Master Cylinder Clutch Rod

[MY66AH]

Hello everyone. I need to know what the appropriate setting for the clutch push rod on the master cylinder on my 66 Sprite. Pictures would be greatly appreciated or measurement from the jam nut to the end of the threads closest to the mc. Thanks for the help.

With the dual MC just set it up with a little play that you can feel between the end of the rod inside the MC and the at rest pedal position.

Thanks Kurt.

Ok that worked well. Now I need detailed pictures of how the clutch line is routed. Thanks again.

I'm laid up with gout right now and not moving if i can avoid it. There were two routing s of the clutch line if memory serves. One over the top of the battery and the other in front of the heater box. I believe yours should be routed in front of the heater box but will leave it up to others to offer more.

I would offer that the problem with bleeding these clutches is the routing of the line. It is a b*tch to get the air out of the high part and the line should optimally run downhill from the cylinder to the slave. Even the short vertical loop from the cylinder means that unless you back-bleed, you have to push the air bubble all the way down the pipe. Stock be ****ed, I say.

The real issues with bleeding these are these:

There isn't a residual pressure (check) valve in these, so building pressure, especially in an empty system is difficult. As such, the bleeder needs to be closed after each pump, otherwise you are just moving air/fluid back and forth without progress. The other option is to have a check valve (speed bleeder) at the slave cylinder. I swapped out a master cylinder this week (not bench bled), but there was a a check valve style bleeder on the slave. The biggest problem I had was finding a hose that would fit this particular bleeder. After that, it only took a few minutes to complete the job and get a nice firm pedal.

The other issue that causes problems is that many of the new slave cylinders are shipped with the bleeder in the wrong port, and many people assume this is correct. The bleeder must always be in the uppermost port or you'll never extract all the air.

The other thing I like to do is install a remote bleeder. The location of the original, is just plain stupid.
