FSV clutch disc/input shaft spline

[TED K.]

Need a 200mm. 4 puck solid hub clutch disc with an approx. 18mm. [ .70"] O.D. 24 teeth spline to mach the input [ clutch] shaft in my Hewland MK8 gear box. NO one [ not even Hewland Classic-they denied they made it ] can tell me where it came from! This was the original disc installed in 1978. I have tried ALL the suppliers and mfgr's. Could this be 3/4" nominal? Any ideas? Car is 1978 Wheeler FSV S/N 010 Thanks for your help Ted Klaus-greyeagles@msn.com

Sorry- it is NOT stock VW! Stock VW is 13/16 [.81"] - There are many 24 teeth splines from 1.3" to 13/16 but after a month of searching I have found NO .7" [18mm.] spline! Anyone else have a guess?Ted K.

Why not use old hub with new driven plate? I've done that a few times when splined hubs were backordered. Talk with clutch folks.

Ted,
Did you solve the problem? I think I have the same situation.
Thanks,

I had the same issue when I bought my Royale, years ago. Sticks in my head that it might be a disk from a VW "Thing", but we are talking 25 years ago. I finally just changed the input shaft to standard VW.

Thanks - mine is also a Royale (RP14)' What vendor did you use for the new shaft?

Lee Williams of WRD may have some info on this.

no idea where it came from it was used may have even been in a box that came with the car--also a RP-14

[rusty718]

Used would be OK.

[Charlie Schmidt]

after a bit more thought about it, it's possible I used that part from a regular VW box---worth checking

I can make these type of shafts and regularly do it. I have many hobs and hobing equipent for this purpose. I have supplied Pegasus, Taylor, Lee at WRD and others for years, 1 or two at a time. Heat treated material 4340 or 4130 I need the old shaft for dimensions and a clutch disc or hub that fits the odd spline. CMW Enterprises, Inc www.dogrings.com Wayne 760-942-9170 Calif.

I removed my input shaft this AM, and it has a number of hc23910 etched in it.

If it is air cooled almost certain to be a stock VW spline.

SACHS used to make racing discs for them.

You are correct - the stock VW spline is what I am after. The rest of my shaft is proper. Wayne @ CMW is going to build one for me.
