Most important – cleanliness.
All openings in the reservoir should be sealed after cleaning.
No grinding or welding operations should be done in the area where hydraulic components are being installed.
All cylinder, valve, pump and hose connections should be sealed and/or capped until just prior to use.
Mineral spirits should be kept in safety containers.
Air hoses can be used to clean fittings and other system components. However, the air supply must be filtered and dry to prevent contamination of the parts.
Examine pipe fittings and hose assemblies prior to use to be certain that burrs, dirt and/or scale are not present.
All pipe and tubing ends should be reamed to prevent restriction and turbulent flow.
Do not use Teflon tape on straight thread connections.
When installing pumps or motors, always align coupling halves as closely as possible, within 0.007 inch.
When using flexible couplings, follow the manufacturer’s recommendations or allow 1/32 to 1/16 inch clearance between the coupling halves.
Do not drive couplings on pump or motor shafts. They should be a slip fit, or shrunk on using hot oil.
Always use a dry spray-on lubricant on splines when installing. This prevents wear and adds to the life of the splines.
When using double universal joint couplings, the shafts must be parallel and the yokes must be in line.
When installing V-belt pulleys on pumps or motors, line up both pulleys as closely as possible. Always install the pulleys with a minimum amount of overhang as close to the pump or motor face as possible. This increases bearing service life.
