is there a bigger clutch slave cylinder?
 

I installed a new exedy 6 puck clutch with new pressure place , new throw out bearing and new pilot bearing. It feels when I am letting go of the clutch pedal it jerks a little, if I rev up the engine it doesn't jerk. Do they make a bigger clutch cylinder?

Maybe those are qualities of the new clutch? I have the stage one exedy clutch and it doesn't do that. But as far as I know there isn't a bigger one.

I have read other posts on like subarus that its normal because the hydraulic jitters... Because the clutch is so hard . I hoped that this was also the same for ours. My pedal is pretty hard, if I let go of the clutch fast it won't jitter. I hope I don't hAve a defective clutch... Thanks man!

OK, Just some HISTORY for you on Mazda Clutch Hydraulics..

Your Mazda Clutch Slave Cylinder Bore/Inside and Parts dates back to 1985 (yes nearly 30 years) first used in FC RX-7, also used in MX-5, B, E, T Series Trucks with 4.6 litre 4 cylinder Diesel Engines. (FB01-49-460 Slave Kit).

Your Clutch Master Cylinder Bore/Inside And Parts also dates back to the same models as Slave Cylinder since 1985 (B312-41-52Z Clutch MC Kit).

So to answer your original question about an 'upgrade' to your Hydraulics because of your new Clutch Plate and Pressure Plate, etc, I would say definitely NO.

When you have a Mazda large truck which uses a much larger Clutch Plate 'system' than any Rotary, and carries many tons in weight, I call any 'upgrade' as not needed and unnecessary.

Just make sure what you already have is in good working order/specification.

MUHAHAHA!

YOU all NooooooooBBBBS ! :lol:

There is one vendor and only 1 that sells a bigger Clutch Slave Release ... and that's Japan's Fujita-Engineering

I have it years ago, took it out about a year something 2 ago cuz I thought it failed, but it end up being the Clutch Master that failed. Haven't reinstall it yet.

I think they use the stock piece and "enlarge" it and use some custom pistons in it. it does help to make Clutch engagement smoother.

you bought a(n unnecessary) racing clutch, now you will have to live with your bad decision

SoooOOO U SssaaAYAINNNNGGG a 6 PuCCCK CluTCH will N0t make mY CaR FASteR ?!?!?!?!?!?!?!

yes it does suck... I thought I was gonna get like 60 more horse power too. :\ oh well....
Thanks guys, I checked out that Japan Engineering website. Thanks man I'm gonna order it and try it out.

alright guys the reason that I was getting a lot of jittering, or chatter is because my flywheel was warped. I had a spare flywheel had it cut and the jittering went away. Very awesome...lesson here is get your flywheel cut with a new clutch.

Any good spanner jockey would have resurfaced the flywheel when replacing a clutch, its mechanics 101.

There were several lessons. Best wishes on eventually learning them all :wavey:

Thank you! I have learned a lot from all of you guys.

I am not a mechanic, I do this for fun on my spare time. I have rebuilt a few rotary engines and have done all my installs. This place is a great resource, the members are awesome at responding to my questions. As I learn I share my mistakes so if anyone reads my threads they will hopefully not make the same mistakes I did.

:Peace::Peace:
