I recently posted a query asking advice on replacing the clutch on my Z (2 seat NA). I was worried that I could get a part that didn't fit. Someone posted:

 

'it should fit the only difference with your car is the chassis. it shorter than ours'

 

The part I ordered through Nissan based on the chassis numebr didn't fit, so I've just been back down there to pick up a different one while my Z has sat in pieces overnight at the garage. I got the part number off the old clutch cover.

 

A point to remember is that not all Z clutches fit all Zs. Just thought I'd mention it.

thats a pretty hard thing to get wrong,

how exactly does the chassis of a car effect the clutch fitting????

 

I don't know but the clutch plate on the one they supplied was about 3mm smaller and the cover, although looking the same, didn't line up with the holes on the old one.

 

Andy

 

Was it deffinatly the NA clutch and not the TT clutch ?

 

I have never looked at a NA period so not shit all about them, however i do know that aftermarket clutches are sold as serpate models, this could of course be that the NA doesn't take as much loading as the TT hence can be cheaper, there might be a difference in size / fit also tho.

 

Remmember the NA was never sold over here so nissan UK have no knowledge of its requirements best to go abroad and 3rd party next time i would say.

who posted that then??

 

;-)

 

j/k

 

 

 

Yep..clutch plate & cover are slightly smaller in size for the NA.

 

Here are some Nissan-partnumbers (if you'd still need that.)

 

NA:

clutch-plate modelnr. is 240TBL, clutch-cover: C240S

friction disc: 30100-45P01

pressure plate: 02/89-09/93: 30210-30P00 09/93+: 30210-45P01

flywheel: 02/89-07/95: 12310-30P13 07/95+: 12310-54P00

 

TT:

clutch-plate model is 250TBL, clutch-cover C250S

friction disc: 30100-45P11

pressure plate: 30210-45P05

flywheel: 07/89-07/95: 12310-30P12 07/95+: 12330-54P10

 

these parts are interchangeable between NA/TT:

throw out bearing 30502-45P00

pilot bushing 32202-B9500

rear main seal 12279-0M300

clutch fork pivot ball 30537-40P00

 

The same is the case for high-performance clutches..so NA-owners: first check !

Thanks for that Eric, where do you get all this information from? Do you work for Nissan? I wish you'd seen my original post as I've got more trouble now.

 

My Z's being kept in for another night as they've lost the pressure somewhere or other(something to do with possibly needing a new slave cylinder!?). Do you have the NA part numbers for these as well please?

 

The chap said I might not need it if all goes well tomorrow but I'd like to be prepared just incase.

 

I wonder if they'd have still had this problem if I'd got the right clutch in the first place?

 

Cheers,

 

Andy

 

Andy,

I don't work for Nissan...I'm just another Z-nut from Holland ;-)

 

Anyway..my guess is that they tried to bleed the system and since that's a bit tricky, they probably failed at doing that.

Now they think it's going to be solved by replacing one of the cylinders..

 

According to the service-manual this is the correct bleeding procedure:

here is some more information on clutch-replacement:

or http://www.zhome.com/ZCMnL/PICS/clutch/clutch.html

 

for more techie articles check the links section on my website:

300zx-twinturbo.com

or the faq/tech-section on

Also the service manual CD is a great source of information.

 

anyway, partnr for the NA slave/operating-cylinder (depends very much on the year of your NA):

02/89-09/91: 30620-30P00

09/91-03/93: 30620-30P01

03/93-09/93: 30620-30P02

09/93-01/94: 30620-48P00

01/94-11/95: 30620-48P10

 

 

Hope this helps,

Eric

 

 

oops...I think my link went a little out of control ;-)

 

 

 

If the clutches are different then does that mean that the gearboxes are different, because I changed mine last summer(because when I bought the car it was running with no oil),I had great difficulty getting it to fit. In the end I have had to put some spacers behind the starter motor to bring it away slighty.

 

Yes..the whole gearbox is slightly different also.

I'm surprised you were able to fit it !

Hopefully you wont get problems with your driveshaft and things like clutch/flywheel.

Hi Eric,

 

Thanks for the extra info, you're right they are having problems getting any pressure from the master cyclinder to bleed the clutch. They think I should get a new master cylinder and a slave cyclinder repair kit.

 

Has anyone got any tips of tricks they can try to get this sorted or should I just buy the new bits?

 

Do you have the part number for the master cylinder for a 89/90 2+0 NA please? And also a slave repair kit for the same car?

 

Cheers,

 

Andy

 

 

 

Andy, maybe these stories taken from tt.net make you think twice about the replacement of either master/slave-cylinder.

This are just two examples out of many with people having the same problem as you have.

 

>>>>

Well, just to let you know that I had the same situation (experience) right after putting a new clutch. The pedal pressure changed from hard to very soft and

the clutch started to slip badly (I mean very very bad - the new clutch is badly burned twice). Later I find out that there are two bleeder screw in order to

completely bleed the clutch system and the mechanic didn't know about it. He always through there is only one bleeder screw where is located on the

clutch slave cylinder. So I was very mad because the new clutch is badly burned and started to slipped. But anyway, the other bleeder screw is located

on top of the right hand side of the engine compartment next to the fender.

 

 

>>>>>

I had the same problem with my car my local mechainc dident know there were two places to bleed so i had three master cylinders, two slave cylinders,

and two clutches replaced before i decided to take my car to a certified nissan mechainic and have them fix my problem in 15min by just bleading the system properly. Luckly my mechanic dident charge me for all that extra work, but i was still pissed off because the car is my daily driver and it was out of commision for several weeks. Im not shure exactly where the two bleader valves are but i seem to remember one around the fluid resovror and the other on the slave or master cylinder.

 

---------------------------------------------

 

 

It's also important to pump the pedal at least 5-7 times when bleeding

 

 

anyway...about the partnumbers:

 

Go to http://www.twinturbo.net,

to the 'docs'-section and then to index 5-D-1 and move down from there (5-E-1, 5-F-1, etc.)

there are all the partnumbers for every little detail you'll need for the master and slave-cylinder

 

-Eric

 

 

Hi Eric,

 

Thanks for the part number info. I had a look at it but don't really know which part I need. Would you be able to tell me what part number I need to tell the Nissan garage to order for the master cylinder? I'm afraid I'm not very technical when it comes to this sort of thing so don't really know what I'm looking at.

 

Thanks,

 

Andy

 

Andy, I checked with courtesy Nissan for you and these are the exact/latest partnumbers, since the ones I gave before can be a little outdated...

 

Master-cylinder NA: 30610-48P54 ($51)

Master-cylinder rebuild kit : 30611-0H625 ($7)

 

Slave-cylinder NA/TT : 30620-48P60 ($34)

Slave cylinder rebuild kit : 30611-0H625 ($7)

 

-Eric

 

Hi,

 

Just had Nissan on the phone with the part number for the Master cylinder:

 

30610 30P58

 

Is this right?

 

They can't get it until next Wednesday (14th) though, gutted! Does anyone know where I could get one sooner?

 

It's getting depressing driving my girlfriend's knackered old Golf.

 

Cheers,

 

Andy

 

Just been whinging to a work mate about my clutch and he's offered to lend me his Twin Turbo while he's on holiday next week!

 

Every cloud has a silver lining!

 

I suspect that I'm not going to want to give it back when my NA is fixed though. Anyone wanna buy an NA with a slight clutch problem ;-)

 

Cheers,

 

Andy

 

Ps Thanks for all the advice Eric

 

now theres a recipe for disaster..!!!!!

 

Andy, I can't find any info on that specific partnr. Nissan gave you..but the first 7 digits of that partnumber are correct for a NA-master cylinder, so you might have a winner..

(TT-master cylinders start with 30610-40Pxx)
