question 1:

Isn't there a specific way the clutch pressure plate goes on?

the service manual says to orient the pressure plate so the white paint dot is opposite the white paint dot on the flywheel for balancing purposes.

My new Exedy clutch kit came with a pressure plate but it's not marked at all.

There is a small welded on square which I assume is a balance weight but my old OE clutch has two of these squares and the white mark is nowhere near either of them.

 

question 2:

Now that I've got my clutch out and can compare the old disc to the new one, it doesn't look like the old one is that far gone yet!?!

I can still see the relief cuts in the disc friction surface; although very shallow they're still evident. I was expecting to see a lot worse since the clutch was noticeably slipping on me last time I drove it.

 

question 3:

The flywheel appears to be in great shape as well, I can still feel the corduroy grooves with my fingernail. Should I still have it machined?

 

The pilot bearing and T.O. bearing are both tired, so regardless, I'm still replacing the whole package. Just wondering why the clutch would slip when there appears to be lots of material left on the disc...

Possibly the pressure plate sounds like. Otherwise might as well just replace everything while it's apart.

Pressure plate can be glazed. The pressure plate can have weakened springs. The disc can be glazed.

 

Do not forget to get new clips for the TO bearing.

your new kit may have "holes" marking it instead of paint.\

 

maybe your old clutch was just out of adjustment.?

On a hydro clutch? I thought adjustment was only for mechanical ones.

hydro is not adjustable.

did not mention car model.

I would say a worn pressure plate/defective pressure plate, or else glazing.

Clutch discs are not always worn beyond the grooves in the friction material. With proper use the pressure plate generally wears out first. It loses spring pressure so it doesn't clamp on the disc as tight as it should.

A Hydraulic system can also have a weak slave or master and cause it to slip as well.

Seems to me that all the hydraulics in a hydraulic system are only for releasing the clutch. I guess if the slave cylinder ram was not returning,it could cause the clutch to slip.

No holes or anything other than the welded 'square' to indicate balance.

 

Any other suggestions before I mount this more-or-less in a random orientation?

Nevermind, I just called ClutchCity and he said there's no mark to worry about and he's never seen one on an aftermarket pressure plate.

He said since they're externally balanced (hence the spot-welded square)you can mount it in any orientation as long as the dowels are lined up.

If the free play in the clutch pedal is not adjusted correctly it may not allow the clutch to engage fully. If there is no free play it could keep the clutch slightly disengaged and slipping.

Don't worry about it. It will be fine any direction.
