had my first tow in yesterday :frown: (thanks Scott).... with a mystery starting, flywheel/ bendix issue. When I took the cover off today... I saw that the teeth on the RAD were spinning around the stationary flywheel so they had apparently come loose. Has anyone experienced this before? Is this problematic with the RAD by chance? Is the outer teeth wheel component machined or welded onto the flywheel? I have yet to pull her so I can't exactly tell for now. Prolly gonna do a lightened 62T Flywheel I already luckily have with Group K or LPW.

That sucs, I planned on going RAD on the blaster (have an advent on the SJ).
Guess it is stricktly lightened for me.

I am not sure if you can fix it
if you cant i will buy it off you
i want to pull one part and check out the magnets in it

Yea, I figured it was done with, just curious more than anything if the outer tooth ring was machined or welded somehow onto the the big metal purple POS....

normally the ring gear is a press fit, as in you heat the ring gear, and chill the center hub, and then press them together.
at normal temps they fit so tightly there is no spinning.

Hey reed.
Teeth + flyweel are seperate.

Major downfall to these flywheels. Toby had on do simular thing.

Who's the best in quality of work and price for lightening a stock flywheel .
Sorry for the threadjack but at least it's flywheel talk :biggthumpup:

search for a thread on lightened stock FW there are a few.

Join the club...I posted this same question...over yonder a while back. (A week before Daytona) Nobody had a clue. It's goofy... It happened to 2 of mine. They both started slipping during the cold weather. Below 50 degrees. I had them re-pinned @ 3 spots. Good luck.:banghead:
Its probally a material shrinkage issue. The Cold Water...it does things.

Werd... really not a big signiificant diff in temp here- slight if anything. WaveDemon told me of another guy we ride with about a similar experience with RAD. Nice flywheel and all, just don't know if it's justifiably worth the $ though... So you're saying not to ******** can it and have it repinned heh? I'll have to check that out.
Butti, if you're asking if it has the pretty purple cover that you can make adjustments to w/o taking it off- no sir.
Olls- I figured that one out- I prolly didn't phrase it right or made it sound confusing.
thx all for the feedback...

Like I said I have one that is exactly the same as yours, I think it is due to the flywheel being aluminum and the ring gear being something else or hardened?
On stock steel flywheels in cars, you have a heated press fit ring gear and they are both steel so when they expand they do it at the same rate. a steel ring on an aluminum hub is probably not a good idea especially when the aluminum expands more and faster than steel, which I am not a metalurgist but I think I read somewhere that it does.
Pinning it will probably work so long as the pins are able to withstand the vibarations but for the peace of mind I would just use it as an ashtray.
Mine is part of "The Wall Of Pain" in the shop.

Ring gears usually "fall off" the Rad flywheels when they have been overheated or been subjected to extreme heat. (Cooling line failure, etc).The Aluminum gets compressed as it expands at a different rate than the steel ring gear, then the approx .002"-.003" "press fit" is reduced and increases the chance of it spinning off later. I suppose it's possible that the colder weather could increase the chances of a failure, as the aluminum does expand a different rate.

I would guess incorect press fit of ring gear.The press fit has to be quite large for the application .002-.003 won,t cut it.
I have a rad flywheel for sale if anyone is interested
