Just got a flywheel in the mail that i bought for my 5 speed '87 n/a rx-7, the problem is...it doesn't look like my old one on the back of it. My old one was consistent in shape on the back with no protruding or obvious "counterweight". The one i just got in the mail
has an obvious counterweight on the back along one part of the edge. It's not aftermarket but, i'm thinking it's for a s5 or an automatic s4. anyone have pics of a flywheel from either of those years (as long as you're sure). bottom line, it's not the same as my flywheel that i just removed.

 

Automatic flywheels have a counterweight integrated. Sounds like you got sent an auto flywheel.

 

Here's a picture of an identical flywheel to the one i just got in the mail. A '86-'88 n/a 5 speed shouldn't have that counterweight, right ?

 

Correct. That is an auto flywheel.

 

Hmm, it may be right though, a little birdy just told me that it's correct...a birdy that re-builds lots of rotarys.

 

I have never seen a manual flywheel, but I know they they have build in counterweights, so that looks like it is most likely a stock manual flywheel.
I can tell you 100% that it is NOT an auto "flywheel". First of all, they have a flex plate, not a flywheel. Second, it is much different looking from that. Third, autos DO NOT have a built in flywheel. It is bolted on and a separate piece. This is why you always have to use an auto counterweight with aftermarket flywheels - because it it built in to the stock manual flywheel.

 

Yatzee ! You're right. I was in such a rush when changing my clutch the other night that i didn't even notice that my old flywheel had that counterweight on it. Here i am pacing back and forth cursing, when the whole time i had the right part. Alright kids, our lesson for today is "Don't open your mouth until you're sure you know what the **** you're talking about". Lesson learned. Thanks for the help guys, appreciated.

 

I got owned. I don't even know what I was thinking.

 

It happens to the best of us. I was screwing up all morning at work, I'm glad I'm somewhat back to normal.

 

Yea it's sad because I know better. Just goes to show how long it's been since I've had an engine apart. I miss it.

 

Hha, oh well . I'm the rotary newb so..um, yea that'll be my excuse. haha

 

so how do you explain your stock flywheel? you said it had no counterweight...

 

It's integrated. The counterweight for aftermarket flywheels comes from an auto.

 

so he had an aftermarket already?

 

that looks fine
everyones smoking the reefer - i should be too, but no money
bolt it up and go

 

Well, I corrected myself in a post and said that "I was in such a rush to get **** done that I didn't even notice that the old flywheel had that integrated counterweight." Thats all, in the confusion of rushing I didn't notice that protruding piece that is the counterweight on the old one. Next time, no rushing the job...

 

sorry... totally missed that.

 

in case anyone was wondering, smoking pot before a clutch install doesn't help really....lol
