Tips: How to install the diaphragm coupling?

Wipe clean the dust and dirt on the surface of the installation shaft, and apply a thin layer of engine oil or lubricant.
Clean the inner hole of the diaphragm coupling, and apply oil or lubricant.
Insert the diaphragm coupling into the installation shaft; if the aperture is too tight, be careful not to hit the installation with a hammer or hard metal.
After the positioning is completed, first press the diagonal direction and gently tighten the screw with a torque wrench (the specified tightening torque 1/4).
Increase the strength (1/2 of the specified tightening torque) and repeat the fourth step.
Tighten the tightening torque according to the specified tightening torque.
Finally, tighten the fixing screws in the circumferential direction.
When disassembling, please proceed with the device completely stopped, loosen the locking screws one by one.
