Just put the "new" trans in. Fired it up...not bad, then..........GRRIND--SCRAPE-VIBERATONS----(Nasty Word(s) Blocking Has Been Applied!)
Started checking..Trans sill in truck..yup....Drive axels on ground....nope....ummmm....WTF!
Noise from bell housing..pull starter....hand turn engine....
OH >>>>>(nwbhba)[see above]
ALL the flipping flywheel bolts are loose and are chewing on the bell housing.
Can you say..................Well, I did!
Did I turn in the bolts a turn at a time? Yes. Did I torgue to spec? Yes, 20 ft#.
Did I check? HelK Yes!
Bently does not mention using Loctie on the flywheel bolts....What you all think? Blue? or Red?
Thanks All!
-
It is blue, they are 1 time use IIRC and it is something like 40ft/lbs plus 1/2 turn or 1/4 turn or whatever. Might have even been the 20ft/lbs plus 1/2 turn. The clutch kit I got came with the bolts and blue loctite.
-
IMO, thread locker is a must for flywheel-crank bolts on any car.
I would even use the red, and proper hardware should be used as well.
-
First we need to clarify what bolts you are talking about and what tranny this is. 020 or 02a?
If it's a 020, are you talking about the bolts that go into the crank? If so, they are one time use and get torqued differently than you described.
If it's a 020 and you are talking about the bolts that go into the pressure plate through the flywheel, they do not get thread locked (normally) I thought they got torqued to around 35 ft/lbs though. All my Bentley's are packed up so I can't double check.
-
In the Bently I have the only spec for the torqe is 20NM(15FT. LB.)
No mention as there is with the P Plate to Crankshaft of any threadlock.
Are the 9mm 12pnt different? Are these one time use?
-
Oh man that brings back nightmares from a year ago.
Were you able to stop the engine while it was grinding or did the engine come to a stop on its own.
Have you dropped the tranny to see what is actually going on in there? It could be real bad like happened to me where it wasn't the flywheel bolts, but the pressure plate bolts backing out, snapping off and coming to a dead stop when everything jammed up and machine my crank nose :(
After my experiences I loctite on the flywheel bolts after cleaning them up and reusing, the torque is low.
The pressure plate bolts, use new and I also added some loctite even though the new ones come with that blue stuff.
I also initially followed my new old clutch kits instructions with torque that said 22 ft. lbs and 1/4 turn, but later on I used the 54 ft. lbs number and 1/4 turn and it has held for 20,000 miles on my car with damaged threads in a few of my crank holes, one halfway wollowed out! I will get a new one when I rebuild the engine and am surprised the car is still on the road :)
-
To be exact, Flywheel to Presure Plate Bolts (9 of them,12 pt suckers). Some of the sites that I have looked at say "one use", some do not. Will check local sources when the sun gets up ( around 8am). If not here,...............reuse with red I guess. This is on my work vehical, so can not be down for much longer.
Thanks for the help.
-
IIRC all of those bolts there are supposed to be a one time use. The way you had described earlier I thought you were talking the pressure plate bolts, so disregaurd that last post. I used blue on mine and reused them 2 times. I cleaned them on a wire wheel to new looking each time and brake cleaned them before putting the threadlocker on. I torqued to 35 or 40ft/lbs...the bolts are close to 1/4" diameter and should be able to take that torque as if I figured correctly that would make the axial "clamp" force to be 11200 lbs and even a grade 2 bolt would handle that.
-
They are one time use, cough cough. I suspect most of here have reused them successfully. The torque on them wasn't a whole lot nowhere near the 35 and up noted in the above posts the 22 sounds close but iirc it was actually more like 12 or 15, 15 sounds correct in my head with no turns 1/4 or 1/2 or any crap. Also a key element is make sure your dowel pins are correctly aligned and in the corresponding pp notches when you torque it. I have never even seen one come loose!
-
Called my Boss, looks like I have the whole week off anyway. When your the last contractor in underground, you have to wait for EVERY one else to get done.
Ended up at the Stealership. 5 bucks for the PP/crank bolts, 1 for the flywheel bolts.
Should get them about 3pm. About same mony to order from Internet, just here NOW! (always a consideration).
Thanks for the help and thoughts.
New thead for oil pan bolts that keep backing out?

Good God that hurt reading
i saw a kid push a dowel pin thru a bell housing after a tranny on a new mazda once, but got lucky and we just smeared RTV over it and sent it
on to the meat.
iiiiiiiiii .. probably woulda hit it all with a gun.. lightly at least.
but, alldata says.. a bunch of conflicting things.

hope a few screen dumps helps
i can find text to describe "3/8ths inch IR impact" a few times
-
Oh.......................fipperduckeis.................... :-X
Would have loved that info Sunday night.
Any way . . . .All my BAD....Did not get the dowel pins in correctly...one in, one out...Bad!
Chewed a less than 1/8" groove in the bellhousing.
Will use new bolts with Blue Loctite and 44 ft lbs + 1/4 turn.
And but the trans back in in the morning.
Thanks you all.
-
My bad again................44 + is for the CRANK bolts.
I got the flywheel bolts up to 25 ft lbs and they felt right, used blue locktite on them. We will see when I drive it tomorrow afternoon. Gods I am tired of lying under the car right now.
-
wait a minute. I just put my flywheel on using the 22ft-lbs + 90 deg like bentley says. Should I tear it down and replace the bolts?

What parts are you talking about??
On our 020 tranny the flywheel is attached to the pressure plate which is attached to the crank.
If you torqued your flywheel bolts that much beyond torque, and then did another 90 degrees I would think the small bolts would have snapped.
If you are talking about the pressure plate to crank bolts then use me as an example of what not to do! If it were me I would yank the bolts, buy new and start over with correct torque. I also added a dab of loctite just in case, as I was freaked out. Here I am 20,000 miles later and its all held.
Somebody smarter than me might tell you a trick that might work as far as end result torque value or hitting them with an impact but I cant guide you on that one.
-
Maybe this should end up as a sticky of what not to do.
Clarification:
N 902 061 03 M10x1x19.5 (These are sholdered) Comes with Blue Loctite Stripe P Plate to Crank Bolts 6 needed
N 100 134 01 M7x40x20 (These are 12pt 9mm heads) No Loctite Flywheel to P Plate 9 needed
Crank Bolts are big fat suckers, Flywheel Bolts are skinny long ones.
And my bad agaain...25 ft lbs on Lubricated bolts is more like 30 + ft lbs on dry bolts....Yep, over torgued them sukers. :'( So Autohaus AZ to the rescue. Should get new bolts come Fri morn..............Gods I hope!
Will get this right (lol) ...........well..........heck yes!
Thanks for all the help!
pps: Check broke vw for neat trick using combo wrench and bolts to "lock" the P Plate to loosen/tighten those 6 bolts
-
funny, I bought 9 of the long skinny ones but only needed 6. Mine is a 91 jetta TD.
-
190/200mm clutch uses 6, 210mm clutch uses 9!
-
190/200mm clutch uses 6, 210mm clutch uses 9!
the 210mm on my TD originally had 6.. only the later 210s had 9 bolts. from what ive seen atleast..
-
Durn!...Got Caught! ;D .......Clutch package out of a 2.0 Jetta .... And yes, it is a 210 mm. 8)
-

I didn't think the 1.6TD ever had a 210mm. All the 210mm I have seen have been 9 bolts.
-
IMPORTANT INFO!!!!!!!!
Just got off phone with Loctite, and:
1) You can use Red on either side of the blue that is already applied to a bolt.
2) IT DOES act like an "oil type" lubricant. If you want 15 ft lbs, torque to
between 8 and 10 ft lbs. I do not think this applies to the pre-applied.
Bolts will (hoping with crossed fingers) be here on Fri "by end of business day". Or when the UPS guy dropps by.
Will keep you all in the loop.

i could be wrong. maybe they did only have 200mm clutches.. would make sense as to why my plate only had 6 bolts..
-
UPS guy got here, got the bolts in. 22 ft lbd does not seem like a lot, its that 1/4 turn that REALLY tightens things up. A little blue and 10 ft lbs later, the flywheel is attached. Trans goes in come morning.
Hummmm, gots us some snow coming down now.....what joyfull fun this could be!
Thanks once again to all of you for your help.
-
Okay, First........
THANK YOU ALL!!!!!!!!!!!!!!!!!!!!
Actually that's it.
Got the trans in, everything hooked up (Except the backup lites) and crusied......NOT! :o.
Gone are my 1, 3, 5 shifts......25mph in fifth....not so easy now....Which is good....might be able to get better than 30 mpg.
Okay, the trans I took out was an FK close ratio...I thought I was going to .....ummm you know....ummmmm . Anyway that idea fell through. So I am back with an FF. Kept the short(ish) shifter stuff.
Once more with feeling........
TANKS ALL!!!!!!!!!!!!!!!!!!
