DRIVE CHAIN 3.3
Adjusting The Drive Chain
After checking the chain for proper free play, you may
need to make an adjustment.
1
Access the chain tightener located at the front of the
operators compartment, just above the foot rests, by
removing the cover shield. (fig. C2008)
IMPORTANT
Adjusting the chain tension
too loose will allow the
chain to “WHIP” and pos -
sibly cause part failure.

Torque nuts
5 Torque the 3 chain tightener nuts to 150 lbs/ft
(203nm) And recheck the chain tension. (fig. C2270)
6
Tighten the adjuster nut against the plate. Re-seal the
plugs and replace the inspection covers.
If proper chain tension adjustment can not be reached
using the adjuster plate the chain will need to be replaced.
Do not remove extra links from the chain. It has reached
it’s normal service life and must be replaced.
2 Loosen the 3 tightener nuts approximately 1/4 turn.
(fig. C2009) Do not loosen too much. This would allow
the chain tightener to drop too low and give a false read-
ing when the chain is check for tension.
3
Loosen the rear adjuster nut. (fig. C2009) Turn the
forward nut in to tighten, or out to loosen, the chain.
4
Inspect the chain adjustment again. It must be 1/4 to
3/8 inches (6 to 9mm) at 30 lbs pull (13.6kg).
7 Replenish the final drive housing with 7 liters 1.9
gal) of API classification SE / CD oil.
8
Install the wheels and torque the wheel nuts to specs
on page 3-2. (fig. C1658)
