Default Installed new slave Cylinder ++

So drove around sub in 1st and 2nd was fine. Decided to go on the main road went thru 1st 2nd shifting at like 2000 2500ish. Go for 3rd bitch grinds like I tried to kill it. Like it wasn't lined up or something.. lose the clutch so got no clutch. Drift into yazaki.pushing on clutch pedal got nothing. Push it to the floor. Clutch back but engagement point really high on the pedal now. So I get it home. Bleed the clutch more. Like a whole bottle thru it.go back out. Was easy on it shifting no problems. So I get hard on it like 4500 shift. Goes fine. Go in a parking to turn around. All hard as **** to shift at higher rpms again

And I made sure it was lined up when i pushed the torque tube back in..

So Idk what that was .. any ideas?

did you check the bearings in the torque tube when you had it taken apart?

Pilot bearing keeps the end of the input shaft centered. Even if torque tube bearings were fried he wouldn't have these symptoms.

Pilot bearing was in. Bc when I installed the flywheel to the motor it would of just fell off the back of the block.

With out the pilot bearing.. when i stuck the flywheel to the back of the motor it would of never stayed in.. since the pilot bearings kinda holds it.. But ya its def in their.. So idk what the f is going on

I ran another bottle of dot 4 thru the line last night.. maybe air still in there? But that grinding sound makes me hella concerned..

That is completely wrong. The pilot bearing does not center the flywheel or hold it in place. There is a lip machined into the crank that centers the flywheel.

There are two styles of pilot bearings. A small needle bearing one and a larger ball bearing one. Mine is a 2005 and has the larger style.

Needle bearing style:


Ball bearing style:


Both


Here's what it looks like without a bearing installed

Ill have to check with the engine builder tomorrow then.. It would be on the motor not on the flywheel right? Lets say there isnt one in there.. could that be causing the issues?

that bearing stays inside the crank snout, so no... it wont come out when you remove the flywheel.
Now when handling the engine, if the bearing is worn and had a somewhat loose fit, it could have fallen out. I would assume if you had any crank work done, the machine shop would have automatically removed it.

question is, did he install a new one before putting it back together.

so...based off of what you are saying, the engine builder just built the shortblock and was completed by yourself and i am assuming you installed the engine yourself as well.

the engine builder would NOT have installed the pilot bearing during a short block build.

so unless you (engine installer) remembers putting that bearing in there, looks like its gotta come apart again.

Looks like you got answers already, but yeah, that bearing is a royal pain to get out without a bearing puller. Doubt it's falling out.

And yes it installs in crank. Gl with it.
