jtt220 · 03-09-2004, 08:09 PM

drill a hole in the remaining stud and use an easy-out.

Red · 03-09-2004, 08:19 PM

If all eles fails refer to the book... FSM I mean.

And buy new bolts

zero.counter · 03-09-2004, 08:29 PM

"SR20DET's are GAY", sorry...I couldn't help it.
Good stuff here...

Also, here... , and check these bits out here. .

You can actually visit any auto parts store and get a bit set there to do so.

mistaanime · 03-09-2004, 09:44 PM

man..suxs to have the bolt break..juss use the reverse drill bit (easy out)to take out the broken bolt..like jtt220 said..but..shiet..if you think SR's sux..i'd gladly trade you my KA24de for the SR...lol

hey man. dont think im just some punk highschool kid talking out of my ass. i have the FSM and i DID use a torque wrench. and the bolt broke. i definately didn't torque the bolt too much because i went up in small increments. i just thought it was strange that it broke w/ less than 80 ft lbs of torque. either way sorry if i sounded harsh. didn't mean to cuz i fully understand that most high school kids are fags who dont know shit about cars. im surrounded by them from 8am - 2 pm monday through friday. thanks for the help to everyone else. one more question. wat would i do if i stripped the threads where the bolts go? would i just have to re-thread it?

240Stilo · 03-10-2004, 12:17 AM

Haha....I remember that happened on another SR I helped put in and it ran well with one broken bolt. He did a drift event about 5 hours later. We were working on it until early next morning to make sure he made it to tech

.

nightwalker · 03-10-2004, 12:36 AM

tap and die set then. Used for extracting broken bolts.

DuffMan · 03-10-2004, 08:51 AM

I dont really see how that would be possible unless:

1. You over torqued the bolt. Dont remember what its supposed to be off the top of my head, but its not 80ft lbs.

2. The bolt was extremely rusted, and you should have replaced it anyways.

I can understand maybe breaking one if it was stuck and you were trying to get it off, but torqueing it down, that just doesnt seem right to me.

mistaanime · 03-10-2004, 02:41 PM

eh....I broken a caliper bolt but got another one and got it fixed..bought the bolt at nissan for 8 bucks..oh well

shiet happens..thats life.

the torque setting is 105-112 ft. lbs. i was going up in increments and as i was trying to torque it at 80, the bolt snapped. who knows? well im gonna try to use that easyout today. i appreciate your help guys.

DuffMan · 03-10-2004, 08:31 PM

Whaaaaaa?!?!?

Haha, no wonder it broke, those bolts are tiny.

Ok just checked the FSM the proper torque is 25-33 ft lbs.

Oh wait thats the flywheel to clutch plate, is that not what you meant? My s14 fsm says 94-101 ft lbs.

nismo2491 · 03-10-2004, 08:45 PM

duff- you are talking about the clutch to flywheel bolts. the little ones that hold the flywheel to the pressure plate. I'm more than sure they are talking about the crankshaft to flywheel bolts. the ones in the middle of the flywheel, the big ones

Not to start a shit match but you not liking "highschool punks" has nothing to do with cars and doesnt need to be here. Just for your info I managed to change my flywheel without breaking any bolts while torquing them down

Its called replacing the shitty nissan bolts with a higher grade bolt like myself. Apparently your lacking common sense knowing myself how to get a broken bolt out but I guess thats just because my father is a machinist

ae86andrewcrew · 03-10-2004, 10:15 PM

ermmm ok. didn't think i'd really strike a nerve w/ anyone but ok. there's plenty of people on here that say things a lot harsher than i do and they dont get any beef. it just sounded like nightwalker's response sort of made it seem like i was just some dumb kid, but judging by his other response i think i just overreacted and thats why i made sure to include that i hoped i wasn't trying to sound too harsh.but yea watever man. sorry i lack the common sense that you were gracefully endowed with mr. machinist. how was i to know that nissan used such "shitty bolts" as you called it.

everyone helped me out a lot and i thanked them. wats the point of YOUR post?

LOL This is really stupid...I think you need to take it easy man. No reason to point out people in highschool thats all I was saying. The point of it is is this is a car forum not a stupid highschool punk forum. I'm here to help anyone just as much as other people are...You have a problem with it I'll help ya...If you decide to re-thread it (tap) make sure you drill a block and use it to make sure the tap is going in straight and you dont mess the threads up...if you do you can get a reamer and ream it out then get a bigger tap and just change the bolt to a diffrent thread pattern.

mistaanime · 03-10-2004, 10:26 PM

lol...ae86 doode..this fourm is free speech..juss don't take shiet personal..

ae86andrewcrew · 03-10-2004, 11:54 PM

yea i got you guys. no hurt feelings here. but you're saying its a free speech, yet i can't say what i want to say either? ehh forget it. i got all the info i needed and i still appreciate all the help. thanks

LOwrestling2k1 · 03-11-2004, 11:21 AM

where do u get these "higher quality" fly wheel bolts...anyone have the specs on them? (thread, pitch, length). thanks

If you take one of the bolts to a hardware store im sure someone there can tell you and if they dont have a better bolt you can just get the info from them and search online for a bolt store like boltdepot.com to get the bolts.

nismofeind · 03-11-2004, 03:28 PM

Your making a very big assumtion that Highschoolers don't know anything about cars and are dumb. Kinda pisses me off to because I'm in highschool and I probly know more about cars than half the people I talk to. (whatever its your problem)
Most of the time one can feel when a bolt doesn't want to go in and about to break, especially when it shouldn't be very hard to turn at 80ft/lb's. I usually stop clean it then try again or replace it.

nismo2491 · 03-11-2004, 04:38 PM

dude he said high school punks don't know anything about cars. if you're not a high school punk and are just a high schooler you are cool.
there its ended. back on topic

The point of it is is that it shouldnt have been said to start off with but yes...back on topic, this is becoming quite stupid.

Ryan of Velocity · 03-11-2004, 08:01 PM

Broke the heads off flywheel bolts a few times in my life. Usually it's an easy out though. If you take out all the other bolts and yank the flywheel off there's usually enough shaft on the broken one to get a wrench on and unthread it out.

Eternal_240Sx · 03-11-2004, 09:53 PM

omg the exact same thing is happening to me rite now!! i was using a torque wrench to torque the bolt down at 85 ft. lbs. when the head of the bolt just broke off.. ae86andrewcrew was the easy out successful? also i bought the bolts from boltdepot.com. I think i should go with nissan bolts but dont know what the part number is. Can anyone help me?

ae86andrewcrew · 03-11-2004, 09:58 PM

yea ok i didn't think it would elevate like this. here's my formal apology to all you high school punks. I APOLOGIZE. anyways.......... yeah well i took of my flywheel w/ my new easy out and ready to start drilling, but then i saw the broken bolt and it just twisted it out. eh watever. well now you guys have persuaded me to replace all my bolts now. any info on where i can get these "heavy duty" bolts would be GREATLY appreciated. i promise i wont talk shit about high school kids anymore. i checked out local nissan parts centers and they dont have any in stock. i was thinking about hardware stores, but im not sure if they'd be ok to use. well i dont know. i guess the easiest way to sum up all my random ass questions is........."what did YOU guys do for YOUR sr20's when you installed it? did you buy new bolts? and from where please?" well i appreciate the help again. peace

did you take off ur flywheel to check the bolt? if not, just take off the flywheel and try to twist it out. i think the easy out would be very useful if the bolt broke off deep into the thread, so that it would be inaccessible (spelling????), but if the head broke off while torque'ing ur flywheel down, i think there might be some space to grab it w/ vicegrips of something.

Eternal_240Sx · 03-11-2004, 10:17 PM

yea.. thats what i thought too. i bought some visegrips just today and tried to twist it out, but to no avail...the only thing it did was damage the bolt. Do you think should just sand down each side of the bolt so i might be able to get a better grip with the visegrip?

When i started replacing bolts on my car I went with titanium bolts but a high grade steel bolt will work just fine...I know boltdepot.com has some nice bolts. I'm not sure what grade bolts Eternal_240Sx got but I do know alot of the bolts on the 240 are grade 6 wich if you look up is not made for automotive use. You can go with a 10.9 grade and I can assure you wont have any problems breaking them. But I would highly suggest to both of you to not only replace all of the bolts but to buy a tap and run it through the threads to make sure the threads arn't damaged and to make sure its all clean in there but be sure to drill a straight hole in a block to use as a guide so you dont break the tap in there and/or mess the threads up. Be sure to go slowly with it and use oil or some other sort of lubricating while usuing the tap! Hope that helps! Oh and apology accepted lol jk jk.
