sorry for posting this here but i thought it would get more responses here from those that might be able to help.

i am in the process of installing my JWT Clutch and flywheel, and everything is going good, when 2 of the 9 bolts that attach the clutch plate to the flywheel completely strip. they go in straight and easy, not crossthreaded, and im not even putting force on them and, the bolt "pops" and the threads are toast. the other 7 are fine, i tqd them down to specs. on the 2 that stripped there was still about half the thread left in the flywheel, so i took off the washer and screwed them in. they are tight but im afraid to really tq down on them.

what would you guys do, trust the 7 that are correct and not worry about the 2 that "may not be tight enough" or put the GDMFing stock parts back on and chalk this weekend up as a total loss.

i could just use the stock flywheel with the JWT clutch.

 

Why can't you just re-use two of the stock ones?

 

the threads in the flywheel stripped out, f0ck it, im gonna have it towed to a shop monday. damn.

 

I would just use the stock flywheel with the JWT clutch and call it a day. Still grabs hard, and much easier to drive with.

 

hmmmm. if the bolts are across from eachother, i would retap the holes to a larger size. only if they are across from each other though. pretty important to keep balance though. maybe a helicoil could work for ya. i dunno, were the threads messed up at first? trying to help out with ideas, but dam, that sucks!!!

 

They sell a tool, that will re-thread it for you

 

you know how the clutch plate has 3 sets of 3, it was 2 in the same set so they are right next to each other. the threads seemed fine before i put the bolts in, they went right in easy, it seemed like once the threads started meeting resistance from the clutch plate, they just popped out, because when i pulled the bolt out, the threads were still on the bolt.

but it was only the first half of the thread, i just took off the washer so i could get in deeper, and screwed it in anyway. i got it pretty tight but i didnt want to really tq down on it.

im gonna have to get the car towed to a shop to have them reinstall the tranny, my tranny jack broke and i cant get the tranny back in, so now i have to get it towed there, have them install it, then have it towed back, so i can reinstall teh turbo stuff. this is the first time ive had to surrender to the mod gods for assistance.

 

those bolts have got to endure a lot of load - i wouldn't trust any kind of insert, especially since this is a brand new flywheel. i'd expect JWT to replace it, but that might be tough - obviously, they are going to say you f0cked it.

were you on the stock items before? were you having slip?

ahm

 

well i actually bought the flywheel used. i doubt they would replace it, and i cant really wait on a replacement, this is my daily driver and i needed to have it done before tomorrow. now ive gotta take a day off work and get it fixed.

my stock clutch was slipping after 2 runs at the track. when i removed it it had several hot spots.

 

Tig everytime i read a post it makes me realize that its just not my car karma thats bad.Replace fw or put stock back in until u get another.Way to much load on those ecspecially if in same section.

 

yeah youre probably right

 

Best to do is install Heli-Coils in ALL 9----No big deal ---I do it all the time and sometimes even before I reassemble ---Cuz fact is a Heli-Coil is stronger and better than the original tapped hole. ---I like my JWT F/W

 

hmm, helicoil. whats that?

edit, NM, just googled it, i wonder if thats something my shop could do. so basically you tap the hole, insert the helicoil, then screw the bolt in. pretty sturdy?

 

i have used them a few times with good results. prolly gunna be the best way for you to go. even seen them used to stripped head bolt holes!

 

Heli -Coils hve been around a long time---U buy a Kit That has the correct size needed ( Metric or SAE Thread ) They come in ALL sizes. The kit contains a quantity of Heli-Coils----For example 1/2 by 20s----That is a thread thats for 1/2 inch bolts that have a 20 pitch, Meaning 20 threads per inch --- This is also called a 1/2 inch course thread bolt. This is just an example!!!! The bolts in the JWT are prob 5/16 " Maybe 3/8".
Also in the kit is a special tool for inserting The coil, A special tap for tapping the newly drilled hole. You drill the holes with the recomended size drill using a drill press, Tap the hole with the provided tap then basically Screw in the helicoil with the provided tool. The Heli-Coil is really a VERY precislly designed Stainless Steel Spring that iis threaded in the newly tapped hole --- Once its in IT CANOT BE REMOVED!!!!!!! And there u have it ---The original threads and pitch in Stainless Steel that acctually gets stronger when stress ( torque ) is applyed to it. The kits are like 25 Dollars and come with maybe 10 Coils. Anyone that is careful and knows a little bout wrenchin can install them ---Through the yrs Iv Heli-Coiled 100s of F**k ups with NEVER a failure and a great many in flywheels. Good luck !!!!! By the way ---they can be bought at any good Auto parts place. I by mine at Napa----Take a good bolt with u so they can size u right AND Id reccomend a new set of bolts from the dealer Of the correct size and Grade ---At least Grade 8 from a good supply house ---Some have a step so Dealer be best

 

Oh ----DONT USE LOC-TITE WITH A HELI-COIL

 

so this would be better than just retapping the flywheel?

couldnt i just take the bolts from the flywheel and they could use them as an idea of what size i need.

 

Well in all intent a purposes u are retappin the F/W But u are improving on the original design. DRILL---- RETAP oversize ---then the H/C brings u back down to original-stock size only stronger and imposible to strip.

 

ah, gotcha. so i can use the original bolt with the helicoil, whereas with just the tap id have to use a larger bolt.

 

KISS.......Keep it simple...........I have a 04 enth...pure stock....I am not an engineer or designer, but a driver......drive it, enjoy it, keep it clean and wait for the next exciting thing to come from Nissan. At 55 yrs old I have learned that when it comes time to trade or sell you will pay for all those options again ........you car is worth the most $$$$ in a pure stock factory condition.

Just a thought..... jafo
