Default Multiple Problems After Clutch Install.....

Here's what I installed:
~ New Billet McLeod Flywheel
~ Organic/Kevlar McLeod clutch w/ McLeod Pressure Plate
~ Updated master and slave cylinder
~ Drill Mod

When I first started the car up, it had trouble trying to idle, when I test drove it down the road, it was still having trouble trying to idle. Is this because I had my battery disconnected for a long period of time? Also, It goes into 1st, 6th, and reverse ok, but is kind of notchy.
I put new Amsoil Synthetic ATF in it. The clutch also feels like it isn't holding really well either. Does it need some breaking in before it starts to grab? Any opinion are appreciated.

Thanks,
Robbie Clarke

A few questions.
What are your mods?
Where is the engagement point of your clutch pedal?
Is the pedal spongy or is the engagement point inconsistent?
If you are sitting on a flat surface with the clutch pressed in and brake released, what happens when you rev the motor? Does it want to move?

My Mods are:
~ QTP LT
~ QTP Y Pipe with Carsound Cats
~ Loudmouth
~ MAFT
~ Intake w/ smooth bellow
~ Pro 5.0
The engagement point is right after I begin to let off of the clutch. The pedal feels a little spongy and it engages the same point every time. When I reved the engine, when idled back down, it was searching for an idling point, at one point, it went all the way down to about 300. It's weird because the car was running great before this, and after the install, it was acting funny. Car doesn't move when I rev it with the clutch in. Do you think there could be air in the system still, causing the notchy shifting and the feeling of the clutch slipping (hopefully just me)? Help me out!!!

Your engagement point is right off the floor?

What procedure did you use to bleed the clutch?

I was unable to get the air out of my clutch using the pump and bleed described in the shop manual. I bench bled the master cylinder?
http://www.phpinc.biz/clutchbleed.html

If you didn't bench bleed it, all is not lost because you can pull a vacuum on the resevoir and possibly get all the air out.

In any case, the clutch shouldn't be slipping if their is air in the hydraulics. Air makes it hard to get the clutch to disengage, which makes it hard to shift. It makes the pedal spongy and the engagement point will move around sometimes.

Are you sure that everything is installed properly and torqued?

I think your clutch is dragging. Jack up your car and secure your car safely on jackstands. Be sure that it is perfectly level so it can handle alot of movement. Get in the car, put it in 1st gear, and engage and disengage the clutch. Have a friend watch, if your clutch is dragging you will know because the wheels will move when the clutch is in. This is why your car idles down when your in neutral, the clutch is semi-engaged.

This will cause alot of damage to your synchronizers if driving it for extended periods of time. My suggestion to you would be to keep a constant eye on your fluid.. make sure you don't have any leaks. Try rebleeding the clutch/master cylinder a few times. You might try letting it sit and bleed for extended periods of time when you open up the bleeder. Or do what I had to do, and get an adjustable master to get rid of the notchiness and overall cruddy feeling.. Also check your hydraulic lines and make sure they are clear of air pump and exhaust.. This will cause an extremely notchy feeling.

Good Luck!

I did the pump, bleed, pump, bleed method. It just feels like it doesn't have the power is should with all the mods I have. I drove it around the block and when I came back, I smelt something but it didn't smell like a burnt clutch, it smelt like something else (maybe the brake fluid that overflowed out the reseivor or the clutch needs some breaking in?), could different friction pads on the clutch has different smells to them? I'm just scared to drive it around because if it is slipping, I don't want to burn it out so fast. I torqued the flywheel but didn't torque the pressure plate bolts, I torqued them the first time but I had to loosen em up and realign the clutch, so I retighten them I didn't torque em but I got em to where I felt like they were torqued. I will try jacking up the car and see if it's dragging this weekend. Right now I'm at the point where I just can't go in the garage and work on it because I'm pissed. Thanks for all the help guys.

Robbie

Pump and bleed method really doesn't work to good for the Mcloed master.You need the vacuum pump like listed above.Your clutch is dragging if it is grabbing right near the floor.I adjust the peddle to be a little above the brake peddle.
With the battery disconnected for long periods of time it resets itself which will cause crappy idle when first started.
Answer your own question about slipping.Go out and WOT some shifts and see if the car breaks loose.
The Mcloed clutch is a very soft hitting clutch.Pop it and it will hold.

My PP bolts backed out on me when I installed my SPEC S3 clutch. I had to pull the tranny and retorque and loctite the bolts.

I would try to use the hand vacuum pump and get all the air out first.
If that doesn't work, then you might have to loctite and torque the PP bolts.
