Hydraulic Fitting Installation (SAE Straight Thread O- Ring Fitting into Component Port)
Non- Adjustable Fitting (Fig. 7)
1. Make sure all threads and sealing surfaces of fitting
and component port are free of burrs, nicks, scratches
or any foreign material.
2. As a preventative measure against leakage, it is rec-
ommended that the O- ring be replaced any time the
connection is opened.
3. Lightly lubricate the O- ring with clean hydraulic oil.
Fittingthreads shouldbeclean withnolubricant applied.
IMPORTANT: Before installing fitting into port, de-
termine port material. If fittingistobeinstalledinto
an aluminum port, installation torque is reduced.
4. Install the fitting into the port. Then, use a torque
wrench and socket to tighten the fitting to the recom-
mended inst allation torque shown in Figure 8.
NOTE: Useofanoffsetwrench(e.g.crowfootwrench)
will affect torque wrench calibration due to the effective
length change of the torque wrench. Tightening torque
when using a torque wrench with an offset wrench will
be less than the recommended installation torque. See
UsingaTorqueWrenchwithanOffsetWrenchinthe
Torque Specifications section of Chapter 2 - Product
Records and Maintenance todetermine necessarycon-
version information.
5. If a torque wrench is not available, or if space at the
port prevents useof a torquewrench, analternate meth-
od of assembly is the Flats From Finger Tight (F.F.F.T.)
method.
A. Install the fitting into the port and t ighten it down
full length until finger tight.
B. If port material is steel, tighten the fitting to the
listed F.F.F.T. If port material is aluminum, tighten f it-
ting to 60% of listed F.F.F.T.
