I ordered all new bolts from Mazda to attach this lightweight (Racing Beat 9.5lb) flywheel I picked up for my swap... however the bolts dont go into anything on the flywheel or clutch... am I missing some nuts or something?

I bought most everything used for my swap...

ACT S/S clutch

Racing Beat 9.5lbs flywheel
+ new friction disc

Also, on the ACT clutch, the side of the clutch disc with the two yellow dots in the center... does this face the flywheel or the pressure plate?

Thanks,

You need the counterweight that is a stock part on auto-tranny cars. The lightweight flywheel bolts to the counterweight. See pics here: http://maxcooper.com/rx7/parts_info/flywheel/index.htm

I'm converting from an automatic so I already have the counterwieght....

I'm not talking about that... I'm talking about how the clutch attaches to the flywheel... vai the 6 outer bolts and 3 outer alignment pegs....

I hate a racing beat flywheel because of this. ANd I hate it even worse when people bring me used racing beat flywheels and want me to make them work...of course there is NO hardware with them.

The RB flywheel has no threads tapped in, I suppose because it's aluminum they thought it would be a bad idea. Just use longer bolts and nuts on the backside. Some (maybe all?) of the RB flywheels dont have the 3 dowelpins to line the PP up with. In my mind, this opens the door for the PP being off center a little introducing vibration. Perhaps yours has the dowelpins.

ITs even worse for the nonturbo flywheels they sell. Not only are there no dowelpins and no holes tapped, but the nonturbo clutch set/stock flywheel has the friction surface sunk down about 1/2" on the flywheel, and there are raised mounting pads on the stock flywheel that the PP bolts to. RB thought better of designing these raised pads onto their NA flywheels, so they just send rinky dink little round spacers instead. Yep, 6 little aluminum 1/2" round spacers is all that holds the entire clutch on, with those models. And of course, when people show up with this used stuff, none of the bolts or spacers are there. Last time I wound up using a stack of flatwashers to substitute for these spacers on an NA flywheel.

Bottom line, go with srmotorsports or act flywheels, IMO.

 

holyshiat!! Glad i never recomended the RB flywheels. That is a bunch of horse **** IMO. They should be shot if all that is fact. insane half-*** job.

I have always used ACT or the SRmotorsports FW. Great quality and they come with all the bolts needed.

As far as the yellow dots go. The side with the protruding input shaft splines on it goes towards the flywheel. If i recall, that is the side with the dots.

 

Thanks for the replies guys,

Yea the flywheel was used and didnt have any hardware... so should I just use the Mazda bolts + crush washers and get some grade 8 nuts to hold em on? I guess I was lucky because my flywheel had the dowel pins -- damn and I thought Racing Beat made only good stuff.

Okay, that is how I had the clutch disc laid out but I wasnt sure if that was correct so I wanted to be safe. Are the clutch discs replaceable or do I have to buy an entire S/S kit from ACT when this one is roasted? I'm hoping with the fact that I dont ride the clutch nor do dumping that I'll be good for a bit.

All you need are some bolts, lock washers and nuts. That's what the flywheel (new) comes with. It's a bit more of a pain than the SR or other flywheels but it's not a huge deal.

You can purchase the clutch discs seperately (at least from ACT's Site ). Most normal stores typically only carry the combined kits (clutch/pressure plate).

 

Just any grade 8 or higher bolts and nuts with lockwashers will work. Just be sure you dont have any clearance issues with the bolts on the backside of the flywheel, interfering with the engine.

A clutch disc only goes on one way. It won't fit the other way. There is a flat face side, and a side with a protruding face. Since there is not enough room for the fat face to go down towards the eshaft, it must point up, and sit in the open space that the PP provides.


Most of the time if you buy some sort of autozone stock-type replacement kit, or even a mazda kit, the disc and PP are diakin. IF you note on your act, the disc is also a diakin, the same one so far as I can tell. Any stock-type organic disc for 87-95 turbo fits, to my knowledge. Sometimes you can find autoparts stores that sell just a clutch disc itself for like 75 bucks, and it'll be the same thing as what comes in the kit, a diakin disc.

But no, I dont think they do clutch rebuilding anymore.

This is true. the ACT discs are just stock discs.( unless a puck style of course) The only upgrade is to the PP and flywheel if you go that far.

Kinda a waste of money and false advertising. As they say it is a "upgraded disc" Ahhh secrets of the trade
