I recently bought a clutch master cylinder off eBay. Unfortunately, it isn't going to work. This doesn't look like ANYTHING like a 1984-92 cylinder. It actually looks more like the later ones to me. Does anybody know what this might fit?

thats a slave cylinder to start with. and from the pic it look like its a slave cylinder that will fit

 

Okay, you're right. Maybe I should explain exactly what I'm doing here. My car is a '61 Mercury Comet. The drive train is a 4.3 and Camaro T5. I already have a Wilwood clutch master cylinder (with remote reservoir) mounted under the drivers side fender well. I needed a slave cylinder, so I ordered this. But when it came, it looks more like a master cylinder to me. Sorry for my ignorance, but how exactly does the line and fitting connect to this thing?
Bryan

 

There is a hole on the back of it, probably a 3/8" hole. The line goes in there and then there is a small roll pin that holds it in place.

 

Ah. Okay, using a hose never even crossed my mind. I was expecting something where the line actually screws in. So I need to buy the hose assembly. Actually, it looks like I need to find a bracket and shield too. And probably an adapter for the hydraulic line coming off the master. I'm starting to think maybe I would've been better off using an aftermarket slave cylinder. Anybody want to buy a brand new 1984-92 slave cylinder for $10?

The bracket for it is built into the T5 bellhousing. For a hose, you can try to find a stock hose or you can do it the way I am. I bought these adapters that allow you to use a normal stainless braided line for the clutch line. I would not use the regular red/blue hose ends though. I would have a shop put permanent fittings on the ens. These are the fittings though.

Thanks Built91Z28. Those 3AN fittings look like THE way to go. I'm not using a Camaro bellhousing, so it looks like I'll have to fabricate a bracket. You've already been a big help. Just 2 last questions and that's it, I promise. Is this a "pull" or a "push" type slave cylinder? And do the Vortec 4.3's have the same bellhousing bolt pattern as the older non-vortec V6's? (I don't have the motor here to match it up). Thanks!
Bryan

 

Both the T5 and the 93-97 T56 use a slave cylinder that pushes. The difference on the 93-97 T56 is the way the fork attaches to the bellhousing causing it to pull on the pressure plate rather the push like traditional pressure plates. As far as I know the 4.3 uses the regular SBC bellhousing bolt pattern.

Which bellhousing are you using? From what I've been told, if your using a lakewood bellhousing made for a mechanical clutch setup, even putting a slave clyinder on it will not move the fork enough.

 

No, it not a Lakewood. I don't have that kind of money! It's just a typical small block Chevy bellhousing. It came w/ the T5 when I bought it. Probably from a truck originally.
Bryan

 

Not even sure how I'm going to attach a bracket in that exact location either. Hopefully I'll figure something out. Another reason to always do your homework before buying parts. Even if they're cheap, it adds up.
Bryan

 

Yea attaching a bracket to that probably isnt going to be easy. If your willing to sell that one I know there is a f-body one for sale right now in the for sale section for a decent price.

 

Ok, after reading I get that you're pretty much just trying to get the slave to work. IMO keep the slave, sell the bell, and get one from an 82-92 Fbody. Here is a picture of what you need:

The black thing is the heat shield with the nuts welded in place.

IF you decide to try to fab a mount, here is another side picture of the bracket for it:


If you want a pic of the hydraulics too, I can get one of those for you too

 

Thanks for the pics Vice04. It would be nice if I could use a Camaro bellhousing. The only problem is the way it mounts at an angle. Actually, I've never seen one in person. Which way does this point the tranny? Upwards or downwards? If it directs it upward, there's no way there'll be enough room in the tunnel to accommodate that transmission.
Bryan

 

It doesnt point the trans up or down. It rotates it 17 degrees counterclockwise. You can see it in the top picture above.

 

Really your slave would be slightly lower than the mid point of the transmission. My B&M shifter had a curve to compensate for this, I never had a stock one. Without a picture of the tunnel, or seeing it in person, it's hard to estimate clearances. However, if your bell that doesn't rotate the trans works, the 17 degrees wouldn't make too much of a difference is my guess

 

Oh yeah. That definitely won't work. I've spent some time looking at my transmission. As far as finding a place to mount this cylinder, I think the pull-type is probably a better option for me. Either a CNC or Howe. Thanks for taking the time to help. Again, if anyone needs a new slave cylinder for really cheap money I've got it here.
Bryan

Edit: I see Vice04 posted while I was typing the above! I bought a B&M short shifter, but it does NOT have a curve in it.

 

If it was one of the aluminum ones I'd say I'd take it, but sorry not too fond of the composite ones, had about 4 of those crack on me. NAPA won't even sell me the plastic ones anymore because I just kept bringing them back for warranty lol

 

I may have figured a way of making a bracket for that Camaro slave cylinder. One thing I'm a little concerned about is if I can't find a heat shield. How necessary are they really?
Bryan

 

How much for shipping to 02790?

 

Sorry Sawyer. Not for sale anymore. I figured out a way of mounting a bracket to my bellhousing. So I'll be using it now. I bought the cylinder from Mikebo on eBay. I'm pretty sure he has more of them. Good luck!
