What Causes Clutch to Drag.

[RICK LAKE]

jhv48 JH couple of things that need to be checked, Lets start with air gap, you need .038" to .050" with the clutch pedal engaged. This measure ment depends on the pressure plate being a diapham or 3 finger setup.
If you have the correct clearance then you are looking at bellhousing alignment to see if it is centered on the block. If not under .003" you need to have it centered. Lakewoods are real bad for off centered. Once this is done have washers welded to the bell to keep it centered if you every have to pull it again. If you break the motor and get a new motor, remove the washer and center the bell housing on the new motor. QuickTime bell housing are very close to being centered on most blocks.
For pilot bushings, I like bearings better but bushing work. You have to make sure the bushing is not too tight on the input shaft of the trans. Use a little grease on the bushing when the trans goes back in the car. If this all checks out you are looking at the trans for internal problems. 1 other thing to check is the length of the input shaft of the trans. If you have a GM input shaft, it could be too long and rubbing on the end of the crank shaft, and wearing out the thrust bearing for the crank. If you are running a lakewood bellhousing, some trannys need .380" cut off the end of the input shaft. The teeth of the input shaft could be also dragging on the bushing too. Last idea is to replace the fluid in the trans. I am going with you have worn out the clutch enough to have it drag. Rick L. Ps you can also over extend the pressure plate in the clutch and cause the same problem. Your clutch pedal may need a stop too.
