Share on other sites
L19MUD 270 Posted January 11 Share Posted January 11 No help now I know but when I drill a hole for a rivnut, before fitting it I use a 3 sided file to take a small triangle of material out, when you clamp the rivnut up it jams into this void which is usually enough to stop it spinning when you need to undo it later on Quote Link to post Share on other sites
Stellaghost 516 Posted January 11 Share Posted January 11 How simple and clever, thank you will be trying that regards Stephen Quote Link to post Share on other sites
Romahomepete 25 Posted January 11 Share Posted January 11 A slight drop of superglue rountd the edge may stop it frpm turning sufficient to drill it out. Peter Quote Link to post Share on other sites
Turnips 3 Posted January 11 Author Share Posted January 11 Thanks for all the input. One solid hit with a chisel and the rivnut popped right out! Quote Link to post Share on other sites
