    clutch not fully disengaging

    by o7crf450r » Mon Sep 10, 2018 6:36 pm

    Ive got an 07 crf450R, I was having issues with the clutch so I swapped out the clutch plates.

    Now when I pull the clutch it doesnt fully disengage, cables are tight, I replaced the springs and plates with the same ones that were in there.

    It seams like the Lifter rod Isn't pushing the pressure plate far enough???

    Were there any grooves on the basket where the plates slide?

    Welcome to the site !! \:D/

    It is possible that the actuator lever has somehow lifted slightly and the push rod has slid under it which means it would not be moving when the actuator does , it would then not be able to push the lifter rod far enough to disengage the clutch plates , so what i would do is move the actuator (with the clutch cover off so you can see what its doing) , and see if it pushes the plunger out any , , if it does not , remove the clamp that holds down the actuator where the cable connects , then lift the actuator a bit , then try to pull the rod out a bit and then push the actuator down as far as it will go , then push the rod back in and turn the actuator again , and see if the rod moves now , if so then put the clamp back on and make sure it is holding the actuator down all the way and there is no upwards movement if there is a gap/slop , then bend the clamp down so it holds the actuator tight down (so it has pressure on it), hopefully that solves your issue .... 8-[

    Thanks man, I didnt even think to check the actuator. Took it all apart, the actuator had a ton of play and was super worn down so I replaced it and the lifter rod, seams to be working.

    Glad it worked ;) , yea , most people go straight to the clutch itself for answers , and forget there are other parts that affect how it functions as well :lol:
