Clutch adjustment question
« on: September 04, 2021, 08:48:58 PM »
Ok, so I've been adjusting our clutch a little bit at a time but it doesn't seem to be making a significant difference.  At least not that I can tell, it may just all be in my head.  When sitting behind the clutch and looking towards the front of the vehicle, do you spin the clutch adjustment ring clockwise or counterclockwise to tighten the clutch up?  I've been adjusting the ring clockwise.  I haven't seen any posts or data in the TM's explaining which way to go.  I just assumed clockwise would take up the slack.  Maybe I'm not turning it enough.

Turning the ring clockwise, by way of the spring levers it essentially decreases the space between the flywheel and the pressure ring, making the clutch grab sooner off the floor and giving more free play in the pedal.

Ok, that's what I thought.  Thanks for the confirmation.

Follow up question.  When adjusting the clutch, would you think it would only need to turn a couple of "tabs/spaces" in the clockwise direction, or are we talking a full turn?  The clutch doesn't engage until the pedal is about half way up.  The disc is in good condition.

Just a few notches one way or the other makes a pretty big difference. The specs call for a min. 3/8" to max. 1/2" space between the front face of the throwout bearing and the spring plate hub. If your disk isn't too worn, that should give you about an inch to an inch and a half of free pedal travel.
