11.1 Preparation documents
Note:
Worm gear and worm wheel shall rotate flexibly without stagnation or single side tightness, while the worm wheel
shall allow certain axial movement. Machine oil pump O shape gasket shall not cut the edge.
Machine oil pump plugs shall not leak and sealing gasket shall be normal.
After installation, remove bolt 3 in trial running motor, and lock it when machine oil runs out continuously.
Use of the lubrication system:
Function of the engine lubrication system is to supply lubricant to component surface, transforming the dry
friction on the surface to liquid friction among the lubricant particles, in order to reduce wear of the components;
cooling components with higher heat load; absorbing the shock of bearings and other machine components to
reducing noises; increasing leak tightness between the piston ring and the cylinder wall; clean and wash away the
impurity on the surfaces of components.
