unfortunetly not. I'm stuck here. I don't think I'm going to be able to get these guys to buy me a new flywheel.

 

 

back on topic now. anyone know what size of spacer to use? or am i fawked?

 

I do!

First you need to measure the height distance from the upper rim where the pressure plate bolts to, compared with the clutch friction surface area. Then calculate the spacer difference required. Not difficult.

Since RB flywheels are compatible with both 225 and 215 pressure plates, they require six aluminum spacers and longer bolts for 225mm pressure plates. No spacers required and OEM bolts for 215mm. The aluminum spacers are about .315" tall (give or take a tiny amount due to differences in manufacture ie these two from my kit are .312 and .320 in the same kit!).

So Adrian, this is what I'd do. First measure all six of your RB aluminum spacers and use the average. Then get a careful measurement of the difference between the two levels of your flywheel. Then add the thickness of the RB spacers to the flywheel measurement and see how close it comes to .640". It will come up just shy (probably around .130" or more). Find the right thickness washers to get you to .640". That's it.

You could use simple steel washers as spacers. You may have to go through 50 to 100 washers at the hardware store to find the best ones, but it'll work out in the end. You may have to stack two or three if they're too thin.

 

sorry to see the machine shop hosed the flywheel. that's why i just wipe it down with an emery cloth meself.

 

So I called RB and they said I have an old flywheel. It worked with 215 and 225 clutches and pressure plates, but it won't work with the new 225mm pressure plates they sell. I need to pay to ship my 225 stuff back and they'll ship me out 215mm clutch and pp for free, so I'm going to be out $100 or so in shipping, but i'll get a new clutch. That, or I could order their new 225mm flywheel and the clutch and PP I already have will work. What a bunch of ****, huh! Anyone want to buy a RB Steel lightweight flywheel? It'll work with 71-92 12A's or 13B's, but you have to use a 215mm clutch and PP. $200 picked up!! $250 shipped.

 

So i called RB, Ordered an alluminum flywheel TH. It got here today. The *** hat told me I didn't need the hardware kit since I already has the bolts and counter weight. well they didn';t send me the clutch hardware. Has anyone stacked washers to use as spacers. And you people wonder why i ******* hate racing beat. I called them back today and they said too bad I need to order their hardware kit. another $41 plus shipping. **** RACING BEAT THOSE CANIVEING BASTARDS!!!

 

Stacking washers will work better than it sounds. So long as you have a lock washer on every bolt and torque them down you shouldnt have a problem. Just make sure all the washers you use are the same size, and you use the same amount on every bolt to make sure it sits level.

 

Well fawk it. I got some grade 8 5/16-18 bolts, 5/16-18 nylock nuts, and SAE grade 9 washers. 4 stacked are .333 high so I'm going to try them out. If they break and my legs get chopped off I'll let you all know, if I survive.

 

Please post pics if this occurs! I want to see some carnage!











Not really... Hopefully it'll work out for you for now.

 

Sorry to hear about your problems with RB. But on the plus side, the flywheel and clutcth sit far enough forward in the car that when it goes it takes out the parts at the firewall, like the fuel lines. So your legs and feet are safe, sort of.

 

I guess my next mod is a fire system. lol. kinda... Well I got it all back to gether and driving. no shakes rattles or rolls. clutch is really grabby. I can't wait to break this thing in so I can go nuts with it.
