Pay attention to the following items when installing universal joint:
1) The universal coupling is delivered as an assembled whole, so it does not need to be disassembled and cleaned before installation;
2) The universal coupling shall be hoisted in a horizontal state, and hemp rope or nylon rope shall be used for hoisting;
3) The fork heads at both ends of the spline shaft and spline sleeve should be in the same phase;
4) The anti-rust paint, grease, rust and dust on the flange assembly surface shall be removed;
5) The flange coupling bolts can only be put in from the flange side matched with the universal joint, and the nuts are tightened by the flange side of the universal joint.
