All that's needed to do job in sled is a large washer that will fit over the clutch retaining bolt and press against the cover. Then just remove the retaining bolt, install large washer and use it to partially compress the clutch.

Must remove belt first.

Apply just enough compression force to allow removal of the six bolts holding the clutch cover.

Once removed, unscrew the clutch bolt, gradually releasing spring tension. Now cover and spring can be removed. Weights can also be removed.

Use a dry marker to place an alignment mark on the cover and the movable sheave to make sure the cover goes back to its original position and maintain balance. There are Xs on the cover and movable sheave to do this, but can be hard to see.

Do not over torque the cover bolts. Torque the retainer bolt to 80 ft lbs.
