Midget Thrust bearing conversion

In another forum, I have been watching a curious Midget project - the guy is swapping the engine but keeping the transmission (which is the opposite of what I would do) More to the point he has installed a contemporary thrust bearing. Thought it might be worth sharing here.

thrust bearing is this:

Is that a hydraulic throw out bearing?
when I did the 5-speed conversion on my TR6 I got rid of the clutch slave cylinder and installed a hydraulic throw out bearing. I like it!

do you have pics? Also, how did you determine which bearing to use? and, how do you bleed one of these puppies?

thanks!

I will look for pics. Bleeding was super easy. As I remember, I let one hose hang down and pumped the clutch until the fluid flowed steady and then reattached the hose end. The hydraulic clutch I used came with the HVDA 5-speed kit that I bought. Here's the installation instruction sheet....

I found a pic.... hope this helps.

JP, I researched this conversion and I really liked the idea until my son and I bought a 1993 Jeep Wrangler which comes stock with one. While asking advice on the Jeep forums it became clear that just about everyone had or wanted to change to an external slave cylinder set up because of access when it starts to leak. A lot of these folks are hard core off road people and they have getting home as a priority and a bad/leaking slave really makes that difficult to do considering the terrain. That said, for those of us willing to pull the engine/transmission to fix a leaky TOB it’s a consideration and it removes a lot of potential slop from our clutch system. I’m still on the fence on this one.

Rut, no doubt that when/if I have a problem with my hydraulic throw out bearing the trans has to come out and I’m ok with that. Mine has been in for approximately 12-13 years.
A broken fork pin would also necessitate pulling the trans as well...

Elliot, where does the second line go in your picture?

JP here's a photo looking up from the bottom of the car. One line goes to clutch master, and the other line (bleeder line) terminates in a mounting bracket attached to a mounting bolt on the bell housing.

Thanks for this! I wondered if that is what it was. I am tempted (one day) to plumb a similar line at the high point of the 1500 clutch line (higher than the MC)
