Clutch System In A Manual

[AlexCim]

Ok, well as everyone would know, i am going for the manual conversion.

I have decided to go with the r33 GTR gearbox, as Stagezilla, as its supposed to be the correct length to not require a new driveshaft

Sooo, one thing i am doing differently to Stagezilla is that i am going for just a GTST master. At the same time as buying the master, i bought a GTST slave, GTST pedal set (clutch/brake/accel).

Now, i know that the r33 gtst is a PUSH style clutch system, but someone explain to me what i am talking about below.

First, here a picture of a R33 GTR slave on yahoo JP.

And the clutch setup with mock attachment to master

Now, here is what i am experiancing. With this clutch/master (which is pretty generic inc same as GTR) when the clutch is pressed, pressure is built up in the master, therefore causing pressure in the line, and eventually makes the piston at the slave PUSH out. Now, considering i dont know the main difference between PUSH/PULL, the only way that i can see that it could "pull"(as a gtr should/need to go for gearbox) the clutch would be

a) for the little rod to be welded to the piston inside, and then the fluid from the lines to enter the "forward" chamber to "push" the piston back, causing it to pull the clutch

B) the pivot point on the clutch to be BELOW where the master attaches to the clutch, therefore making the master "pull" the pressure into it, casuing the welded little rod to be pulled back. Now, i reckon there would be a lot of strain if it was actually pulling...

soooo... option c is that it just mounts on the other side of the clutch, meaning all i would need is new lines between the master and the slave, which i wanted to get from Maltech anyway....

Sooo, anyone got any ideas...

PS, if you cant tell, im new to this PUSH/PULL thing

At the moment, the only thing holding me going ahead is waiting on my gearbox to arrive, powerFC and also sorting out this push/pull thing, otherwise, ill be finished within 1-2 months.

Give Mercury Motorsports a ring, they should be able to help you out as they did most of the work on my stagea manual convert before I purchased it. Ask for Trent on 1300 558 650.

But the box that went into mine was out of a r32 gtr, so it's prolly all different, but they still should be able to help you out.

[AlexCim]

R32 GTR is a PUSH type box (the early) or the late model 93+ R32 boxes are PULL type, the same as R33...

Im just wondering if anyone actually knows, i will be going to speak to my mechanic tomorrow anyway, but i am really eager

I think there is a pic of mine somewhere hang on a sec................

EDIT: piccy

nah its easy from a slave cylinder point of view the only difference between push and pull is the side of the clutch fork that at pushes on....ie in one it faces forward and the other it points backwards

[AlexCim]

Can i get get new holes drilled on the box to suit my slave??

BTW Ska, your car has a early model R32 GTR PUSH type box, as you have the exact same slave as what i am trying to use...

[Ska]

Cool thanks for that info

[Duncan]

Well we fitted a 33 GTR box and had to reverse the slave cylinder to fit it properly.

But the 33 GTR box actually had the points to mount the slave cylinder backwards already cast into the housing, all we had to do was tap holes for the bolts.

If you have a pic of the housing I can point it out for you

[AlexCim]

i will, just wanted to be sure that i can mount the slave that i have. This is because on Nengun, they differentiate between the PULL and PUSH slaves, so i thought there could be something different.

After i posted, i thought about it a bit more, and i should be sweet

One step closer

Ill be getting an ATESSA controller soon too

Sounds good Alex...keep us posted, I'd like to do this in the near future B)
