1.2 TORQUE REQUIREMENTS
Self locking fasteners, such as nylon insert and thread
deforming locknuts, are not intended to be reinstalled
after removal. Always use new replacement hardware
when installing locking fasteners..
NOTE: Anytime a wheel bolt is replaced, be sure one of the
same length is used. Use bolt shown below on wheels
that use the 1/4" (6.4mm) ring.
NOTE: After tightening the spindle nut to the proper torque,
loosen completely until you can turn by hand. Finger
tighten nut by hand without rotating hub. Install cot-
ter pin by backing nut off, if necessary, in order to line
up slot.
When maintenance becomes necessary or a fastener
has loosened, refer to Section 1.8, Torque ChartS to
determine proper torque value.
1.3 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 DTE 11M hydraulic
oil.
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 DTE 11M is desired, contact JLG Industries for
proper recommendations.
