Hydraulic Hose and Fitting Torque Specifications
Your machine is equipped with Parker Seal-Lok
®
O-ring face seal fittings and hose ends. Machines that
utilize Parker Seal-Lok
®
O-ring face seal fittings and hose ends require that the fittings and hose ends be
torqued to specification when they are removed and installed or when new hoses or fittings are installed.
Torque Procedure
1 Replace the O-ring. The O-ring must be
replaced anytime the seal has been broken.
The O-ring cannot be re-used if the fitting or
hose end has been tightened beyond finger
tight.
The O-rings used in the Parker
Seal Lok® fittings and hose ends
are custom-size O-rings. They are
standard SAE size O-rings. They
are available in the O-ring field
service kit
(Genie part number 49612).
2 Lubricate the O-ring before installation.
3 Be sure that the face seal O-ring is seated and
retained properly.
4 Position the tube and nut squarely on the face
seal end of the fitting and tighten the nut finger
tight.
5 Tighten the nut or fitting to the appropriate
torque per given size as shown in the table
above.
6 Operate all machine functions and inspect the
hoses and fittings and related components to
be sure that there are no leaks.
