215mm vs 225mm????????
 
Does anyone know how to tell if you have the 215 or 225 flywheel?? Im not sure what I have but I know what I had bought to replace it. I only want to do the clutch job 1 time a yr or 2.

Please give your feedback. I have a 82 with 4 port engine of dont know what yr..

Thanks!

82 should be the 215mm flywheel, they went to 225 in 83

BUT, there is a possibility that they still have the original 215 flywheel. You have to drop the tranny.

Just measure it. The 215mm is 8.465"(roughly 8 1/2") and the 225mm is 8.858", just under 9"

Is that diamater or radious?

My guess is radious but that is just a guess

radious

So its the radius from the pilot bearing to the outter end?? Thanks for the input. Going out to measure now.....

Radius= 1/2 Diameter right?

R Lee 07-10-03 10:12 AM

Trannys out....Aluminum flywheel and it had these small spacers between the pressure plate and flywheel..Dont know what they are for.

Yes r=1/2d

Yes radius = 1/2 diameter

Randy,

The differance between the two is that the 225 flywheel is flat and the 215 is recessed. And these measurements are the diameter not the radius.

Dont loose those spacers. Without it, the pressure plate will sit too far away from the t/o bearing and will cause the tranny not to disengage. if thats the 215mm, racing beat no longer make the replacement friction plates. 225 is still available.
