Main operations:
GENERAL SUGGESTION
1. Check the parts have not been damaged during the
shipment.
2. Work in a clean area.
3. Clean with solvent (except the seals) and air dry all
components before assembling.
4. Pay attention not to damage the machined surfaces.
5. The components need to be fitted in place without
forcing them. If too much force is required, it is due a
bad clearances issues.
6. When hand pressure is not enough, use only mallet
and never hammer.
7. Respect the tightening torque for bolts.
