These torques are not recommended for tubes 12.7 (1/2 ) and larger with wall thickness 0.889 ( 0.035 ) less. The torque is specified for 0.889 ( 0.035 ) wall tubes each application individually . Before installing and torquing ° flared fittings, clean the face the flare and threads with a clean solvent Loctite cleaner and apply hydraulic sealant L OCTITE ® 569 the ° flare and the threads.

Install fitting and torque specified torque, loosen fitting and retorque specifications.

PIPE THREAD FITTING T ORQUE

Before installing and tightening pipe fittings, clean the threads with a clean solvent Loctite cleaner and apply sealant L OCTITE ® 567 PST P IPE S EALANT for all fittings including stainless steel L OCTITE ® 565 PST for most metal fittings. For high filtration / zero contamination systems use L OCTITE ® 545 .

INST ALLA TION ORFS (O - RING FLA T F ACED) FITTINGS

When installing ORFS fittings thoroughly clean both flat surfaces the fittings (1) and lubricate the O- ring (2) with light oil. Make sure both surfaces are aligned properly . T orque the fitting specified torque listed throughout the repair manual. NOTICE: the fitting surfaces are not properly cleaned, the O- ring will not seal properly . the fitting surfaces are not properly aligned, the fittings may damaged and will not seal properly . NOTICE: Always use genuine factory replacement oils and filters ensure proper lubrication and filtration engine and hydraulic system oils.

The use proper oils, grease, and keeping the hydraulic system clean will extend machine and component life.
