Torque values listed are for general use only, based on the strength of
the bolt or screw. DO NOT use these values if a different torque value or
tightening procedure is given for a specific application. For stainless steel
fasteners or for nuts on U-bolts, see the tightening instructions for the
specific application. Tighten plastic insert or crimped steel type lock nuts
by turning the nut to the dry torque shown in the chart, unless different
instructions are given for the specific application.
Shear bolts are designed to fail under predetermined loads. Always
replace shear bolts with identical property class. Replace fasteners with
the same or higher property class. If higher property class fasteners are
used, tighten these to the strength of the original. Make sure fastener
threads are clean and that you properly start thread engagement. When
possible, lubricate plain or zinc plated fasteners other than lock nuts,
wheel bolts or wheel nuts, unless different instructions are given for the
specific application.
a
“Lubricated” means coated with a lubricant such as engine oil, fasteners with phosphate and oil coatings, or M20
and larger fasteners with JDM F13C, F13F or F13J zinc flake coating.
b
“Dry” means plain or zinc plated without any lubrication, or M6 to M18 fasteners with JDM F13B, F13E or F13H zinc flake coating.
Service Intervals
CAUTION: Before making any adjustments or
doing any service work, always:
- Switch the machine off
- Remove the key from the ignition
- Wait until all the moving parts have
come to a standstill.
IMPORTANT: The intervals quoted here are for
average conditions. Adverse operating
conditions may make it necessary to apply
lubrication more often.
IMPORTANT: Replace any damaged parts.
Any screws that have worked loose must be
retightened to the proper torque.
Clean grease fittings before lubrication. Replace lost or
damaged grease fittings immediately. If a new fitting fails
to take grease, remove it and check whether the grease
passage is blocked.
Perform lubrication and maintenance work mentioned in
this section before and after every harvesting season as
well.
