Request help identifying a custom billet slave

[brnin8r]

Hi all,

 

This is a great forum, I read here all the time.

 

Still tearing down my SBC 240Z. Previous owner said it had a Muncie M22 Rock Crusher. The clutch slave is a billet piece, threaded body, with a push style when pedal is depressed (versus pull). The bracket was a one off (some welded steel L bracket), mounted to the block/tranny area with the billet body on the engine side, with the pushrod facing rearward, pushing the clutch arm. I noted it appears to leak some, so I'm wondering:

- get a rebuild kit (not sure what it is though)

- replace it with the same item (since bracket is already fashioned)

- go with something new and better, but easy bolt-on (suggestions?)

 

I was thinking it *might* be a Coleman, but I can't find an exact match in their catalogs, or any identifying markings on the piece. It is probably 10 -15 years old (car has been a SBC for a long time). Here's a pic, any help is appreciated!!

Thanks! That looks like the one; Coleman's website was hard to navigate.

 

I also found a Coleman mounting bracket, 375-301, and the only picture I could find is here:

I was thinking of getting the Coleman made mounting bracket, but looking at it, I'm not sure it bolts to the bellhousing between my SBC & Muncie. Also, the Coleman unit puts the slave mounting plane parallel with the plane between the motor and bellhousing.... but I noticed my setup brings that mounting plane back several inches (see pic), since it seems the clutch arm used for my Muncie is pretty far forward.

 

So to buy a bracket, and new slave, looks like I'm over $100. While spending $ for new parts, is there a better bolt in setup for my SBC/Muncie combo?

 

Appreciate the feedback.

I wouldnt worry about a new mounting bracket, if the one you where using works, might open up a can of worms to get it to work right. only thing else i could think of is a SS M/S to S/C line, to tighten the pedal up.

Does your bellhousing have the bolts as shown in this picture ? If so you can use a stock Datsun 1974 B210 4-speed slave. Fits nice and does a fine job. Scarab 155

Scarab 155: I'll have to check and see, but I don't think so (I think it is a lakewood bellhousing, and I don't recall any additional mounts).

 

hoov100: Thanks for the feedback. The reason I considered the Coleman manufactured bracket was from the pictures it looks like the pushrod might be at an angle with this one-off bracket, and I wasn't sure if that contributed to the slave cylinder leaking (with some sideways force as it goes in and out, wearing it out)? Since I have everything apart now, I wanted to put it back with the best external slave option.

 

While searching around, I came across this interesting hydraulic conversion for Jeeps (but should work for anything). Seems pricey though:

It's a possibility, but how many years has it been in there?

[brnin8r]

10+ years.
