dropped transmission, i think i found my wierd noise. looking for suggestions.

[sdtouge]

so i droped my transmission this morning, expecting/hoping it was just a throw out bearing needed replacing. all the bolts holding the flywheel to the motor have come loose. all are about the same distance out. i talked to kim, who is also using this setup with his ca, and he also had a similiar problem. but knightrider (jordan) never mentioned this. i think it might have just been a fluke for us two.

i tightend the bolts are best i could with my hands (ie no power tools, just using a socket and my hand to hold the flywheel and some locktite. guess this was not tight enough.

noticed also someslight grindage (yes i made that word up lol) on the teeth of the flywheel from the starter (its a tooth off).

basically im just wondering what course of action to take. im thinking1) take out bolts, more lock tight. air compressor in. re install everything.2) get shorter bolts (might they be to long)? they went in fine it seemed before.3)sell my soul and old setup, get either clutch masters or orgura clutch flywheel and clutch setup, and a used ca starter.

lemme know what you guys think.matt

Loctite and affix per FSM with the proper torque specs. No air.

The fsm doesn't tell the torque specs, that is for all nissan fsm for some strange reason.

I would use an air gun to tighten them and no they are not short, they got loose because you didn't tighten enough by your hand tools.

Good luck,RafIPULSAR GTR

my fsm has the torque specs for both the flywheel to crank and pres plate to flywheel

the flywheel to the crank is in the engine mech section and its 72-80 ft-lbsthe pres plate to flywheel is in the clutch section, 16-22 ft-lbs

HUM, I remember looking up the specs for the flywheel torque tightening, and I couldn't find it any where, same with the z32 fsm. I must have missed it. Which page did you find it for the ca18det ?

this is in the s13 200sx fsm

my air tool is really weak, and if i dont use it i have no idea how i can get it that tight. air gun on level 3 or 4 should be perfect.

thanks guysmatt

just use a decent sized torque wrench? thats all i did, and used a socket around a tooth to keep the flywheel from rotating

a good investment- the 10-75 ft-lb craftsman torque wrench.. i think i got it for $50 on sale from teh craftsman club, and it works fine for everything on this car/engine (it works below and above what its rated for too, i did a 6 ft-lb, and an 80 fine)

[CA19DET]

are you using a un-sprung clutch disk?? i am and the same thing happened but i actually broke some of the bolts...

[ca18detdrift]

hey Mat, was your noise the same one i described happening to me? also will you be at willow springs this week end (maybe you can check out my car haha)?

[originalsin]

tq wrench and red loctite

[CA19DET]

my solid disk clutch still rattles them loose...

i think i am going to get ARP bolts and fasteners w/ lock washers etc. i rememerb speaking to ARP and they told me that using fasteners to tighten a bolt is better as it stretches the bolt from both sides or soemthing.. i'll give it a go next time i drop the box.

[sdtouge]

you never gave me the video clip lol so i dont know if thats what noise you were hearing too. no i wont be there this weekend im waiting on a new turbo. ill be there the next jd advanced day tho. hope to see you there.

thanks alot for the suggestsions. how do you hold the flywheel from spinning why apllying so my force to it. before i ghetto riged a screw and a screw driver to hold it, but this is 10x more froce. im thinking i just have to impact it unless somoen has a way to do this while its in the car and keep it from spinning.matt

[CA19DET]

have someone hold a socket wrnech on the front pully/crank pully nut that attaches to the crank..

[nismoplsr]

I had the flywheel bolts come loose on me twice in the past. The last time the flywheel wobbled around so much it it seized my oil pump and i had to rebuild the entire bottom end.

I came up with two ideas to prevent this from happenning again.

1. drill the bolt heads for safety wire and string together all the bolts2. use some sheet metal and cut out the bolt pattern and tabs so that you can fold them up around the bolt heads to prevent them from turning loose.

I would also use brand new bolts, the old ones might be stretched, if you are not already doing that.

[sdtouge]

flywheel bolts are too long.

debating getting shorter bolts, or using washers/lock washers of that sort.

[f s t caz]

either have someone w/ a breaker bar and socket on the front crank bolt or thread a transmission bellhousing bolt in one of the holes on the block and use a long pry bar wedged between two teeth and have a friend hold it in place (using the trans bolt as a pivot point) while you properly torque the flywheel bolts.

[sdtouge]

i like how you bolded properly lol. thanks.

i just ran to the store got some new ones. it seems the 10mm x1x 25mm fine thread will be perfect, they are actually like 1.5 each so c rads deal was a good move for those who did it.

thanksmatt

edit, ca19 i just saw your post, no i dont think i am using unsprung. its a 6 puck from act, and a spec flywheel. im not sure though. ill check through ebay.
