grantmc 59 Posted November 4, 2015 Share Posted November 4, 2015 Wondering if someone might have a suggestion. On the block of my aluminium engine are 3 bolt holes, 2 of which have basically lost their thread. As a result the bolts don't tighten. I've tried new bolts with loctite and a little thread seal tape but no improvement. Ideally I would use helicoil inserts but the access would require more or less taking the motor out. Any ideas?

180S 20 Posted November 4, 2015 Share Posted November 4, 2015 We'll I guess it depends on what the 3 bolts are holding. Quote Link to post Share on other sites
grantmc 59 Posted November 4, 2015 Author Share Posted November 4, 2015 We'll I guess it depends on what the 3 bolts are holding. An alternator bracket. It's not possible to bolt that to another position. But it's not the first time I've had stripped threads in awkward positions and it was more a general question. Hoping someone might have a treasured trick they'll share. Quote Link to post Share on other sites

aklsailor 1 Posted November 4, 2015 Share Posted November 4, 2015 How about tapping the holes out and fitting bigger bolts, if there is enough access to tighten the bolts u should b able to get a tap in there ! Quote Link to post Share on other sites
Island Time 1,239 Posted November 4, 2015 Share Posted November 4, 2015 To get the full strength you had before, asfaik the only two methods are to tap the holes to the next size up, or use a helicoil. You may be able to epoxy in a stud instead, but it wont be as strong. An alternator bracket is subject to quite a bit more load than most realise. Quote Link to post Share on other sites
