Slipping clutch problem question again

[MadmikeX3]

Hello i recently Bought a new stage 1 F1 clutch and had it installed beacause my previous clutch went out and wasent grabbing and i thought i just needed a new clutch so i got a new one. Drove it fine and broke it in for about a 1000 miles and it was still slipping some so i bought a new Master and slave Cylinder and got rid of the lil pressure loop thing that people say to get rid of. So all of that is done but when im driving and say im in 3rd 4th or 5th and i gas it it will rev up and accelerate slower than the tach is. Im not sure what it could be but hell who knows mayb i need a New Nismo Tuned 6spd?

did you put grease on the throwout bearing or anything like that? other thing is the throwout on the carrier all the way?

is it only in 3rd+ gear or does that happen in first and second as well

as out of town when my mechanic did it but yea it mostly happens in 3+ gears. ill ask him tommarow. Could it be that it needs adjusting?

If there is not enough clutch pedal free play, then it could cause the clutch to slip.

Check the clutch pedal free play. It should be 1.0 - 3.0 mm (0.039 - 0.118 in). Hold a ruler against the floor and up to the top of the pedal pad. Take a reading on the ruler at the pedal pad in the resting position. Now push on the pedal pad very gently until resistance is felt; at this point take the new reading on the ruler. Subtracting the two readings will give you the free play spec. To adjust the clutch pedal free play, adjust the pushrod for the clutch master cylinder which is located under the dash at the top of the pedal assembly. The pushrod has a locknut which must be loosened. Now the pushrod can be adjusted.

I have the same problem with you Mike. Did you figure out the solution? I also replaced my clutch, bypassed the Damper, Bleed a lot and adjust pedal. Can you share how did you fix yours? Thanks.

As a disc wears and loses thickness, the clutch slips .... but that's not all, the pressure plate (which clamps the the disc to the flywheel) overheats and its springs weaken. Also the flywheel is wearing ... losing thickness. And the shift fork loses metal on the contact surfaces over time. All this wear "stacks up" and keeps you away from original performance.

So when you repair a slipping clutch, you might want to use a check list similar to following:

1. Replace (a) pressure plate, (b) clutch disc, (c) throwout bearing, and (d) shift fork with associated retention springs.

2. Upon inspection, remove and have flywheel refaced if required.

3. Upon inspection, replace pilot bearing if required.

4. This is a good time to replace any questionable hydraulic components ... but there's no rush, as these are accessible when the clutch is back together.
