clutch in 4106

[jimsflx]

just put new clutch in 4106 and it will not go into gear when it is ideling but shut it off and put in gear and restart it shifts great when it is setting still and running it does not release. put it in gear and it will not come out of 1 st gear. or go into reverse. eny thoughts? thanks jim

 Obviously its not releasing properly,, are you using a "mousetrap" or other "helper" devise?? >>>Dan  (Did you install a "spot clutch",,full face type or a wet clutch??)

[jimsflx]

no mouse trap or other device. got the clutch from tampa cluctch they have done these before. a friend of mine put it in that might have been a mistake? he has done gm and eagles before. you are right it is not releasing.my friend swares he put it in right i did pay him for doing this. if you start it in gear and start moving it shifts fine. will not goe into gear when idling. thanks jim

 If you have the engine running and push the clutch to the floor,, at what point does it begin to "take up" or ingage??
If its near the floor, than it can be adjusted up for more release,, if at the top of the stroke that you have another problem.>>>Dan

The clutch finger heights are off.  BTDT.  I measured twice and STILL got it wrong!!  I finally converted the measurements into millimeters and, yup, it was off. 

I don't know if you can adjust the finger heights while the tranny is installed.  I'm sure anything is possible, but measuring would be the challenge.

dan we ajusted the peddle so it would engage both ways,doesnt make any differants. mark we have done the ajustment,yes you can do the fingers from the bottom. luke says 1&38ths from the finger tips to flywheel. so we have tryed to get maesure but still will not release. thanks jim

 Are the parts you have installed now the previous parts?? or have you replaced with new parts??  Were the fibre plates relined, and with what??(Heavy duty organic or Kevlar??)  The center driven plate could be binding in the splines and the fibre plates can be installed only one way.>>>Dan  ( I just installed a new clutch in Red Riders 4106 two weeks ago and it works like butter) You may have a trans removal in your near future     YUCK OUCH !!

[OneLapper]

Did you measure the discs and center plate?  IIRC I measured everything after the machine shop resurfaced the flywheel & plate.   That affects the stacked height, which I had to determine if it was all within spec.   I took careful notes when I put all together, just don't recall what I did with those notes!!!  Must be in my bus receipts pile.

If the pressure plate was resurfaced, it will need to be shimmed.

[Utahclaimjumper]

 If the pressure plate or the flywheel had been resurfaced, his problem would be the opposite,, slipping for lack of pressure..
The entire clutch must be assembled, then adjust (if necessary) the release fingers. This process assures the correct clutch pressure and release movement.>>>Dan  ( It appears the mechanic has not done this job in the past,, time to have a talk with him)

I really have a hard time with people fighting the 4106 clutch me I would toss the flywheel and use a different flywheel and change over to a mushroom type clutch they work good in a 40 ft bus one should be fine in a light weight 4106 would make life so much easier for you GM and no Luke or Ted don't agree lol

I have to agree, the dual disk setup is less than elegant solution nowadays. The South Bend clutch on my Dodge dually is rated to 1100lbft and its as smooth as silk.  You would think someone has made an improved design in the last 50 years!

The thought of switching to a completely different setup never even occurred to me.   Next time!

  The one & three eighths inch measurement is from the finger contact points to the OUTBOARD FACE OF THE PRESSURE PLATE HOUSING,,,,not the flywheel... and that measurement is made with the clutch fully assembled to the flywheel.>>>D

Fine, Clifford.

Now really help us out by providing part numbers and sources for all the components necessary to make the change-over.

thanks guys. he is pulling the trans tomorrow,these where all knew parts. we replaced everything. i am with you rj i had no idea you could change to a newer type clutch, i would do that in a heartbeat.
