Assembly

• 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.
