Hydraulic TO Bearing and clutch pedal travel Help... - Lateral-g Forums

Tom,

Personally I think a gap of .210" is a little much. I use a Quarter Master bearing which doesn't have nearly as much maximum travel as the Ram or Howe, so for me, every bit of travel is important. I set my LS7 clutch with about .100" air gap. The LS7 clutch is nice in that the springs don't have to move very far to achieve full release. I am using a .700" MC and have about 2" of pedal travel before the clutch starts to bite.

Since you will have to remove the trans, I would suggest rebuilding the Ram bearing, if a rebuild kit is available, and reducing your gap to about .100-.125"

Thanks Andrew. I think agree about closing the gap more. I may still spend the money to get the heavy duty Ram TBO in hopes that it may last longer because flat backing a trans sucks!

I have not had a chance to dig my notes out and look. I apologize. (I am reading/writing this while attending a phone meeting at work!) If I remember correctly, the RAM website has the installation instructions that you can print. I will do my best to get something tonight. If it is leaking, my guess is your travel on the clutch pedal is greater than the travel on the RB. It causes it to force fluid pass the o rings. As Andrew said, remove and rebuild (kits are cheap $13 or less) How ever, unless someone has a trick to install an o ring on an INTERNAL undercut, your best bet is to send it back to RAM and have them repair it. Ask me how I know.

Must be the nature of internal HTO bearings. Mine, a Mcleod for a T5 did the same thing. After messing with it for 2 years, I finally threw in the towel and went with an external slave. So much nicer now that I can make adjustments without having to rip the bottom of the car apart to do it.

Anyone want to buy a used McLoed unit?

Tom,

I would look into the Howe TOB. I like its design which incorporates a travel stop. It is also advertized as having up to .750" of travel. My Quarter Master TOB has also been quite reliable. The only time it failed is when I over-traveled it which cut the seal. The downside to the Quarter Master TOB is the rather limited travel. Thankfully my LS7 clutch doesn't need much for release, but some clutches may need up .5" of travel at the fingers to fully release. I don't have first hand experience with the Ram or McLeod, but the reviews online seem to be mixed at best.

I pulled the trans tonight and it looks like the inner seal came apart?
The travel stop is intact so I am not sure what happened. I think I will replace the bearing because I am not really sure how to get the bearing apart

2 things happened.

Overstroked, causing the fluid to push past the o ring -or- the o ring was damaged on installation when putting it on the input shaft. Either way, call RAM, talk to tech and send it them. They will inspect and rebuild for you. Trust me, it is a ton easier to have RAM do it than do it yourself.

I cannot find my cheat sheets for my install. I must have put them away so i would not loose them and lost them. I will keep digging.

Good Luck. I do have extra shims if you need them however.
