DO NOT LUBRICATE BOLTS OR FINAL DRIVE
HUB THREADS. Wheel bolts should be turned in at
least three full turns by hand
before using power
tools to prevent thread damage. Use a Torque
Multiplier (6) and Torque Wrench (8) to tighten bolts.
New Delivered Machine - Wheels Installed
Torque wheel bolts after 10 hours of operation. Use a
Torque Multiplier (6) and Torque Wrench (8) capable
of delivering at least 980Nm (725 foot pounds).
IMPORTANT: The wheels and wheel hardware
“seat” relative to each other during the first 10 hours
of operation. This retorquing procedure is critical to
the structural integrity of the wheels and wheel bolts.
New Delivered Machine - Wheels Not Installed or
When Changing Wheels
Install wheels and hardware per the Installation
diagrams shown on Next Page. Torque wheel bolts to
270 Nm (200 foot pounds), mark bolt head relative to
wheel. Tighten each bolt an additional 90 degrees.
Drive the Combine to a large firm level surface and
perform 10 “Figure 8’s”. Retorque all bolts to 980 Nm
(725 foot pounds). Retorque again after 10 hours of
operation.
IMPORTANT: Final drives use a special locking (not
straight) thread design. DO NOT use a standard M22
tap to repair threads damaged during installation. To
repair damaged threads - use a M22 locking thread
tap available from your dealer.
