Lightweight Flywheels, NOT just for Race cars anymore.

spmdr said:
The LW Flywheel is reported to be 5 KG or 11 pounds.

It's a little heavier than the 1910 or 2057.

I checked all the threaded holes, 5 /16 Fine.

They asked if I wanted Metric thread, nope.

I checked the Bolt hole and Pin hole locations.

ALL the pressure plates I have will BOLT up, S1-5.

However, S1 PP has only 2 pins, those pin holes

would need added, the Bolt pattern is the same as S2-3.

So far so good.

One thing I just noticed, the Flywheel to crankshaft

bolts have minimal head clearance.... Hmmmm.

Maybe something like this bolt: https://www.mscdirect.com/product/details/67805721
 
It's been awhile on this thread,

but sometimes things just grind

to a halt...

I little bit ago, I was prepared

to spot face all the LW flywheels

for more crank to FW bolt head

clearance.

And here is what I found:


-The bolt holes are a bit bigger than

they need to be.

-there is a chamfer on the hole.


Those together make it LOOK like

the underside of the bolt head will not

fit flat on the FW.


That is not the case, with the better

quality STD bolts I checked.

But, the curve of the FW does hinder

getting a socket square on the head

of a STD bolt, not a big deal but...


I'm more inclined to use these bolts:


or maybe the hex version... or...
