clutches for the B18 1.7

hello,

sorry, havent learnt the engine codes yet.

Just wondering if the clutch for a NA 1.7 is the same as the B172 340 1.7.

The 480 has higher output due to fuel injection but anyone know if the clutches are the same? I know the turbos has uprated clutch which I guess is a stronger pressure plate.

I might answer myself and have a route in VADIS but anyone know already?

cheers!

Shimon

Sorry, but they are not the same.

The 340/360 has a clutch with 20 splines (teeth)

The 440/460/480 has a clutch with 26 splines (teeth)

The clutch plates for 480es come in three sizes, depending on the engine.
1.7efi is the smallest, with the turbo and 2 litre models each being larger.
There are well priced (about 30 quid - $NZ90) clutch plates available that are asbestos free etc. After market release bearings are also readily available. I couldn't see why the genuine Volvo ones were three times the price. I have just replaced one using one of the methods in the Haynes manual - would be keen to hear from anyone else who has done this, as I think there are a few time saving steps that could be taken.

Oh, there are reasons. Torque handling capability being the most notable.

What clutch do u recomend for the early 200mm flywheel chris?

Was thinking about the black diamond one @ Â£115 i think, or is it possible to have my flywheel machined so the 215mm clutch fits, i know its been talked about loads, but i only want to do it once!!

I could sell you a 215mm flywheel if you need one. ^^

Sounds like a good idea john, but is the reluctor ring the same on the early and late flywheels?

Well, do you mean the blocks used by the flywheel position sensor?

Its my understanding that its very nearly identical. I think chris1roll swapped flywheels without any difficulty. YOu could search his posts or ask him.

Yes mate, that is what i mean, i thought they were different, how much do you want for it anyway?

I had a black diamond one... It wasn't strong enough.

If johns offering you a bigger one, go for that i would say.. the orange ECU will work with the larger flywheel, but after a while my car started boost cutting at full throttle, so I changed to a red one, its been fine since, so you may need to find a RED ECU to go with it... The blue one will not work with your crank position sensor. If you want to fit a blue ECU as they are easier (ha!) to come by, you would need a later wiring loom and crank sensor. (different number of wires)

TBH I didn't really investigate the ECU/cutout problem much, my patience was very tried by then, I had a red ECU hanging about so bunged that in and its been fine, so......

Twenty five quid maybe? Only because i'd have to face it up on a lathe...its been used with a 210mm clutch.

Your choice anyway....i'm sure theres plenty of choice in the 200mm market.

Don't worry about flywheel john, have found a 'group N' 200mm clutch from K-Tec racing, claiming 250bhp, apparantly they use them in clio valver turbo's running 240 horse all day long, so should be fine for me, or anyone else on here for that matter, think it was Â£120+ VAT. if anyone interested.

cheers tho john

Np man, glad you got it sorted.

........Not sorted yet, now got the hassle of fitting it! Supose buying it is the easy bit.

my new clutch is slipping. I have a 480 turbo, the clutch and pressure plate is for an ES. (and oh i am running 12psi of boost)

which clutch should i get

Rapid-R5 · Post by **Rapid-R5** » Tue Jun 12, 2007 10:01 pm

............The right one for that engine for a start!

Agreed - buying a clutch is the easy part. Do get and fit a new release bearing at the same time. I'd even go as far as recommending that owners of older 1.7es cars get the longer clutch release lever and bracket and fit that on re-assembly.
I used the 'engine stays in the car' method from the Haynes Book of Lies because I had sturdy roof racks I could use as a beam hoist (I'll email photos to anyone interested) and I didn't want to drain the tranny fluid.
It took a day and a half without any special tools. If I had to do it again, I think I could do it in around 5 hours....A rear drive car is soooo much easier....
I have found the feel & action of 480 clutches to be pretty ordinary compared to the Japanese cars I've previously owned. How does that compare to other members opinions?

I'm going to find out what the Techniclutch one will be like, this summer. Its for a Renault, but hoping it'll fit, it looks like it should.
