Everything to change on rb25det gearbox?

[silviaz]

Hi all, I keep finding more and more things to change when doing a clutch change but my mechanic didn't tell me there were other things that could be changed so wanted to check if I got my list right (let me know if anything is missing):

Full clutch kit that comes with all the components

rear main seal (might as well while its out)

clutch fork

input shaft oil seal

Fly wheel remachined

front and rear input shaft bearing (worth changing?)

Have a think about an upgraded clutch pivot ball, it's cheap insurance.

Also look at the clutch fork. Mine suffered a lot of wear in 10 years.

The rb25det pull type gearbox doesnt have that from what i read.

Yeah no pivot ball for the pull type. I went through the same process last year:

 

In the end I just ended up getting the spigot bush and clutch fork. The fork not really being needed as it's solid but thought what the heck and did it anyway. Flywheel came with the clutch. There's also the little rubber dust cover that goes on outside. Which in the end also came with the clutch.

I hope you are getting a good clutch. It makes all the difference for actually enjoying to drive the car

I can't see spigot bush on your list, it is worth always changing that when you do the clutch

Yeah will be a basic exedy heavy duty clutch. Do you know if its worth replacing the input and output shaft bearing? I'm guessing they are behind the input shaft itself before the 4 bolts?

That will come in the clutch kit, that's actually the main thing + clutch, I need to change because I'm getting grinding noise at idle and when accelerating at certain speeds but goes away when the clutch is in.

Do you know if input and out shaft bearing is behind the input shaft or it's deep in the gearbox? Wasn't able to find info on it.

They are both in the gearbox.....box out if they need replacing

Upgrade anything you need to remove, that could help performance.

 

 

Like the exhaust. While you're there, may as well do the turbo since it touches the exhaust too...

Get the tailshaft double checked too...

I know the gearbox needs to be removed, but was wondering if it's right behind the input shaft as the amount in labour will be alot cheaper to replace it, but will be alot more if it's buried all the way in the gearbox.
