1.12. To install the wheel, lift it onto the hub. It will
rest on the center boss of the mounting flange.
The valve stem must face out.
1.13. Rotate the wheel to align the holes in the wheel
with the holes in the mounting flange.
1.14. Insert one lug bolt through the wheel into the
mounting flange, and thread it into the mounting
flange finger tight.
1.15. Install the remaining four lug bolts.
1.16. Set the parking brake.
1.17. Lower the Big Country to the ground.
1.18. Tighten the lug bolts to a torque of 75 ft-lb.
NOTE: The tightness of the drive wheels should
be checked after 2 hours of operation, and again
after 10 hours of operation following wheel
removal.
2. Chain Lubrication
NOTE: The chains are relatively large (#60) for
this application, making them quite durable. The
design of the Big Country makes it well suited to
use in conditions that require the traction advan-
tages of four-wheel-drive. These conditions are
often dirty and abrasive.
NOTE: Traditional chain lubricants are made to
cling to the links. Chain lubricants also attract
and retain particulate matter when used in an
abrasive environment. This grit will act as grind-
ing compound as it circulates, wearing the
chains, chain guides, and sprockets.
• In abrasive environments, dry graphite or PTFE-
based lubricants are best.
• If operating conditions merit conventional chain
lubricant, use a lubricant specifically manufac-
tured for chains. Follow the lubricant manufac-
turers application instructions.
• Other lubricants such as motor oil or automatic
transmission fluid will be thrown off of the chain.
If thrown chain lubricant reaches the drive belt,
the belt will slip.
3. Chain Retention
If the chain retention is an issue:
3.1. Check chain tension: Adjust the tension on the
chain according to the instructions given in
“Chain Tension Adjustment”.
NOTE: If these procedures will not bring chain
tension into the specified range, the chain, chain
guides, and sprockets may be worn beyond ser-
viceable limits.
3.2. Make a visual inspection of the guides and
sprockets will determine if they are worn.
3.3. Remove the chain as described in the “Chain
Removal and Replacement” section of this man-
ual.
3.4. Measure the arc of the chain to determine the
amount of wear that has occurred. Place the
chain on a clean flat surface and bow it laterally.
See Figure 3.4.
NOTE: The chain is considered worn-out when,
with the half-link removed (49 links) the distance
between the outermost points of the end links is
less than 63”.
3.5. On units equipped with roller-type chain tension-
ers, the chain is considered worn-out if the half-
link has been removed but the tensioners have
insufficient travel to maintain tension on the
chain.
