Need Help adjusting clutch on B

I am at a loss with what to do with my clutch on my late model B. I can't get it adjusted correctly to engage with any force. I engage the clutch with adjusting nuts loose. I then tighten the nuts and it takes force to disengage it and I here that snap . But when I try to engage it again, it will not engage no matter how hard I push the lever. If I loosen the nuts a few turns, I can get it to engage again, but not with a pop or any force, and just the weight of the lever will disengage it.

i changed the operating sleeve to one with no play in the drive pin hole since I thought that could be my problem. The clutch dogs and toggles and adjusting bolts all look good, but maybe i am missing something here. I don't want to spend the money to replace all those parts if I don't have to, but I am at loss what to do next.

Will having new dogs and toggles and bolts make a difference in adjusting?
 
It can be challenging. If you have an operators manual and follow the procedure in there it will usually work. Also, you have to have the clutch pulley brake adjusted correctly.
 
No , have not started the engine because I have the wheel off so I could remove the clutch pulley. How would starting the engiine make a difference in the clutch adjustment?
 
You say you adjusted the nuts a few turns? For adjustment of the clutch, 1/4 turn is a lot. Here is how I adjust my two cylinder clutches. (A-B-G&A) Loosen up the three nuts and engage the clutch lever. Tighten each nut a little at a time, evenly until you feel some resistance. Get a good torque wrench, tighten each nut to 12 FP. Go around again and loosen each nut slightly and re-torque to 12 FP. This is to be sure each nut is tightened evenly. Release the clutch. Engage the clutch. If it releases hard or engages hard, loosen or tighten each nut by one castelation at a time until it feels right. I should snap in evenly and release smoothly. Adjust the pulley brake to stop the pulley after the clutch releases. The pulley brake will require some experimentation.
 
Did you have the three T-head operating bolts out; and clean the holes out with a drill bit??You got the operating sleeve tab and pin tight; that is important. If all is adjusted corrected, then it is dog and toggles.. That is what gives you snap.. I know they are expensive; plus $160.00. Do you know history of the dog and toggles; as; how old??
 
Pappy's explanation is the best I've seen here. About the same as I've done but without the torque wrench. Make sure the nuts turn freely on the threads. Start by holding the pressure plate against the linings while you turn one nut at a time. Pull out on the stud and wiggle it back and forth to be sure the T-head is seated while you turn each nut till it's just snug, with the lever engaged, of course. When they're all snug tighten each nut a bit, all the same amount, till you get the feel you like.

The dogs and toggles are the original and have never been changed. I just ordered a new set of dogs and toggles and pins today because I am out of options what to do.

When you say the tab of the operating sleeve , what do mean?

Last week I took the clutch pulley to a tractor repair shop where they replaced the my operating sleeve with a good one with no play in the drive pin hole. So now my operating sleeve can not move side to side.

I did what you said abot torquing them to 12 fp today and the clutch snapped hard when I disengaged it. But no matter how hard I pushed the lever, it would not engage again. So loosened each nut one castelation and tried again and again until I could finally get it to engage. But when it got to the point to where I could engage it agin, it took hadly no force to engage it, and just the weight of the lever falling back would disengage it.
 
I call the piece on the operating sleeve with the hole in it for the pin -the tab.. Your hole and
pin are good to go.. Dogs and toggles will fix your problem since they are old and worn.. Remember
to grease them and the pulley bearing.. A little grease on the pulley bushing to start..
