GENERAL / Tightening Torque IMPORTANT: The following items are applied to both fine and coarse pitch threads. 1. Apply lubricant (i. e. white zinc B dissolved Into Spindle oil) to nuts and bolts to reduce their friction coefficients. The plated bolts require no lu- bricant. 2. Torque tolerance is ± 10 %. 3. Be sure to use bolts of correct length. Bolts that are too long cannot be tightened, as the bolt tip comes into contact with the bottom of the bolt hole. Bolts that are too short cannot develop sufficient tightening force. 4. The torques given in the chart are for general use only. Do not use these torques if a different torque is given for a specific ap- plication. 5.
Make sure that nut and bolt threads are clean before install- ing. Remove dirt or corrosion, if any. Bolt Tightening Order When tightening two or more bolts, tighten them al- ternately, as shown, to ensure even tightening.
