Post subject:  Crankshaft pulley question - KA24 vs L18
Having read about the KA24 head - on - L20B block conversion, I have a bit of a strange question.

Seems the bottom ends of these two motors are somewhat similar. Does anyone know if the crankshaft pulleys would be interchangeable as far as fitting onto the crankshaft ? Its probably a long shot, but may save me some time / money / all of the above.

Reason I ask is that I want a crankshaft pulley for an L18 that will take a ribbed belt to drive a supercharger, rather than the normal v-belt. With a bit of luck, KA24 might be suitable.

Secondly, if anyone has a KA24 crankshaft pulley, what is the diameter of the pulley where the belt runs ?

Dave,

I don't know for sure, but from what I've seen it looks like the KA24 is smaller on the nose of the crank. I think this is to allow the smaller timing sprocket to have some meat in it.

As I say, I'm not certain about it. If you find out, let us know. :wink:

Best of luck.

Thanks.

I thought it was a long shot getting it

a) to actually fit and
b) to be the right diameter to drive the supercharger at the right speed.

I might still try to track one down. I guess if its smaller, I could get it machined to the right size. Better than being too big.

Don't know if this is going to be of any use to you at all but my old SC14/L28 setup used what I was told was a VT power steering pump bolted onto the front of the crank. I'm not 100% on what a ribbed belt is but this was like this VVVV.

Diameter was around 170mm IIRC. Enough to spin the SC14 to 5psi anyway.

That's pretty much what a ribbed belt looks like.

Might have to have a look under the bonnet of the family VX commodore. Mmmmm, wonder if the wife would notice if power steering suddenly stopped working ? :D

I thought that the SC14 used a v-belt ? Unless I'm getting confused with other types of supercharger - I pretty much looked at them all over the last month or two :? . Perhaps they came with both.

Anyway, if some (or all) SC14's came with ribbed-belts, I might give Datsport a ring to see if they would have a suitable pulley lying around.
