Go with Tilton TOB. End of problems. It cost more, until you figure cost to fix or replace something else.

Lal,

In your information it says you are running a Chevy 350. The t/o unit is a GM type replacement? Assuming the quality is good (the manufacturer may actually be the one that supplied the unit for GM in the first place) it seems it should fit and work ok.

The Tilton and the McLeod units are good, and apparently can be made to fit lots of different applications, but if a GM piece fits a GM engine/pressure- plate/disc assembly, sounds good to me.

If at all possible TEST it before you button everything up to verify the release is adequate and it doesn't leak. Be sure to use a pedal stop and adjust it so you do not overextend the ram.

Just noticed I posted a little earlier on this thread...4 years ago! Where in the H--L did FOUR? 4? years go...? No matter, people still have the same problems.

Anyway, my late version McLeod t/o ~2002/3? still works fine. ~13,500 miles on the car.

Thanks Pete,

Yes I'm running a Chevy 350 with GM clutch and a Super T-10 transmission. I don't know if the t/o unit is a GM type replacement? but it is sold for many applications like the other HTOB manufacturers.

I actually had a Tilton unit, but I thought I wasn't going to use it, so I sold it on eBay. After a number of attempts with trying to fit an external slave and fork set up, I gave up to to lack of space.

I plan on doing a test before final buttoning up to verify just your points. A a pedal stop is in the plan. This HTOB has a built in stop to prevent over extension.
And the pedal stop will prevent over pressurization.

4 years? Where did 60 years go? I was just 25 the other day!!!

When you installed your McLeod TO. Did you have a preload the bearings against the clutch fingers? Or does yours call for a space?

I would double check on that T/O bearing, I mean...$99.00? That sounds pretty cheap. Just remember, if anything goes wrong, you got to pull the trans everytime to repair it. I've got a McCleod H/T/B and it's been working great for years because it's my only option. Are you sure you can't install an EXTERNAL slave to operate your clutch?

Tim I love the look of your cobra. The color is great! Is it a custom color?

And don't forget the $0.99 cents! I'm trusting that by now HTOB technology is no longer a Black Science. And that this manufacturer has made a good one.

I may eat these words in the future and then perhaps that would be a good time to install a new 5 speed. I'll let you know here on this thread. And if all is well, it may become a very old thread.

Did you look at the link to the product?

Thanks for your response.

Lal,

Looks like you just posted a few minutes ago...

OK, as I remember...I used ~.20" between the fully retracted ram, and the tips of the clutch diaphragm fingers before bleeding. Used a carpenter's square and straight edge to make sure.

When I was at the McLeod shop, the tech said it could be set up with as much as 0.25" clearance, even though the directions sheet said "minimum of 0.1, max .125" before bleeding the unit.

Ask around, maybe the Chevy service manual covers the setup for the truck unit in more detail...who knows if something is different...find out sooner than later.

I agree the Chevy type part at $99 is not necessarily a quality related issue. A stock Chevy truck service/replacement part may have had a few hundred thousand+? made...doubt the aftermarket race-car guys sell more than a few hundreds of each model they stock, so handling cost and markup are probably the big factors in higher prices for special fit hot-rod stuff.

Do test the thing if you can. Pulling clutches gets real old in a hurry.

Pete
