Hydraulic Fitting Torque
Specifications
37 degree JIC, ORS, &ORB (REV. 10/97
This chart provides tightening torques for general purpose applications when special torques are not specified on process or drawing.
Assembly torques apply to plated nuts and capscrews assembled without supplemental lubrication (as received condition). They do
not apply if special graphite moly-disulfide or other extreme pressure lubricants are used. When fasteners are dry (solvent cleaned)
add 33% to as received condition torque. Bolt head identification marks indicate grade and may vary from manufacturer to
manufacturer. Thick nuts must be used on grade 8 capscrews. Use value in [ ] if using prevailing torque nuts

Fasteners
Before operating your Brillion machine, check all
hardware for tightness. (See "General Torque
Specifications" on page 4-1.)
After a few hours of use, check entire machine and
tighten any loose nuts or bolts. Daily or periodic checks
should be made thereafter.
When replacing bolts, be sure to use fasteners of equal
grade.
