Parts replacement principle
1. Check immediately that any spare parts you receive have not been damaged in shipment.
2. Always work in a clean environment.
3. Wash all components in solvent and blow dry with compressed air before refitting.
4. Take care not to damage rubber seals.
5. Avoid damaging precision machined surfaces.
6. Components should fit into their housings without excessive force. If force is necessary, this normally
means that the component does not have the correct dimensional tolerances of is aligned incorrectly.
7. When hand pressure is insufficient, only use presses or rubber hammer to fit components.
8. Never strike components with steel hammers.
9. Steel bush must be fitted only with a suitable press.
10. Do not use hammers to fit bearings.
11. Always respect the direction of rotation when assembling components.
Preparation before disassembling
1Clean the surface of motor, and check if the surface has chip and rust.
2 Check model and factory releasing number on nameplate, if there is no nameplate on motor, check
factory releasing number at seam allowance of front cover.
3Fill in relative information on motor returned for maintenance card before disassembling, such as
manufacturer, applicable machine model, applicable working condition, motor model, factory releasing
number, factory releasing date, head and marks of fabricator, working parameters (pressure, rotation, impact
and the constant running time at the highest pressure) on main machine, total working time of motor and
reason for returning for maintenance, etc.
4Make sure the production is released from the factory as a whole and it is not disassembled after
releasing, otherwise it is not maintained.
5. If there is external leaking, do gas tightness checking to the entire motor and find out leaking position.
6Check tightening torque of bolts (screw down bolts again with torque wrench, record the Max. tightening
torque), learn if tightening torque of all bolts have reached the required specification.
