Has anyone used a hydraulic throwout bearing to avoid the use of a slave cylinder?

I have a Tilton Racing hydraulic bearing. It's been installed for over 9 years and more than 25k miles. Never a problem. I'm also using a Tilton floor mounted pedal set.

I had problems with mine. I've set it up twice and still have had it extend too much and loose fluid. I thought i had it the last time, it worked great with no leaks but i decided to take my car down to the frame and restore it so when i pulled the trans out i found that it was leaking. I think i will go to a slave cylinder because if you do have trouble with the hydraulic bearing you have to pull the trans to change it or to even change the spacer washers. I had looked at a stop for the pedal but then you would have to figure out when the clutch is fully disengaged and it's not like you can see in the bellhousing very good. Hope this helps.

Use the forum search feature with a couple of keywords like HTO and slave cylinder included. There is more info in there than you can absorb on this topic. Plenty to help in your decision.

Default Here's all you need to know...

There has been tons of stuff written on this subject. The bottom line is this:

* About 4 out of 5 Cobra owners have problems with their HTOB.

* It is incredibly sensitive to get set up properly.

* It provides absolutely no benefit over an external fork/slave setup.

* You should only use it if you absolutely positively have no room for a fork/slave. (ERA still does it on the FIA; Kirkham will not do it period, I believe.)

* When you replace your HTOB with an external fork/slave make sure you mount your slave to the frame so that it causes mysterious shifting problems from the engine/trans torquing over (that way we can all feel smart when we point how how dumb that was).

There, now you know everything there is to know about HTOBs.

Default It's all in the setup

I used the tilton with a t/l & found it VERY easy to install & setup.
JUST read & follow the directions. It is absolutely necessary to have a pedal stop.
Once you have everything assembled according to specs, just jack up the rear of the car ( set on stands of course ) with it in gear have some one try to spin the wheels while you depress the clutch. Have the stop set very high to begin & slowly add clearance with each depression of the clutch untill the volunteer wheel spinner can rotate the wheels without too much drag.
You will be good to go.

JMHO.

It's easy to set up. I had no problems and Tilton helped me through it. But it's not for the mechanically declined.

If you can install a clutch with a regular fork and throw out bearing, by all means do.

Some of the downsides:

1. Price. A clutch fork and throw out bearing would be about $100. A hydraulic throw out bearing is at least $300.
2. If it leaks, it will leak all over your clutch disc and ruin it.
3. If it leaks, plan on pulling the transmission....which can be a pain in the butt with some Cobras.

The only upside I know of is that they're good if you have limited space.

I would heavily advise against it though.

Any devices that fail as frequently as HTOBs do not reflect on the skills of the installers. They reflects on the skills of the designers and manufacturers. Some installers are just luckier than others.

The history of failure was mainly the McLeod HTOB's due to a defect. (read the threads) A large portion of the remainder were due to the installer; improper spacing or no pedal stop set correctly.

I don't know why so many people have problems when I've had none for over 9 years. I suspect is just scares some as the install has to be precise; like valve lash and other close tolerances. But with a good quality HTOB and a good install it should last a very, very long time.

Roscoe,
Either you are a far better mechanic than everyone who has had problems with their HTOB or there is something suspect in the design and manufacturing of some of them. You have your opinion on which it is and I have mine. .... One of us will have to be mature enough to agree to disagree and let the other have the last word. I suspect we'll soon see which of us that is.

Didn't Jamo have a "horror story" of sorts with his HTOB. I vaguely remember him scolding one of the Kirkham brothers for having put it in there. I could be wrong on that, and if so, surely someone will put me in my place.

Wasn't trying to start trouble. I just like reading different ways of achieving a task. I have my way but very open to the way others have tested the waters. I have plenty of room for a slave, ~KISS~.

I do not believe I have ever read a complaint about the Tilton HTOB. Only about other manufacturers with defects. If there was, it probably related to inproper install. But I have read a multitude of problems with slaves & mechanical setups, again usually related to imoroper setup & lack of maintainance.
I have 16000mi. on mine, it is silky smooth & no appreciable wear on the clutch yet.

Either setup can be made to work well if setup properly, there is no right or wrong, just personal preference & space limitations.

JMHO

Craig
