I have a lakewood bellhousing on my 385 and stock hydraulics and clutch fork.

I cannot unscrew the adjustable pivot ball on the clutch fork enough to achieve the desired 0.120" air gap between the throw bearing and the pressure plate.

I cannot unscrew it enough because of my tko600 adapter plate.

People with lakewood bellhousings have you had a difficult time spacing the throw bearing accordingly?

As I understand it, a hydraulic clutch system has the release bearing riding on the fingers, since any excess tension will be relieved by the master cylinder. A non-hydraulic system needs the air gap as there is no provision for automatic tension relief.

The pivot ball should only be adjusted to correct the geometry of the bearing end of the fork. When the fork is perpendicular to the input shaft, you should have equal travel to fully engaged as you do to full rest. Any deviation will put a side load on the input shaft.

On a non-hydraulic system, your air gap is adjusted somewhere else in the linkage, not at the pivot ball.

i just threw mine together with all the stock stuff, works great.

The stock pivot ball specs is from the head of the pivot ball to the bellhousings flange which for a sbc or bbc is 4.750 use a straight edge on the bellhousing flange and mic. And if you have a lakewood explosion plate which is .125 you - from the 4.75 and lock it down. Now this is with the stock setup linkage not a hydrolic throwout bearing. Hope this helps I measure my pivto ball and it is 4.625" from the bellhousing. And I have the lakewood bell . I think the part number is 10520 I'll have to.look.

Thanks for that spec! I did run it using that measurement in the summer time however i was getting a grind going into reverse from neutral if i went into a forward gear then into reverse it would not grind. Essentially aligning the synchro.
My tko600 had a leak so tremec repaired it under warranty and investigated my reverse grind and came back stating it is my clutch setup cnot disengaging the clutch enough..

A T5 reverse gear does not have syncros. I would always shift into a forward gear to stop the clutch before going into reverse without grinding.
Does your tko600 have a synchro'd reverse gear?

... aligning the gears. (if no R synchro)

Is it a new clutch? If so, it might be a little "hairy" or at the very top of the thickness spec causing just a little drag.. just enough to grind into reverse.
Is it a well used clutch / does the flywheel have a ridge the clutch could be hanging on?
Does the clutch slide freely on the input shaft? If not, it could be "sticking" against the flywheel (since clutch pedalling lifts the PP off the clutch).

TKO isn't a synchronized reverse.
Forward gear before reverse is correct procedure.

I thought i had seen a synchro in the repair manual diagram, i may be wrong. Been half a year since i looked at it. Funny tremec will never tell you that is normal of course, but i have heard it with T5's so i do believe it.

This was tremec's update on my leaking counter shaft bearing retainer that I had fixed 3 times at a local shop before tremec finally took it back.
Funny he believes it had a synchro however I cannot find the reverse synchro in the parts manual so I believe there is not one. This gentlemen was not a tech either, he was a customer service dude.

MoJoe I do not have any concerns with my clutch disengaging properly, I guess you could say tremec has me brainwashed about it being my reverse grind culprit. But thanks to you guys I now realize it is normal procedure.
There are times where it wouldnt grind, however I stopped trying and just decided to live with going into 5th then reverse. She ain't no DD so who the **** cares right
