Push type clutch vs Pull type clutch

I was just look into the clutch for my GTR and I think I have a push type clutch. My was a 1990 R32 GTR.

The question is, what is the difference? I know people who have change their push type clutch to pull type clutch?

What is the difference between the 2 type of clutch? Advantage/Disadvantage?

Is one heavier than the other?

I too am curious about this same issue

I have an 1995 R33 GTS-T, also, if I have a push type clutch can the car be converted to accept a push type clutch and vice versa? And what would be the pros and cons of doing so?

Late,
Daniel

Don't expect an answer on this. I can't seem to find the info and the people in the know don't seem to want to answer the question. Perhaps with more and more people buying cheaper parts from Japan, the more secrets and myths there are where people dont know what to buy, the better it is for the specialist as more poeple will feel inclined to pay the premium.

As I understand it, the early R32's are push and the later R32's (1992ish onwards) and 33's / 34's are pull type. The pull type is a slightly larger unit but I don't know what the actual impact is on performace. I would expect an early push type twin plate would be significantly stronger than a late pull type single plate.

You can convert from push to pull (early to late) not sure about the other way round.

Not sure how to tell the difference - someone mentioned cooling fins and the direction they run in giving the answer as to what you have - someone else mentioned the position and direction of the actuator telling you what you have.

I have never been given a definitive answer.

Does anyone know???

cheers
martin

To spot if you've got push or pull then look at the gearbox bell house casing where the clutch fork pokes out. If the cylinder is infront it's push, behind it's pull. (unless you have aftermarket conversion, which mounts extra pivots within the bell housing.

I don't know the reason why nissan choose to change. But lots of aftermarket clutches are push due to it being easier to make a strong diaphragm spring and release bearing arrangment within the available room. Especially with multiplate clutches.

Some 32's can be modified to push by re-drilling 2 lugs cast in the bell house to re-mount the cylinder in the opposite direction. 33/34 pull to push conversions require extre pivots to be mounted within the bell housing.

I knew that was coming. Did think it strange though how this question never actually seems to get answered - until now that is!

Cheers cord

one other thing - if its behind (ie pull) then is the cylinder between the fork and your back box or the fork and your headlights? (if that makes sense)

fork and backbox.

I was told last week that using a pull type clutch allows a stronger diaphram for clapming pressure, but using a push type you can have a larger clutch pack due to the shorter release bearing (ie. quad plate being push).

The difference between a push type and pull type pressure plate is the way the clutch is disengaged. On the push type, the diaphragm is pushed by the release bearing when you press the clutch pedal. On a pull type, the release bearing pulls on the diaphragm to release the clutch. Push type systems are easier to assemble since the release bearing doesn’t have to be attached to the diaphragm, while pull type systems are more efficient because there is less flex due to the shorter “A” distance as shown in the diagram. On a pull type system the cover has load in only one direction for engagement or release, where the push type is loaded in opposite directions which means more deflection (flex).

I have a spare R32 GT-R clutch assembly sitting in a box in my shelf. How can I check whether it's push or pull? Looking to sell it but first I need to know what I'm selling

Are there any common faults with the retaining mechanism on the pull type clutches coming adrift?.

In my mind a push type clutch seems more reliable but just an opinion.

Seen a few post on other platforms where the pull type locking collar has come adrift, especially after agressive clutch pedal dumps?.
