JB_BA Posted September 27, 2003 Share Posted September 27, 2003 Haha. Well...one thing leads to another. In the process of adjusting my shift linkage, the welds that held the slave cylinder to the bell housing broke...both of them...at the same time. It was cast iron I believe...so that explains that bit... now my question is...have any of you ever mounted one to the frame before? I'm thinking I'm going to drill bolt holes in the frame rails, slid the bolts through, and mount it to that, as it's a little messy down on the bell housing where the old welds were. If anyone has a better suggestion please let me know. I'm going to tackle this one tomorrow afternoon. JB Quote Link to comment Share on other sites More sharing options...
dmyntti Posted September 27, 2003 Share Posted September 27, 2003 I am not sure that is a good idea. Remember the engine and transmission move around a bit. I think the clutch engagement would be sloppy and you would have a problem keeping the slave engaged to the clutch fork. It would be better to make a bracket to mount it with the bellhousing bolts. Maybe someone else can chime in with better directions of what would work as I have never done this. Quote Link to comment Share on other sites More sharing options...
Guest 350zgto Posted September 27, 2003 Share Posted September 27, 2003 The slave cannot be mounted to the frame. The engine/trans will torque over and generally move around, this would cause your pushrod to fall out as the engine/trans moves away from the "frame". Cast iron, this sounds like a Chevy? I have made a slave bracket from steel plate to mount a slave cyl. It bolts through the bellhousing bolts and places the slave in the correct position. This bracket will work with any Chevy bellhousing/trans combo. Chevy pickup truck, 1962 has a cast iron bellhousing with a slave boss cast in. Is that what you have? If you do not want to fabricate something, then get the pick up bellhousing or a Lakewood scattershield, the Lakewood has a slave boss in it. Be aware the Lakewood flanges where it bolts together will eat up your ground clearance, so if your car is a JTR conversion and has lowered suspension the bottom flange of the Lakewood will be very close to the ground. I had a 66 Malibu with a rat motor with a Lakewood. The bellhousing banged the ground going over speed bumps, etc. Or switch to new style hydraulic t/o bearing.

Guest 350zgto Posted September 27, 2003 Share Posted September 27, 2003 Just curious you mention welds for slave mounts and cast iron. Did you weld mounts onto a cast iron bellhousing? If so, that is why they fell off. Welding cast iron requires a special technique and unless the weld is exactly right, you will not be able to trust it for strength. You are better off making a bracket that bolts to the bellhousing or getting a bellhousing with the boss cast in. Quote Link to comment Share on other sites More sharing options...
JB_BA Posted September 27, 2003 Author Share Posted September 27, 2003 I know the engine is going to torque some, but I'm talking about mounting it to the main frame rail, and there I think there is enough play in the rod to allow for the torque. If you guys don't think that's a good idea, what about fabricating a plate or "box" that will mount on the bellhousing bolts, then mounting the slave to that? Any other suggestions. Keep in mind I'm short on cash, so while purchasing a used scatter shield with the slave cast in is an option, I don't know if I have the money for that. By the way, the BOLTS that were welded into the bell housing were cast iron. I don't think that they was strong enough to hold up to constant torquing. Not to mention it didn't appear to be a very good welding job. Anyway, I'm going to get something done this afternoon, I've got a few other little issues I can deal with if I haven't decided anything about the slave cyl... Later guys, JB Quote Link to comment Share on other sites More sharing options...
JB_BA Posted September 27, 2003 Author Share Posted September 27, 2003 Did you weld mounts onto a cast iron bellhousing? Not me man, whoever did this job the first time. Since I got this thing I've been correcting mistakes. Hopefully I won't make one by bolting this cylinder to the frame. Sounds like fabricating a mount is the best way to go.

peej410 Posted October 4, 2003 Share Posted October 4, 2003 when i setup my clutch slave i used a wilwood pull type, i bought a heavy duty gm clutch fork out of jegs (lakewood product) cut the end with the push pivot for the slave off, drilled a 1/4in hole in the fork put a bolt through it with some washers spaced the heim joint that comes with the slave in the center, i bought another heim for the other end. using a piece of flat stock that i put a slight twist in, i was able to position the slave so that it pulls at the correct angle by mounting it to the bolts of the transmisson mount itself. the clutch pedal is very stiff but is very linear and very smooth. there are lots of options im sure that my suggestion isnt ideal. however i love making stuff over and over again just to try and squeeze out that extra little bit of efficiency/performance...... goodluck -pete Quote Link to comment Share on other sites More sharing options...
