Torque setting for pressure plate bolts (Textralia)
I'm currently installing my Textralia Z-grip and i'm now in the process of installing the cover.
Does anybody know the torque setting of the pressure plate bolts?
I've read 23ft/lbs and also 55ft/lbs.
p.s.
a high end 1400$ clutch and not even an installation instruction included.
It's pathetic.

55 lbs/ft will work and make sure you put red loctite on the threads.
I forgot to add, this is a great clutch, mine has been if for 4 years and has hads tons of abuse and is still going strong,,,,just make sure you break it in properly! That's the key to making this clutch last and work the way it's supposed to. There have been a bunch of complaints about the Tex 0Z700 on this forum, but I suspect that the problems were mainly caused by improper break-in.

Thanks,
i have those tightening specifications, however the bolts are not the same as stock GM bolts, i'm unsure if the same torque settings apply. I need to be sure.
Also tightening the bolts in 4 passes with locktite applied looks pretty impossible, there is not enough time before the locktite sets.

Also, if we do not know what type of bolts you are using, how can one recommend a torque value?

Bolt torque is determined by bolt size and material being clamped together. If the bolts are the same size as the OEM and I would assume similar material the same torque spec would be correct.
#7
Here is a link to a chart that deals specifically with bolt grade and material. There are other charts that will deal with material being clamped together, for example aluminum to steel. Baldor used to publish a little pocket book that had those handy numbers for electricians working on switch gear bus bars etc..

...and "assuming" is how people make mistakes. Also, the type of lube, loctite, etc....also determines what value a bolt is torqued to. I like to have all the info.....but..to each their own.

Well if you'd like to do some further evaluation and a bit of math consider the information found at this link.
http://www.loctite.com.au/cps/rde/xc...0_AUS_HTML.htm
The factory manual does not specify what condition the torque spec applies to. If it were me I would determine my bolt grade and size. Look it up on a chart to determine if the torque spec matches the dry or lubricated column then apply the factor loctite recommends at the link above if the torque spec appears to be for dry.
If I were from France I would test my bolt torques using this method: http://www.guba.com/watch/3000009652

You should have instructions with the clutch. Mine were:
75 N·m with Red Loctite, or 55 lb-ft
I did mine in steps on my back with a flywheel wrench to turn and hold the flywheel. Not a lot of fun but doable. Biggest thing to know in advance, your motor will be loud when you re-start because all the lifters will have bled down after rotating the flywheel so many times. Also, there is a torque pattern. Number the pressure plate per the pattern, makes it much easier to keep track of your steps.

55 lbs/ft will work and make sure you put red loctite on the threads.
I forgot to add, this is a great clutch, mine has been if for 4 years and has hads tons of abuse and is still going strong,,,,just make sure you break it in properly! That's the key to making this clutch last and work the way it's supposed to. There have been a bunch of complaints about the Tex 0Z700 on this forum, but I suspect that the problems were mainly caused by improper break-in.

As far as breaking it in, just do alot of city driving for the first 500 miles or so, lots of up and down shifting, no high rpm power shifts or hard launches, that's what I did and it worked out fine.

Yes i think i have ARP fastners as well, i will check tomorrow.
Anyways i called textralia Australia just a minute ago and i got an answer from them: 55ft lbs for the cover bolts with locktite.
Idiot me i called them at 5 in the morning without thinking and they actually picked up the phone. oops
for your information the previous information (25 ft lbs) came from vengeance racing.
This is their website by the way:
http://www.texracecars.com.au/textra...iscount_coupon
australia dialing code is 61
I think we can conclude it is 55 ft lbs
Tomorrow the Z is going back together, my ECS brace arrived as well

My Tex clutch came with ARP fasteners and the info sheet stated to torque the pressure plate bolts to 55ft.lbs.
