Shaft material
« on: December 12, 2009, 01:19:22 PM »
Anyone have a clue what alloy the input shaft is on a VW 091 transaxle? Anyone have ability to analyze?

I should have said reharden and temper. This is uncharted territory for me for sure. I'm feverishly gathering all I can on the subject.

Maybe you should be looking at the center material of a clutch disc instead? Since its what normally rides on the shaft??

Just thinking outloud.

Two wrong metals can eat each other up but you KNOW the clutch center material is made to ride on it for a LONG time.

Ya got the wrong idea my man. I agree but I am not using a clutch disc. TRhe input shaft will be driven by  one of the 2 Ramsey RPV chain sprockets which is 1117 4140 or 8620. depending on final selection.

I have followed your progress on this machine enough to KNOW you are not using the actual clutch disc.

But the sprocket inside your custom casing WILL be riding where the clutch disc did.

Thats why I suggested trying to look a the clutchs center material. Its hardness should be duplicated as close as possible IMO.

You get too tough a metal and the tinyest play and it might chew the splines off the tranny input shaft. Just my thoughts on it.

They also sometimes treat metals in applications like this to be a sort of self lubricating cause in its normal enviroment they cannot have oil flinging around to get out on the clutch disc.

But in your app there will be lube there I believe? Correct?? I am quite sure of this being the chains there.

But even with lube I have seen splines fail. So I suggested looking at the clutches material is all. Might be worth the trouble in the long run.

AZ transaxle might be able to tell you the shaft specs and materials.

In not Spendeola's site likely states it as they like to tout how much better thiers is made. I seem to foggily recall they have talked about it and might openly tell you what it is right on thier site and how much better they claim thiers is. To them its a selling point.

I follow ya and don't disagree. Most ,if not all,clutch discs I have seen were obviously softer than the input shaft for just that reason. The clutch hub splines will fail long before and I have personally only seen 1 disc with the splines worn. But it's a moot point as you pointed out. My stuff rides in tranny fluid.  I appreciate the input at all times!
