the center spline of a clutch is the base plate for which the clutch is made. You have a disk usually from 7" to 14" made from treated steel then the clutch material is rivited to the plate / with or without addhesive. Your clutch is a floating disk on the splined input shaft of the transmission, and rides between the flywheel and the presure plate.There is a throwout bearing on the input shaft as well. Your throwout bearing is attached to the motion of your clutch pedal through a forked arm either through hydrolics or simple mechanical leverage setup.

Clutch disc? If this is what you are asking, it looks like a plate with an abrasive surface on both sides. In the center is a "splined" hole. Hope this helps
Most certainly BUT it has to be replaced with the same type of disc and spline

clutch pedal free play decreases
If the disc is installed correctly the clutch will engage and disengage smoothly. In most cases if the disc is installed backwards the clutch disc will bind against the flywheel/crankshaft bolts and not release resulting with a clutch that doesn't disengage. More than likely if the disc was installed backwards the disc is now damaged and will need to be replaced.
The disc brake caliper is attached to the steering knuckle or spindle.
You replace it. The oil is in the clutch face and if you use it, the face will come off of the disc. There is no way to clean it.
there is a tool that aligns the clutch disc with the pilot bushing to center it so that the input shaft will line up with the splines in the disc and pilot bushing. These are usually included with the kit which should include the tool, disc pressure plate, pilot bushing, throwout bearing, maybe spline grease. Also, lube the end of input shaft (go easy on the grease) and throwout bearing ball pivot and throwout bearing sleeve(what it rides on). Also when installing new bushing, don't use a punch to install or you will pean over edges and play hell getting input shaft in (use driver tool). Don't get any grease on the disc. Have flywheel resurfaced.
Clutch disc is worn out. Not knowing what vehicle you have, most are hydraulically operated and there is no adjustment. Time for clutch replacement.
no adjustment on hydraulic clutch, worn clutch disc and pressure plate
