It could be maybe an error on the flywheel surface or teeth flywheels are kind of like brake rotors you should always replace them instead of having them redone that’s one thing I have learned as a mechanic Over the years. So the place that done it could of left anything from a little piece of metal to a nick in it or anything. I’ve never seen one do that unless something was wrong it shouldn’t be because it’s not broke in usually when it’s not broke in it’s usually just hard to press down until it breaks in

 

What clutch did you replace it with? Did you change the pressure plate?

 

Yes everything was replaced as I got a clutch kit. I put an excedy xrs clutch on my S.

 

those clutches are a bit stiffer and will behave like this at least when new. rev up a bit more for this clutch 1.5 aint very high,, were all use to our baby soft stock 1zz clutches lol

 

Shouldn't chatter. We had flywheels resurfaced and never had a problem but it was before cheap flywheels became available, more than 20 years ago and I only went to one machine shop which is now closed. As far as wearing in there is very little difference and it it chatters it probably will not stop, but nothing to loose. The real issue is what to do to make sure it's fixed the second time. Could be parts or the resurfacing, but which one?

One of the reasons why I'm glad I am retired. Guess wrong and it comes apart 3 times?

 

Update: Chatter is definitely going away as I put more miles on the clutch. I can now engage at 1k rpm with minimal chatter whereas before it was quite significant.
