Help! Do I have A wrong flywheel?
I put my larger 1983 flywheel on my 82 motor so I could use my aftermarket clutch. While looking at rotor weights on the mazdatrix website I see that the 82 and 83 had different weights. Is this going to cause a problem when I start this thing up? Do I need to put the smaller 82 flywheel clutch assy on the motor? HELP!

This is listed in their explanation section at:
http://www.mazdatrix.com/f-writng.htm NOTE: Excluding the TURBO, all the different flywheels and clutches, from 74 through 92, are basically divided by 215mm clutch (74-82), and 225mm (83-92), then by rear counterweight needed for the engine. We mix and match these all the time. This means if you want to put the larger diameter clutch assembly on a pre-83 application, just let us know - it is no problem. You just need to remember what diameter you have when you next purchase clutch parts. Greg O. |
To clarify...
The problem isn't with flywheel weight, the problem is with flywheel imbalance. What Mazdatrix meant about mixing and matching is if you want to put a 225mm clutch on an early engine, they will give you the correct automatic counterweight (which a lightweight flywheel bolts to) and the larger-diameter lightweight flywheel. Looking at the counterweight chart, '79-82 use a different counterweight from '83-85. So no, you can't put an '83 flywheel on an '82 engine. I prefer the 215mm clutch myself, it has less rotating mass on the trans input shaft = easier/faster shifting and longer synchro life. I noticed a difference when I went to a 225mm clutch on the same transmission. Unfortunately I had no choice for the same reason as your problem... can't put an '80 flywheel on an '84 engine. Also the '81-82 flywheels are the lightest of the bunch! |
