Subaru_dude Posted April 29, 2006 Share Posted April 29, 2006 i took off an idler pulley to the timing belt... next to the oil pump.... to take off a piece of timing belt cover. torqued it down... probably to about 20 pounds when it got really easy to turn all of a sudden. stripped out the hole... so I drilled it out to put a heilicore in it... but when I tried to rethread it, the drill got stuck and it burned up, so I had to use a wrench to remove the bit. So I put the core in it... and start threading the bolt in with the timing belt gear on it. It gets stuck, I take it out and the threads are pulled off the bolt. AND I apparently drilled the hole crooked? didn't know I was that dumb... lol. I'm pretty darn sure I didn't cross thread it... should I drill it bigger and try again? there doesn't seem to be a whole lot of aluminum left over from last time though, that's the only problem. Could I take it to a welder and have him weld a stud in it's place? I don't wanna do that, but that's what I"m leaning towards. Thanks to anybody who has any advice.

Subaru_dude Posted April 29, 2006 Author Share Posted April 29, 2006 oh yeah.... and I used an M10 1.5...and i'm gonna have to drill it out again to put another helicoil in... what size bit should i use to drill the hole out? i'm so tired of screwing up... lol well actually, it'd be nice to do any type of screwing right now cuz I NEED TO GET THIS THING OUTTA HERE BEFORE I FEEL LIKE I'M Link to comment Share on other sites More sharing options...
Roundeye Posted April 29, 2006 Share Posted April 29, 2006 Thats bad. The Helicoil kit should tell you what size drill bit to use. You MUST make sure to drill 90 degrees to the surface. Very important. If the hole is too hogged out to fit a Helicoil, all is not lost. Remove everything near that spot and have the hole welded up. It's going to take a skilled welder to do this. Then resurface the area and drill a new hole for the bolt. I would still use a Helicoil. Good luck. Link to comment Share on other sites More sharing options...
manxsta Posted April 29, 2006 Share Posted April 29, 2006 MMMM, very sharp learning curve....weld it up dude and start over,,,,,good luck! Link to comment Share on other sites More sharing options...
GeneralDisorder Posted April 30, 2006 Share Posted April 30, 2006 Clean it all out really good - remove the helicoil too. Fill the hole with JB weld, and then file it flat - drill, heli-coil and reinstall. JB is pretty tough stuff - especially when it has something to bond to like inside that hole. Other option is to TIG weld it up and start over like everyone is saying. Personally I would at least try the JB weld first. I've seen it hold some amazing stuff.

fastenova Posted April 30, 2006 Share Posted April 30, 2006 Personally I would at least try the JB weld first. I've seen it hold some amazing stuff. Like half my intake? Yeah, try JB, drill it, tap it, helicoil, should hold pretty well. And DON'T be in a hurry. Give the JB a few hours to cure after you fill the hole, drill it, and give it another 24 hours to cure before you tap it. You should be all set. If it doesn't hold you're just out a few bucks for the JB and a couple of days. Aaron Link to comment Share on other sites More sharing options...
GeneralDisorder Posted April 30, 2006 Share Posted April 30, 2006 Like half my intake?Aaron Yeah - didn't know it would hold up to coolant pressure. GD Link to comment Share on other sites More sharing options...
Caboobaroo Posted April 30, 2006 Share Posted April 30, 2006 Yeah - didn't know it would hold up to coolant pressure. GD I did that on my intake in my RX. Had to put a fitting into the spyder passage for the turbo, so out came the JB weld to mate it all up. Works great! Link to comment Share on other sites More sharing options...
