Clutch replacement .... And what else to replace?

[PeterW]

I'm getting the parts together for a clutch replacement. Doesn't need doing quite yet, but I want to be ready. For a 1996 (model year 1995), so far I have on my list:

Clutch replacement kit 22000-PR7-305
Release bearing 22810-PR8-003

Is there anything else which makes sense to do at the same time?

I found a confusing thread on NSXprime which talked about the "main oil seal" 91214-PL2-003 (98x80x10) (NOK). What is that? Is it the gearbox main shaft oil seal? Make sense to replace that at the same time?

Thanks for any advice.

Hi Peter I replaced my clutch in February this year and was recommended by Kaz to replace the following to ensure a factory silky smooth origanol pedal feel and I have to say it certainly felt fantastic once fitted.

Both driveshaft diff oil seals.
Clutch release bearing fork.
Release bearing guide turret.
Speacial grease which is not readily available to buy in the UK (if you would like the small amount to do the job, pm me and I can post some out to you foc)

The reason for the new clutch fork and guide turret is because the small scratches and abrasions over time can cause the clutch pedal to feel rough if not replaced.

Have a look here where we also discussed about the clutch in detail: http://www.nsxcb.co.uk/showthread.php?14344-My-gearbox-revision-thread

'main oil seal' is the big seal on the engine side behind the flywheel. It's a must. Depending on miles and heavy clutch use you may also consider the release bearing guide and its fork.

You might also go with 2.7 l of MTF and two new seals in the gearbox at the axles.

Good advice thanks Pride and goldnsx. And sorry I didn't find your gearbox revision thread when I searched before!

Your release bearing guide looks 10x worse than my was. I can imagine that your clutch pedal is now much more smooth. It looks to me that the humidity in the UK contributes a lot more to the wear of such areas. Is that rust/corrosion on the blank metal?

you should be able to navigate to the relevant diagrams and parts numbers from here.

not sure about the grease, but if you search Kaz’s blogs you may get your answer before someone else finds it for you

Check out my build threads last few pages. It's from when I replaced the clutch assy on my car.

Parts # as above advices.

For the grease in UK, you can get the Honda Super High Temp Urea grease #08798-9002.

It was on years of back order but got back in stock although with bit extra price tag.

I think it’s about £25 for just 50g tiny pot – size of small egg.
If the same chemical, green-ish colour.
Honda one is safe on metal-on-metal as well as metal-on-plastic application.

I prefer the molybdenum fortified dark grey UM264 but very expensive and unless you regularly work on the specific area, never going to finish it as it’s in large tube.

Hi, I am going to order the parts but they appear on different pages in the parts catalogue . Can someone please check that I have the the correct part numbers for the diff seals ( 91206-pr8-005 and 91207-pr8-005 ) and the main oil seal ( 91214-pl2-003 ) for my 1991 NSX.
