Thread: Hydraulic throwout bearing

Tweet

Whats the concensus on these? I am converting over to manual trans and want to go hydraulic. It seems a hydro T/O bearing would be much simpler than a hydro slave cylinder (needs linkage and possible bellhousing). Are hydro T/O bearings reliable? Is there a brand you guys reccomend? Has anyone ran one?
thx

I have installed a lot of the McLeod hyd. throwout bearings, and have had really good luck with them, we have put them on everything from Cobra replicas to hot rods. You just have to set them up carefully so they do not over stroke and blow an o-ring, other than that they are great.

thx Jimi G. I assume they come with directions to set them up correctly? What size master do you typically use, I have been told to go with a 3/4 bore...Make sense?

I figured I would just buy the one from wilwood, not too expensive and small. Like this:

I usually use a 3/4" bore master cylinder with them. No problems. As Jim said, watch your adjustment. They work great when they are set up right and free up a lot of area that a z-bar or a slave cylinder would otherwise take....

The main drawback with those concentric cylinders is that you have to drop the trans to do anything to them. Other than that they're great.

Some of the Lakewood bellhousings have large removable viewing plates, with that bell you wouldn't have to, I am a fabricator at heart, so if I didn't have one in it, I might just make one. The only draw back is that it would kill the SFI rating.

I have had a Mcloud (sp?) TO bearing in my Superformance Cobra since 98, and have not had a bit of trouble with it, but like what has been noted it needs to be set up right, it took me about 2 hours to get it right, and it is working good. I have heard that Mcloud has made up to three versions since 98. The third version a friend of mine just got has had major mods done to them, to help prevent the blowout of the o-rings. The second version is worse than the first version, so beware.

"SFI" as in fire rating? How so?

No, I think he means by cutting into the blowproof bellhousing and modifying it you would make it so it isn't considered as safe as an unmodified unit. That's how I read it, anyhow.

oh, yes that makes sense

That is what I mean't, S.F.I. is a rating system for NHRA and other sanctioning bodies, it is used for bellhousings and flywheels, it means that they will not break apart if the clutch or flywheel explode.
