1.5 TORQUE REQUIREMENTS
NOTE: See Procedure Section for tightening sequence of
turntable bearing bolts.
NOTE: When maintenance becomes necessary or a fas-
tener has loosened, refer to the Torque Chart to
determine proper torque value.
1.6 LUBRICATION
Deutz F4L912 Engine
Single Viscosity Oils (CD-SE, CD-SF)
Multi-Viscosity Oils (CD-SE, CD-SF)
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 index of
152.
NOTE: When temperatures remain consistently below 20
degrees F (-7 degrees C.), JLG Industries recom-
mends the use of Mobil DTE13.
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.
When Outside Temp is Consistently
Use SAE Viscosity
