I restored a '48 JD B. Engine runs well, but can't get the clutch adjusted. I replaced the crankshaft, pulley, clutch fork, bolts, and dogs with OK used parts, and used new clutch facings and drive disk. I set the crankshaft end-play to .008 with clutch installed, and proceeded to adjust the springs. After many trials and having the whole assembly off several times to check parts, I still can't get it adjusted. Either it's too loose that the clutch slips when it's in gear or it's too tight so that it doesn't completely disengage when I pull the lever back and brake the pulley. There has to be something straightforward wrong, but I can't figure out what it is. The lever never has the amount of snap that I think is OK. What could be the problem?
