5-5-3) Cautions on Handling Taper Grip
1. Never use lubricants containing antifriction composition. It may reduce the designated transmission torque.
2. Always use a torque wrench when tightening bolt and apply designated torque in the order indicated in this maintenance
manual.
It may result in reduced transmission torque or loosening otherwise.
3. Do not exceed the designated tightening torque.
It may result in damages of bolt, taper grip, etc.
4. Tighten bolts regularly for safety.
4. Additional tightening after operation.
Check the tightening torque 20-30 hours after operation. Tighten again with designated tightening torque when they
seem to be loose.
Make sure to check the tightening torque in regularly, such as once every half year.
5-5-2) Taper Grip Removal
1. Loosen tightening bolt in the designated order slowly until they separate from the thrust collar of the spot facing hole.
2. Pound the flange of the taper grip lightly with a wooden or a plastic hammer.
Now, the reducer is free from the mechanical shaft.
3. Tighten two of the tightening screw lightly by hand.
This is for not locking the taper grip when removing the reducer from the shaft.
Remove reducer from the mechanical shaft in this condition.
Use the puller for taper grip flange when removal is difficult.
