Thread: Clutch M/C Question

  1. #1

    Default Clutch M/C Question

    Does anyone know what diameter the plunger is inside the clutch master cylinder on a Solstice/Sky? Or does anyone have any leads on how I might find this out?

    Thanks!

    Not too sure on this one. What's the problem? You looking to rebuild it or something?

    Should be stamped on the cyl.

    Ha you guys crack me up. No, I'm not rebuilding one, if I had one to look at I'd already know what size it is, and I'm not using one to begin with so I can't change it. LOL.

    I'm using a Solstice hydaulic clutch throwout bearing in the car I'm building and I will NOT be using the stock master cylinder. I need to know what size the stocker is so I can get the right size aftermarket cylinder.

    what ever you want. the issue for the master cylinder is: pedal stroke, pedal effort, lengthof push rod to suit the pedal stroke, diameter of pistom to determine effort....any 3/4 inch aftermarket m/cyl to suit an aftermarket pedal tray, but and its a big but, what stroke will determine if you are going to overthrow the TOB, which is why sticking with stock pedal tray and m/cyl makes your job easier building ur hot rod.

    No chance of using stock stuff at all. Pedal assembly is mounted to the chassis under the floor so no swing pedals.

    I can easily measure the stock stroke and copy that spec into my pedal design. Just need to know diameter so I have the same effort as stock. It's kinda easy when you can build whatever you want 'cause I can just make it work right the first time.

    Anyways, I'm trying to keep from buying a $60 clutch master cylinder that I'm not going to use just so I can figure out the diameter. Does anyone have one laying around?

    nope. btw pendant pedals work best for driving in brake and clutch ergonomically; floor mounted gas pedal works best for the same reason. Best person to email for m/cyl diameter is tom@crateenginedepot.com and he can also sell it to you cheep.

    I'm aware of the ergonomics, thanks. Not doing swing pedals. No room for pedals on fire wall in the driver's compartment(steering box is in the way) plus no room on the firewall for master cylinders in the engine bay. Under the floor they shall go.

    Now, going beyond the master cylinder, I also need to know about flywheels. The motor I'm using is a Saab B207R/LK9. Tranny is an AR5 out of a Colorado truck but the bellhousing is from a Solstice. The TOB that came on the Colorado tranny doesn't work with the Solstice bellhousing. So, I need to know which flywheel/clutch/TOB combo I should use. Apparently the Solstice/Sky 2.0 and 2.4 used different TOB's so I assume the clutches and/or flywheels may also be different.

    Who would be a good Kappa pro to contact? Thanks!

    Or on second thought, maybe I should go with a Saab flywheel and clutch. I'm sure the crank balancer and flywheel are meant to be used as a pair. All this mixing and matching is a pain in the ass!

    It would help to know what year the LK9 came from, then I might be able to help you out (for right now I am assuming about 2004 era 9-3). The clutches are different part numbers, so I am not sure what to tell you exactly. I say the Saab clutch and TOB if it works in the bellhousing (and since you should have that already from the motor).

    If you've got an LK9 and a solstice trans, you'll need an LNF solstice slave cylinder and and LNF solstice flywheel clutxh kit for the best match.

    Why can't you use the solstice lnf master cylinder under the floor? Just make your bottom hinged pedals actuate the solstice part. Should be a matter of fabbing a bracket to hold it and matching the solstice pedal ratio for proper throw.

    Apparently it's an 07-08 (got it locally off ebay - just checked the auction info). I really don't know much about Saab cars and the research I've done seems to indicate that the 9-3 bounced back and forth between a 5 and 6 speed trans depending on year.

    I would go with what Maven said. I think the LK9 and LNF are close enough relatives that the clutches will interchange, but I could be way off base. Maven would know that stuff.

    Yeah that seems to be the most logical way to go. Are Ecotec cranks neutral balance? Can I switch and swap flywheels and crank pulleys/balancers? Or am I getting myself into trouble? I guess the real question is if I go with a LNF flywheel and clutch, should I also use a LNF balancer or the Saab balancer?

    I could use the stock m/c but there are two main things I don't like: a) it's plastic b) it'll require a remote reservoir. I'm early in the design stage so anything can happen.

    What about using a tilton MC? not sure how the stroke and stuff is compared to stock, but it looks nice. Or, look into Chase Bays. He makes parts for Hondas that look stellar.

    As for the neutral balance... I am not sure, to be honest. Something I have never had my hands on to do. If you are going to have the motor apart, I recommend having it balanced out to 12k rpm as a unit. But thats just my anal nature.

    Nah, the motor is staying together. That's why I'm trying to figure this out ahead of time.

    Should be fine, we put aftermarket clutches and flywheels on all the time. As long as the flywheel is balanced to spec I'd imagine no issues would arise.

    Can I ask what its going in?

    Yes ECOs are internally balanced. You can mix and match flywheels and crank pulleys to your hearts content. I'd stick with the stock pulley since you've got it, but clutch should def be solstice parts.

    I think finding an integrated reservoir clutch master will be difficult. Even an aftermarket cylinder (which will likely be way over $60) is most likely gonna be remote. Nothing says you need the reservoir in engine compartment though
