Torques

This is an older post of mine but I just thought I should update it and explain what the problem was. Long story short the friction plates were below their service limit. New they are around 4mm, and service limit is (according to OSG) 3.5mm In addition the crank seal gasket wasn't sealing 100% anymore and that led to an oily clutch. Not sure what came first and why the clutch was worn after just 10,000km .. but all good now. OSG refresh kit via Nengun

Antenna got bent in the car wash ..

Not really, but I just like stuff on my car to work ...

Thanks, I was in the car wash and forgot about the antenna ... 😅 It got bent so I was looking into a replacement. However I got lucky and could make it work again.

I'm looking into replacing the antenna mast on my R33S2. Nothing to be found on EBay ... Is there a replacement from another Nissan that would fit?

Hello, Thanks for the input. I also saw the 4075-1S listed as R33GTST bearing https://koyo.jtekt.co.jp/en/products/detail/?pno=RCT4075-1S Here's the 40SA3 https://koyo.jtekt.co.jp/en/products/detail/?pno=RCT40SA3 Major difference seems to be 'd' which is 74.5mm vs 82.2mm Too bad I don't have an old bearing / carrier to check.

@BK Thanks for the input, it's not a lot of $$$ and my only concern was that the throw at the release bearing end would be different compared to the OEM setup. I think they used the shortened pivot ball to get the travel right. This is for an R33GTST .. and after 25 years a refresh wouldn't hurt.

Cheers, The clutch isn't overly heavy (OSG TWIN) but looking at the machined pivot engagement point I thought it might be a more precise setup for the clutch...

I'm about to change my clutch and came across this upgraded clutch fork kit: https://conceptzperformance.com/czp-upgraded-heavy-duty-clutch-fork-kit-nissan-skyline-89-92-gt-r-95-98-gts-t-r33-30531-cd000-build_p_14924.php Would that be something to consider while the clutch is out or waste of $$? Thanks

Hi, Yes, thanks for the input. I'm more than happy to buy from NSK or NTN or SKF. It would help if I had the OEM dimensions but according to SKF I might have found something using 30502-69F10 https://vehicleaftermarket.skf.com/mt/en/products/VKC3737

Hi, The situation is that I need the standard OEM release bearing for the standard clutch ...

I'm trying to order the release bearing, the part number seems to be 30502-69F10 (?) Nengun says it is no longer available. https://www.nengun.com/oem/nissan/30502-69f10 1997 GTSTS2 Is there a replacement part # ? Cheers

Cheers ... I usually ordered through Nengun or RHD but Greenline is substantially cheaper on an OSG clutch service kit I need. I popped them an EMail for a quote.

Hello, Has anyone experience ordering from https://greenline.jp ? They're offering quite competitive prices but I've never ordered from them .. Cheers

Thanks for the feedback .. My car makes about 320kw at the engine .. and at the moment I have a OSG Twin installed. Now after 13,000km it started slipping in 4th/5th. I think the stop and go traffic killed it since the plates are worn. In an EMail OSG said the clutch is more geared towards harsh engagement and would wear used 'normal' The OSG refresh kit would cost me around GBP 450 plus (taxes, postages etc) The Nismo Single GBP 710, the Nismo Twin GBP 1,140 (all plus) That's why I was thinking just getting the single to get a bit more life out of the clutch. I also never liked the rattle of the OSG twin. On the other hand just buying the refresh kit would be the cheapest option.

Thanks, was that the single or twin?

Has anyone experience as to how much power the Nismo Single can actually hold? Thanks https://www.nengun.com/nismo/super-coppermix-clutch

Ahh .. OK .. it's a permanent sound, not dependent on gear selection. Sometimes it's almost gone (wishful thinking) Earlier I found brass shavings in the oil. (actually the oil was slightly laced with brass particles) I refilled with the OEM Oil which seemed to work fine. The 3rd->4th reluctance / crunch is annoying. Especially under higher revs. A gearbox refresh might be expensive and time consuming, that's why I thought of just biting the bullet and getting a brand new R34 unit. I think the 'conversion' to push is quite simple ... there are even markings in the cast for the R33 slave I heard.

Hello, As per title. I'm driving an S2 GTST and the gearbox makes a slight whining noise in all gears - so possibly one of the shaft bearings(?) Shifting is actually ok, except for 3rd to 4th which doesn't like swift changes. I'm considering buying a brand new R34GTT gearbox and convert it from pull to push and sell of my old box. My question: Are the R34GTT boxes improved compared to the R33 ones?

Ok, thanks ... I'll open a separate thread on my question.

Just wondering, what is a 'big box' ? Cheers

Yes, thanks ... I bought from both of them and always compare .. RHD is also 'helpful' with the customs declaration.

I'm going to order from Japan anyhow so I've got access to the whole lot. https://www.nengun.com/drivetrain-clutch-kits/#m:1;c:76;g:1

Yes, thanks! Couldn't agree more .. not all manufacturers give a torque rating though. I asked OSG about the rated torque and they wrote back that they don't give that figure (only power) How's the pedal feel on the NISMO Twin?

Well, I'm at around 450ish hp at the crank. That's 335KW, so the clutch should ideally hold 550+ (410KW) My main grief with the STR is that that plates are worn just after 13,000km. I suppose that driving 70% of the mileage in traffic killed it .. Here's OSG's response If your vehicle's power is under the clutch max capacity, then it is often caused by driving too gently on the clutch. Our clutches were mostly designed for aggressive use in mind, and it is better to be used somewhat rough on occasions.
