Dual Feeding with CK's new separator plate

[Blazer406]

I'm a little confused. I am about to assemble my tranny and try this dual feeding. I have a CK billet forward drum. I have the new CK Separator plate. I read on posts here that the instructions (in CK's book) for how you dual feed has been revised since the manual was printed..... just wondering what steps I am missing.

1.) Leave out 2nd (middle) sealing ring on the center support.
2.) Install new separator plate.

I am unclear if I have to plug any kind of hole now since the separator plate has these blocked.... the hole where the bolt is for the center support?

Oh,..... Chris... those solid teflon rings you sent with the billet drum were a Mother Hubbard to install.... any reason you don't want a scarf cut ring on there like the pic in the manual?

You have to stretch out the rings,then re size them. I use a hose clamp (the sides not the center with the grooves). The rings with the scarf cuts allow more of the circuit to leak,that is bad and the reason for the one peice ring.

I took a junk direct drum and beveled the lip out of the center and made it more of a cone. Smoothed it out on the lathe with some paper, use it everytime to fit the C/S rings.......Takes 2 seconds to fit em...

Credit to Bruce on that one.

Thanks guys...

We did get the solid rings on there. One was a real pain.... I used my center support once I got them small enough to get it to slide on there.... it has stayed on there for the past two days.... maybe that will squish it down for good.

One interesting note.... my local tranny builder friend said he thought the scarf cut ones sealed better... because the high pressure forced them out making a more positive seal. Looks like that is not the concensus here huh....

From my experience

I've had on, 2 occasions, the scarf cut rings (on the forward drum shaft) get sheared off on final assembly. Once assembled you can't see them. Also the solid rings are a larger width than the scarf cut. Don't know about sealing ability.
