Note. During installation, all cable ties must be re-installed at the same location. Secure all hose connections using hose clamps appropriate for the model type. During assembly, replace self-locking nuts and bolts. Always replace bolts that are tightened to torque as well as O-rings and gaskets. Clean input shaft splines and (in case of used clutch plates) clean hub splines, remove corrosion and apply only a very thin coating of lubricant on splines. Then move the clutch plate back and forth on the input shaft, until the hub can be easily moved on the shaft. Remove all excess grease.
