Anyone have a significant amount of slant 6 miles and shifts on a Hyd. throwout bearing in concert with a diaphram clutch with a 833od trans & 76 bellhousing? What/whose bearing and clutch did you use successfully?

not with the hydraulic throw out bearing but with the diaphragm clutch.
I'm using the larger of the two pressure plates that were used in the 2000 ford explorers with clutch disk and throw out bearing from a 10" Borg and beck three finger setup.
the most important part of the throw-out bearing on your hydraulic is that its face needs to match the pressure plate. if the pressure plate is designed for a flat face throw out it will not last with one that is radiused and vice versa

search inexpensive effective clutch in the forums for details on my build.

Thanks for lead.

If Explorer used a hydraulic throwout bearing with the stock explorer diaphram clutch....would that be viable combo.....ie match on throwout bearing surface to PP?

I purchased both the Ranger/Explorer 9 1/8 PP/Disk and 10 PP. Both have retaining bolt holes around 8.6 mm or just about .340" dia.

Sites list a Ford 10mm (.392") x 1 x 23mm bolt ATP ZX102 for the Ranger/Exporer/etc application but it's unlikely that will drop in a 8.6mm bolt hole in the PP. The Ford PP Bolts for 85 & earlier small block V8 were 5/16-18 and came in a set of 6 in ARP 150-2201 fastener kit.

Maybe the PPs were made with too small a bolt hole (6 total)?
or.....Maybe the sites have it all wrong on the Ford bolt size?
or maybe my measurements are off?

So the question is did you run into this diameter difference and substitute 5/16 bolts and threads? The .3125 bolts would be slightly loose in the PP hole in that case?

Obviously I'm trying to get the correct drilling/tap size for the flywheel determined. Seen a 9 1/8 drilling pattern? I'm measuring 6 equally spaced holes on a 10 1/4" diameter with 5 1/8 straight line distance between adjacent holes.

I've found the stock Ranger/Explorer 9 1/8 disk appears to fit the slant flywheel. Since I just had a B&B disk come apart (rivets pulled out, hub halves separated, springs let loose, and hub cracked thru rivet hole and broke into two pieces......I'm not anxious to use another B&B disk.

I'm going with the Ram 78125HD hydraulic throwout bearing which is flat faced and has a great diameter match to the ford 9 1/8 PP fingers.
The 833 od input bearing retainer collar must be built up from 1.25" to 1.37" to use that unit but Ram good reviews seem to exceed reviews of the McLeod more expensive throwout when it comes to leak potential.
The Ram also uses a guide pin off the retainer which feels more secure than the loosely installed 1400 series McLeod unit.
