    Re: Clutch Questions...Help!

    Here are the measurements. PM me your email for the pics if you want them... I suppose I could post them up here as well.... not that anyone else would enjoy seeing them

    Slave Cylinder

    Width of Base 4 7/8

    Height decompressed 4 5/16

    Height of Diphram shoulder 3 3/4

    bleeder screw base to masterline 2 7/8


    Flywheel


    outer starter teeth side to side 14 1/4

    outer edge to outer edge (no teeth) 13 9/16

    thickness at thickest point (edge) 1 7/16

    thickness lip between clutch plate surface area 1 1/16

    flywheel clutch surface area width 2 1/2

    flywheel height to clutch surface 1"


    clutch plate


    total width 11"

    clutch plate surface area width 2 5/16

    Center spindle height 1 3/4

    flat measurement of clutch plate thickness 3/4 - 1 1/4


    Assembled

    flywheel clearance on the side till clutch 3/16

    total height from flywheel mount to top 3 13/16

    total height to the top of the fingers 3 7/8



    Of course I couldn't find my digital unit... so measuring to the 16th will have to suffice for now. If it's gotta me within the 100ths of millimeters let me know and I'll try to look for it again.

    This should give you a general ballpark if your LS7 Hendrix setup will be the same or not.

    Some of us want to see what you went through. I changed out my flywheel on jack stands but I don't see this happening again PITA. I may need a new clutch soon and if so I would like to hear how this install went and if the LS7 slave worked for you.
    You didn't take pics when you changed your flywheel!? lol
    I'll take plenty of pics man.

    Got a couple questions for ya:

    1) Did the flywheel move when you torqued un the bolts (loosening/tightening) or does the crank hold it still?

    2) Did you reuse the same flywheel bolts? (I've heard some people replace them, but I plan on reusing them)

    3) Did you drain the trans when you pulled it?

    I used a tool that grabs the teeth of the flywheel, I will take a pic of it and send it to you if you want. Not sure that you need the tool but I used it since I had it. B TW, that stock flywheel weighs more than 50 lbs so make sure you're not undermneath it when you slide it off of the crank.

    I only had 6,000 miles on the car so I reused everything except of course the flywheel. Just make sure you use a torque wrench when you go to tighten them. I have just north of 22K miles on the V with no problems.

    I did just to lighten it up a bit. Plus I was plannig on changing the fluid anyways. Word of warning - DO NOT USE that royal purple crap in your T56. I tried it and it shifted like, well, crap.

    Once you get the new flywheel in you will wonder why you waited so long to do this. If I ever bought another V I might even do this over the shifter!

    The more pics the better....post em, or IM me please!

    +1 on the torque wrench!

    I guess I'll get a tool then for the flywheel.

    I've never used and will never use RP....thanks for the heads up. Mobil 1 ATF in my trans and it shifts like butter!

    I'm looking forward to relearning how to do drive it with the boat anchor dual mass fw outta there!

    Re: Clutch Questions...Help!

    Don't use Royal Purple for engine oil either... I paid mucho dinero for it... and it burned about 2 quarts of oil between changes ( truck motor FTW! ) but notice I have never had any problems with Amsoil or Mobil 1... (only ran amsoil once, every other time ran mobil 1) So I'm sold on Mobile 1 for engine oil... I couldn't believe how much RP that thing burned... back to Mobil 1... stopped entirely... unreal.

    Maybe it coated stuff SO well that it went right past my piston rings and got burned up!!!! HAHAHAHHA

    Great pics, Rob! Timely, too. I'm having my UUC FW installed as I speak.

    Gotta say, your car looks pretty doggone clean underneath.

    Re: Clutch Questions...Help!

    Doesn't everyone here jack up there car and clean the underside when they wash it? Just kidding, only had 6K miles on the car and I don't drive it in the rain so the bottom of the car stays clean.

    No but I should have. When I did the swap I didn't know about them but next time it will get one.

    Re: Clutch Questions...Help!

    I live in CA so there are a lot of sun days and I drive the truck on the wet days. The V has seen a couple of rain days (one of them was on Infineon raceway!) but not many. While I am doing an oil change I usually wipe down the bottom side of the car.

    You are correct, everything is stock except for the flywheel.

    Get a beater. Mine (my V) only very, very rarely sees even a hint of rain, and that's in Michigan, no less.

    Re: Clutch Questions...Help!

    Ya I agree....get a beater and drive that when it's crappy out. It will make you appreciate your V that much more when you get back into it.

    Randy, have your mechanic take some pics!
