If it is sticking/hanging any @ all it can cause misadjustment. Start the engine and lift up on the brake/clutch pedal then cut off the engine. NOt sure why deere tells us we have to remove plug and use the starter motor. Can you accidently crank over said engine/start it while tightening that bolt down??
Obviously, do this as opposed to removing plug and turning engine over and over with the starter. Every-other step is same and do them in proper order.
The spring is adjustable, but all the adjustment in the world will not cure a pinched center hub. It must move free w/o hardly any wobble.( A worn out center hub bushing will move freely side to side but will not operate)
I have installed old/rusty variator clutch assemblies that work just fine as opposed to one that is polished and worn-out.
