heck, just post your questions.

I know Felix and many others have experience with KEP.

just found out that crank has no 7/16 dowel pin and flaps does not stock it.

how neccessary is it ??

jim : )

[Crazyhippy]

Fairly... I'd wait and get one personally....

Any GOOD hardware stores around? Home depot might even have them.

how hard should the clutch fork be to move by hand ??

Jim

[scotty b]

Jim the clutch fork should be pretty hard to move by hand (assuming the clutch,pressure plate and bellhousing are all installed?) What you are attempting to do is engage ALL of the pressure plate fingers with no more than the pressure from your hand. Not gonna happen! Linkage and leverage werk wonders ! So are we gonna have an install party or maybe a group ride party?? (IMG:style_emoticons/default/beer3.gif)

[Dr. Roger]

clutch fork? U mean when the engine and transaxle are mated?
that should be very difficult.

If you're talking about when the clutch fork is free, then it should be easy.

harmonic balancer pin? Mandatory. =-)

[jimkelly]

scotty
roger

yes - we had tranny mounted to engine and the first thing we noticed was that the fingers on the pressure plate moved to almost flat position versus outward towards the tips of the fingers which seemed odd ??

We tried to move the fork by hand and with a pipe on the end of the fork but it seemed like we were gonna break the fork if we pulled harder??

going without pin unless i got some wrong kep parts.

Yes it seems backwards but it is actually correct. The fingers move inwards and release the pressure from the cltch disc. This ensbles the disc to spin freely of the flywheel, thus allowing you to change gears. When the clutch pedal is released the fingers put pressure back onto the clutch disc and transferring the load back to the drivetrain.

[scotty b]

OOPS I just re-read your post. Were the fingers depressed BEFORE you tried to engege the fork?

[jimkelly]

the fingers are already depressed when tranny is not even connected to the engine but pressure plate and clutch disk are bolted flywheel on the engine. The pressure plate when not mounted has outward fingers but once bolted up to engine they get paralell to the kep adaptor plate - aka depressed.

we are juts now replacing the studs in the tranny housinf behind the throw out bearing - as mayne the fingers are designed to go flat but we needed more travel??

[Dr. Roger]

when the pressure plate is bolted tight to the flywheel the fingers are supposed to be under pressure. the clutch plate is being squeezed.

when your transaxle/engine/clutch cable assembly is installed, your clutch fork will push those PP fingers and release the clutch plate.

[scotty b]

Yes the fingers do pull down when your torque the mounting bolts down. How much on a SBC I'm not sure, but if the correct pressure plate is used and the correct torque is applied there shouldn't be aby worries. IIRC the fingers on my Jeep clutch were almost parallel and go concave when the fork is pressed.IIRC (IMG:style_emoticons/default/blink.gif)

[Dr. Roger]

i made the mistake of mating my engine/trans without torquing the PP.

what i found was that the cluch fork wouldn't allow me to mate the engine/trans due to the PP fingers not being pressed in by torquing them down.

so there U go. =-)

[jimkelly]

thanks guys

just added some pics to my blog

http://www.914world.com/bbs2/index.php?aut...blogid=312&

will call KEP first chance

using a 12 inch piece of pipe over the clutch fork I can pull/push the PP fingers forward between 1/8 and 1/4 inch - maybe with a differnet pipe some more?

jim

[jimkelly]

bump - can't install assy into car until i know the force to move clutch fork is typically really high ???

[jimkelly]

i got a tip that 1/4 inch movement at the pp fingers may be about right.

so possibly that fact that they are parralel to the kep plate once the pp is torqued to the flywheel may be typical.

actually it was not good as Mr Kennedy proposed a double disc for my Jaide 8" clutch but his employees said otherwise. I changed everything to Renegade 9". I'm sure KEP would have worked but I had mostly Renegade parts and wanted to stay consistent.

Andyrew and Nick Mirinov used KEP, they may help if you PM them. If they are not online, search their threads

a few pieces of advise:
check the mount screws under the clutch arm don't interfere
make sure the TO bearing is positioned in the arm fork when mating the tranny
the arm should be tight but not so much the clutch cable cannot move it - a long pipe has more force than your foot... (IMG:style_emoticons/default/smile.gif)

[jimkelly]

thanks,

after we realized the mistake - we replaced the studs/nuts that hold the front tranny seal cover on with the supplied small bolts provided by KEP - but this is not what we think our problem is.

The TOB is in the clutch fork once it is mounted to the tranny - can this come apart during tranny attachment?

we have about 1/2 inch of free play in the clutch fork and then move up against the fingers of the PP the pipe can move it forward some - somewhere about 1/4 inch which puts the fingers almost concave or concave - need to look at it again closer.

thanks again

Hey Jim,

Travel of the fork can be a real pain in the butt, and you are right to be concerned. I had my trans out 10 freaking times before I got it right. A couple things you need to look at:

1)Make sure you have a Stage 3 or lower clutch combo. The guys at KEP sold me a "Stage 4" clutch package, and guaranteed it would work in my application. After installing in the car, I couldn't get the damn thing to release. I tried everything in the world to get it to release (bend the fork, grind the fork opening in the bell housing etc), with no luck. Then I talked to Scott at Renegade, and he told me that no matter what I did, a Stage 4 will never work in a SBC 914. So I sent it back, got a Stage 3, and everything worked fine on the first try. (BTW, Renegade sells the KEP stuff)

2) Make sure you have removed all the spacer washers from underneath the fork pivot ball. If there are any under there, that will reduce your fork throw. Keep in mind the ball threads into a hole that goes all the way into the trany case, so I would recommend putting sealer on the threads before re-installing.

Good Luck, and Merry New Year (IMG:style_emoticons/default/beerchug.gif)
