broke a mcleoud twin disc.... so I have a mcleoud twin disc in my camaro with about 5k miles the car is cam only (415hp) and today I changed out my fluid like I regularly do and took it out for a spin, I cracked 2nd gear pretty hard and the car free revved weird so I got it back to the shop I work at and tore it apart and found one of my clutch disc had stripped splines, has anyone had anyone else had this problem? a friend had it happen twice with the same clutch...

Shorter spline engagement is going to lead to that. It goes back years, BTW. http://www.noid.org/~lj/StreetTwin/McLeod.htm

1Sic...
the splinne part of the input shaft goes through the disc(s) up to pilot bearing. Given the 2 discs my guess is each disc has a thiner spline than a single disc to allow 2 discs and a floater plate to live in the same area as a LT1 single disc clutch.
What I would suspect is the spline (26) componet itself may have come from China as most clutch companies get their parts there and assemble them or in some cases get the entire clutch from china and re-brand it.
I doubt Mcleod gets entire clutches from China but possible their splines. Just a guess.
I found a local clutch company in SoCal and went to see WTF they did and saw how they make the splines in-house. Their comments on China being the source of many clutch company componets is what I am sharing as a possible link to the failure.
I am on my 4th LT1 single disc clutch and will go twin if/when this one fails as I see the twin disc design the only way to deal with higher than stock HP/TQ. Mcleod would be the twin I would go with unless the company I got mine from ever decides to enter into that market which I doubt they will.

We have no problem standing behind our product when there is a Mfg related failure. Send it in and we'll take care of it.

Apologies for any comments related to McLeod fabrication or material sources that are false.
"Just a guess" comment should have referred to Clutch companies that were directly noted in a conversation with the local shop. McLeod was not one of them.

I understand. I'm not jumping your case. I just want to set the record straight incase anybody else has concerns of the origin of our product.

the problem with the mcleod splines is that they don't fit the t56 input splines with tight tolerances. over time the looseness wears the mcleod clutch hubs and the input shaft splines and develops play. when there is enough play present, the splines eventually strip. ask me how i know..

and when your mfg related failure takes out the input shaft? what happens then?

1) Misalign bellhousing,
2) Soft Hub material,
3) Soft Input Shaft material,
4) Hub position on Input Shaft,
5) Major and Minor dimensions of Hub,
6) Contact dimensions of Splines.
When you send in your stipped out hubs also send in this destroyed input shaft and we'll rockwell it.

Hey Billy, I need to send it my disks and the splines on my are eaten down. Are you saying that this is a know issue and you will cover it? I called up and just told the rep I needed a rebuild and he said $75 for each disk, now that I see this, I am wondering if you guys will show love for mine and cover the issue too

There are a couple things that can cause spline wear,
1) Misalign bellhousing,
2) Soft Hub material,
3) Soft Input Shaft material,
4) Hub position on Input Shaft,
5) Major and Minor dimensions of Hub,
6) Contact dimensions of Splines.
