1.4 TORQUE REQUIREMENTS
Torque nut to 169 -203 Nm (dry), then add extra torque to
line up the slot with the hole in the shaft to install the cotter
pin.
NOTE: When maintenance becomes necessary or a fas-
tener has loosened, to determine proper torque
value, refer to Figure 1-2., Torque Chart.
1.5 LUBRICATION
Hydraulic Oil
NOTE: Hydraulic oils must have anti-wear qualities at least
to API Service Classification GL-3, and sufficient
chemical stability for mobile hydraulic system ser-
vice. JLG Industries recommends Mobilfluid 424
hydraulic oil, which has an SAE viscosity of 10W-30
and a viscosity index of 152. When temperatures
remain consistently below 20° F (-7° C), JLG recom-
mends the use of MobilDTE13M hydraulic oil.
NOTE: Aside from JLG recommendations, it is not advisable
to mix oils of different brands or types, as they may
not contain the same required additives or be of
comparable viscosities. If use of hydraulic oil other
than Mobilfluid 424 is desired, contact JLG Indus-
tries for proper recommendations.
