I'm putting an SM465 into my Toy. I'd like to go hydraulic clutch. Can anyone tell me any OEM aplications that used an SM465 with a hydr. clutch or how much throw I need so I can start measuring slave cylinders off another truck?

Thanks

Is your bracket homemade, and if so do you have any pics (io not what's it off of)? <IMG SRC="smilies/biggrin.gif" border="0">

the 1-1 1/8" is right...find out the bore size and the throw into your master cyl. before you go shopping, once you know the fluid displacement your master puts out, you can do a little math to figure out the bore of the slave cyl you need to get 1-1 1/8" throw you want.

Is this going into a cruiser or a pickup?

I put a 465 in my cruiser a several years ago and had to use an old, straight, cast clutch fork that had two holes to choose from on the slave cylinder end of it.

I used the inner hole (closer to the bellhousing) and it has worked fine with my cruiser clutch MC and slave.

I originally tried to use the stock stamped steel fork (came with the sm465) and I didn't have enough throw to disengage the clutch completely.

Oh yah, a friend of mine has an '85 chev 4x4 that has a factory hydraulic clutch on his sm465. The MC and slave cylinders are really expensive though (more than my cruiser ones!...it is pretty rare that I find a chevy part that costs more than a cruiser part)

This might help ya a little.. I used the stock hyd slave and master off of a 81 CJ-5 with a GM 151 and SR-4 tranny on my SM465. I made a little bracket to hold the slave and all was good. www.4wd.com has the parts you need if you can't find anything used that will work..

HTH..

Here is a way one of my IRC buds worked it out on a 420. should work on a 465 also.


The part number on that is Wilwood 340-1470

I used a 1975 Toyota landcruiser slave on my NP435, and it worked out really well. It's small, cheap, and easy to mount. The wilwood stuff in nice, but expensive. Any parts store around should have the LC slave.

I know it's not cheby, but this might help.

Bump from the dead.

I'm nerding this up with some math.
V = 3.14 x R² x H
3/4" bore master cylinder, 1.25" throw, creates 0.5519 cubic inches of fluid movement.
My 13/16ths slave cylinder, worked backwards from 0.5519 cubic inches is a .09388" throw.
Right?
You guys are saying 1.125" of throw.

How big of a problem is that 0.18", should I find a different MC?
