GTO Slave Cylinder Replacement

Why are you torquing tiny bolts like that? I don't understand people's paranoia. All you're doing by pulling out the torque wrench is giving yourself more leverage to break stuff.

Also your flywheel looks pretty terrible. Those colored spots are typically harder than the metal around them and will cause vibration/chatter and such down the line, if they aren't already.

Really wasn't' thinking about the size of the bolt vs 18 ft lbs. Afterward I realized they're pretty thin for that. They are flanged hex bolts so I figured thought they were higher grade. Had I known the right torque spec, would have been fine.

Stop it.

Seriously, unless you have a small torque wrench I wouldn't bother at all. Something like this: http://buy1.snapon.com/catalog/item...roup_ID=675233&store=snapon-store&dir=catalog

For the record I've made the same mistake before and snapped a bolt. Luckily I now have access to a set of wrenches similar to what I linked.

$340 clams for a small torque wrench? Whoa. Silver plated I hope!

Point being, a common click-type wrench is usually rated for 20-100ft-lbs. lets say. I would not rely on it at 20 ft-lbs. Short of having specialty torque wrenches I typically use a 1/4" ratchet (short) and call it good.

Good post.

How about you piss off?

Taking notes Adam? Or have you already swapped your clutch?

So today the fun continued. New oil pan bolt came in yesterday so I could finish it up.

The offending bolt

Oil Seal cover back in and tightened down

New flywheel, bolts torqued 15, 37, 74 ft lbs

Clutch disc

Pressure plate 52 ft lbs

Bellhousing back on, 37 ft lbs

New slave cylinder w/remote bleeder, had the spring off to measure for the shim.

Slave in

Tranny in

Tomorrow's to do list:

- finish torquing the transmission bolts
- reconnect the wiring
- bleed the clutch
- re-install driveshaft
- re-hang the catback
- bolt up the cats
- test clutch engagement
- take off stands and test drive

You get a full pass on that broken bolt. Some engineer needs to stab himself in the stomach for that. 'Foot long M5 bolt? Sounds like a good idea to me!' D:

Hehe, thanks. Yeah definitely a strange bolt for an oil pan.

So for anyone following this the goat is all back together. New clutch and slave are working well and no oil leak from the crank seal so mission accomplished.

I will say the Spec stage 1 is definitely gives a stiffer pedal than the stock. Have to push twice as hard now on the pedal. It grabs a lot lower down on the pedal travel too. I'm sure as it wears that will change. I've also got some shudder at low rpm engagement but I guess it will do that as it breaks in? This seems to get better as it warms up and I drive it. It definitely grabs hard and feels snappier when it engages which is definitely fun.

Next project Russell stainless braided brake line install. Should help make that middle pedal a little firmer. Stay tuned.

Blarg, I hate hard clutch pedals. If the factory didn't provide enough mechanical/hydraulic advantage, stiffer pressure plates are a no-go for me. Does anyone make a modified clutch master, perhaps?

Make sure you bled it well enough. Engaging/disengaging close to the floor would be a sign of air in the system, in general. Is the pedal effort somewhat consistent, or is it kind of soft at the top of the travel?

Does feel softer at the top. I can bleed it some more and see if it improves. Think that's it? Maybe it's still got some air in it.

Tick performance does make a heavier duty clutch master which could be an option.
