Thanks,how difficult would u say,once the two set bolts are out should slide off the pins right,the side with the lever should pull right out I think?

fjh Posted September 19, 2017 Share Posted September 19, 2017 (edited) Its q pain how ever with bolts out try get the non lever side out first it has no key! the clutch arm has to has to come off as you need to remove the woodruff key on this side and have to turn the shaft to get to it!once that is done the shaft will come out far enough to remove the fork! You will likly have to remove the rear motor mount to get the drivers side shaft past the frame! you have a CL it has thick mounts it will gain you loads of space Edited September 19, 2017 by fjh Quote Link to comment https://www.bigmacktrucks.com/topic/51022-clutch-release-fork/#findComment-380096 Share on other sites More sharing options...

MACKS Posted September 30, 2017 Author Share Posted September 30, 2017 Just a follow up, the bushing in clutch arm was missing or just worn out and he pin was worn real bad,way to much play,that's why I was having trouble adjusting it..

j hancock Posted October 1, 2017 Share Posted October 1, 2017 Glad you are gaining on it. Worn parts will make it tough to make a good adjustment. Quote JimIt doesn't cost anything to pay attention.

MACKS Posted October 1, 2017 Author Share Posted October 1, 2017 Got that right,an 1/8 of play = about an inch and half pedal movement by my uneducated calculations..
