Twin disc problems

I replaced the ceramic clutch with an hks twin disc and after getting it warmed up pretty good i have a problem getting it in first gear!
I seem to have plenty of free play and the clutch ingauges more than 1/2 way up but if i stop i have to fight it into gear!
It was ok until i got on it and went from 2nd to 3rd and it started slipping i thought i must have had a little grease on my hands when it was installed.

One thing for sure it doesant slip any more!

I would be gratful for any help! Thanks.

is ur idle high? In theory your clutch should have nothing to do with gear changing... and for sure not 1 specific gear... maybe your idle is higher, and your first gear syncro is starting to go?

I dont thing so it idles at 1000.00 rpms but this affects getting it into any gear while your setting still. I really have to jam it to get into gear while stoped but when running its better of course.
It also doesant try pulling when stoped and engauges pretty normal!
Ive had clutches that didnt disengauge right but this is diffrent.

No: The fork is fine and other than not wanting to go into gear when your stoped it shifts ok not great but ok.
I cant feel any clutch drag when setting in gear idleing either. I was told i could use the stock throw out bearing and it snapped in ok.
If i adjust the clutch rod i can make it pull further but it was ok until i got on it and it slipped and then didnt slip any more.
I dont like makeing random adjustments until i get an idea whats wrong.

Ill try adjusting becouse the master and slave are almost new and working perfect the day before.
Whats got me baffeled it was disengauging fine then after the clutch started slipping and then started not slipping the problem started. I might meed more travel on the pull style clutch i guess.

What kind of shape is the pilot bearing in? If it is dragging it will keep the trans spinning and not let it go into gear. Also does it make any difference if you only apply the clutch half way? If you got it super hot it may have warped a disc and not allowing it to fully disengage.

Just my $0.02

Pilot bearing? If you mean throw out bearing it almost new. The trans input shaft bearing the same age. I dont know about 1/2 pedal when it started acting up i knew better than to start looking at it to hard i was hot and getting pissed after two days of replacing everything under the car.
You know that sick feeling in the stomach!
Ill take a more technical look at it after some sleep. Thanks.
More ideas are welcome.

ok , try this when you get a chance . car running pump the clutch real quick a few times and on the last pump as you press it engage the tranny and see what it does . it could possibly be either hte system cought air or the master or slave bleeding back.

Good idea tried it already no luck plus the master and slave are almost new.

Ill sleep on it and give it a better inspection tomarrow ill look in the inspection hole and see if all the parts are still were they should be!!!!

One of the things thats odd to me is that when i let out the clutch when i force it in gear it ingauges about 1/3 the way up not on the floor like you would expect!
Thanks again.

Sounds like a pilot bearing issue, did you replace it with a new one before your install?..

I guess it could be but the one in it has only about 2,000.00 miles and it wasnt doing this until i did a 2nd gear pull and when i shifted into third the clutch slipped and i let off tried it again and no slipping but then the getting it into gear problem started!

No, he means the pilot bearing. The bearing that's pressed in at the end of the E-Shaft.

Well i took a look tru the inspection plate and it looks like the center plate is installed backwards.
We had no instructions and my friend said he knew how it went.
Does anyone have instructions. In the hks web site the pieces are layed out and the center plate is diffrent than installed.
Thanks.

I'm also going to import face off but with my 4 door civic I can't bring my car cause my wife and kids want to visit my sister in Overland Park. Hope you get the clutch issue fix and I'll see you next week in KC.

Ill see you there James.

On hks website it shows the exploded view of the clutch and the center plates backwards as its installed. There is a high tension spring thats suposed to press aganist the flywheel when the clutch is pressed there fore pushing back the center plate and alowing for disengaugement. I dont think any thing is damaged but its getting fixed monday. The slipping was probley caused becouse there was 4 mateing surfaces that werent mated.

Thanks for everyones help.
