    Its not stuck in gear like I am used to...its a sm465 with the manual linkage. No idea on the age of the clutch but after this weekend's wheeling trip it has tons of slippage. I can't increase RPM's over about 500 at a time without it slipping. I tightened the luinkage to the tightest its ever been since I have owned the truck and yet it still slips....is it on its way out? Or just still adjusted improperly?

    After wheeling when mine would slip it was because it was full of mud. Go to a pressure washer and stick the wand in by the starter let it rip and see what comes out. If it still slips after that it is time to replace.

    I got one as well... /forums/images/icons/smile.gif Learned that from changing out the throwout bearing. Now I have learned I should have changed the clutch and all while I was in there...not looking forward to dropping everything down again to change the clutch out....

    When you take it to the coin wash and take the inspection plate off and have somebody hold the clutch down. THe dirt is between the clutch and the fly wheel and pressure plate. If you don't disengage the clutch then it will stay trapped in there.

    make sure your shorting the ajustment rod to the fork.
    if you still slip its time for a clutch.
    don't buy the diaphragm type.
    three finger is the way to go.
    Buy a matched set with the disc, spring plate and Throwout bearing.
    don't mix parts, buy it as a kit all together.
    put a new pilot bushing in the crank.
    check out your fork right away, and have the flywheel turned.
    I pull the tranny with the T-cast on with the front driveshaft on the T-case.
    seperate at the back of the bell, the four big bolts.
    leave the crossmember attached to the tranny.
    I take the seat out and the floor access plate removed to get the bell housing bolts out.

    I disagree on the three finger clutch comment. I have a diaphram clutch and it's the only way to fly.

    I was starting to wonder... I don't have the big bucks to dump into this thing right now! Hoping a new clutch can atleast last me a yr or two without any major dumping of the clutch.

    Any recommended brands out there?

    Go to NAPA and get a LUK heavy Duty clutch for a little over $110 or so...Good clutch and it will last a while...LUK actually makes all the Centerforce prussure plates (not sure about the clutch disc?) But that should work well for you...As usual, always remember a new TO bearing and pilot bushing... /forums/images/icons/wink.gif

    I agree, the diaphragm clutch can have equal or greater clamping force with lighter pedal feel than the Borg &amp; Beck (three finger). It is a superior design IMO.

    /forums/images/icons/smile.gifOk with your choice. I'v done every clutch change on my 77K10 rig. I bought it New. When I use it to pull a trailer through 8 miles of sand. I will only Install the Heavy Duty 3 finger. Been there, /forums/images/icons/mad.gif done it&gt;&gt; Diaphrams are for 2 wheelers and Birth Control. /forums/images/icons/grin.gif
