lostinthe202 Posted April 16, 2009 Share Posted April 16, 2009 '96 OBW So I've got the trans out for a face lift and I'm FINALLY ready to put it back in, got some sunshine all lined up and I'm ready to rock.... except for one little detail that I forgot all about. During disassembly I broke off every one of the threads that are on those stand-offs that hold on that long heat shield between the exhaust and the drive shafts except for one and I can't find the blasted thing. Can anyone tell me what the thread of those stand-offs are so I can either make some tomorrow or order them in time for this weekend? Thanks!

lostinthe202 Posted April 17, 2009 Author Share Posted April 17, 2009 Weeeeelll, By some miracle of miracles, I was able to pull a stud out of the chassis side of the vehicle. For anyone not familiar with these, they are basically a coupling nut about 30mm in length with a stud on the chassis side and a stud on the heat shield side. So the coupler acts as a stand-off for the heat shield to put it where the subaru engineers decided it needed to go. The heat shield is then held on by nuts. All of my nuts were rusted solid as they haven't been used in awhile..... bada boom! (hehe) anyway, I soaked them but they still snapped. Now that I know these are comprised of a piece of all thread and a coupler, I'm not surprised. All-thread is almost always made from soft steel so it's no wonder they just sheared off with hardly a twist. Initially I tried to get one of the couplers off the car and I sheared that off as well leaving the stud inside the chassis. So i was reluctant to try removing any of the others lest I shear them all off and find myself having a jolly old time with the various methods of removing busted bolts. Anyway, I got one of the couplers to come out and identified the thread as M8 x 1.25. I had some 1/2" hex rod kicking around work so I drilled and tapped those and I'm going to pick up some M8 x 1.25 bolts from my local hardware and cut the heads of to use as the studs. I'll get some nuts at the same time, never-seize the poop out of the whole shootin' match, and I'll be ready to go. Sorry to ramble on, but this thread is so lonely, thought I'd keep myself company!

Olnick Posted April 17, 2009 Share Posted April 17, 2009 Sorry to ramble on, but this thread is so lonely, thought I'd keep myself company! Will- No! No! I'm here and I've listened to your every word! Really, I had no idea how heat shields are attached. Just know that the little nuts & bolts are always rusted solid. So I marvel at your mechanical understanding and your industriousness. Keep it up--and keep reporting on it. I love it! Link to comment Share on other sites More sharing options...
lostinthe202 Posted April 17, 2009 Author Share Posted April 17, 2009 Aw shucks, I wasn't really riding the pity horse, I know it's kind of an obscure thread to be asking about. I would've been pretty surprised if someone was like, "hey I happen to have a bunch of those stand-offs in my right pocket and a metric thread gauge in my left!" But one can always hope! Posting here is generally easier then trying to get remove rusted threads and then identifying the remains. Thanks for the kind words though!

idosubaru Posted April 17, 2009 Share Posted April 17, 2009 i saw it too late, but while reading the first post i was thinking 8 or 10 x 1.25. nearly all subaru threads are 1.25, with the exception of the really tiny stuff of course (which are 1.00). and the huge stuff might be 1.50 - like the crank, but i'm not sure. but all the average bolts are 1.25.

lostinthe202 Posted April 17, 2009 Author Share Posted April 17, 2009 That's good to know. I deal with UNC/F stuff all day long and I can usually ID them by eye, but I'm not that gifted with the metric stuff, except for the heads of course!

lostinthe202 Posted April 18, 2009 Author Share Posted April 18, 2009 Weeeeelll, once again I out thunk myself. I spent about 1/2 hour trying to tap those spacers I made to replace the busted stuff mentioned above. The only cutting fluid I had at home is some sample stuff I got at a machine show a few years back and it suuuuuuuuuuuucks. The tap was grabbing like crazy and it really shouldn't have, that steel machines really nicely. And the tap I had was not long enough to cover the 30mm stretch from one side so I was tapping in from both sides. I'm on my fourth side when the thought occurs to me, why am I not just drilling these as a through hole for the m8x1.25 and just using them as a spacer???? Doh!!! So I drilled them all out and stuck the heat shield back on in a fraction of the time:banana: The moral of the story? Maybe when something breaks you don't have take the replacement literally!
