Track width, axles and wheels

Altering the track width (optional combo axle)
The track width of the adjustable combo axle on the Navigator 3000/
4000 can be infinitely adjusted from 60" to 120". No adjustment is
necessary on the fixed 60" or fixed 120" axle.
1. Measure the current track width (center RH tire to center LH tire).
Each side must be extended or retracted half the desired
alteration.
2. Attach the sprayer to tractor and engage tractor parking brake.
3. Place stop wedges in front of, and behind RH wheel. Jack up LH
wheel, support and secure sprayer body.
4. Loosen the jam nuts and bolts (A) for LH wheel axle.
5. Extend or retract the axle. Never extend axle insert too far. Some
part of the axle insert must always be visible through sight hole (B).
6. Tighten the clamp bolts (A) to a torque of 290 Ft/lb (390 Nm) and
lock the bolts with the jam nuts.
7. Repeat the procedure on RH wheel.
8. Check if the distance from center of tire to center of rear frame is
equal at RH and LH. Make sure both axle inserts are visible through
sight hole (B). It may be necessary to change the wheel offset in
order to achieve desired distance (see instructions below).
9. Retighten bolts and wheel bolts to specified torque after 8 hours
of work.
See "50 hours service - Wheel bolts and nuts" in the "Maintenance" section for proper torque and tightening sequence of
wheel hubs to rims.
±
WARNING! Securely support the sprayer during axle adjustments. Never attempt to adjust axles with liquid in the tank.
Always block wheels on opposite side when adjusting axles.
±
WARNING! Place a jack under the axle and lift the wheel to remove load from the clamps before tightening the clamp
bolts to the specified torque.
±
WARNING! The front and rear axle inserts must always be visible through the sight hole (B), located in the front and
rear of the axle assembly. Otherwise, axle is extended too far to be safe and warranty will be voided.
˜
ATTENTION! Sight hole (B), located in the front and rear of the axle assembly, may be used as a quick reference for a
120" axle width. When the end of each axle insert is centered in the whole, the axle spacing will be 120" with proper
wheel offset.
Changing the wheel offset
1. To change the wheel offset, the LH and RH wheels must be swapped in order to turn the rim dish and keep the correct
tread direction (tread up in front).
2. Jack up the frame behind both wheels, support and secure sprayer body.
3. Remove both LH and RH wheels and swap sides (keeping the tread direction the same). Tighten wheel bolts to
specified torque.
See "50 hours service - Wheel bolts and nuts" in the "Maintenance" section for proper torque and tightening sequence of
wheel hubs to rims.
±
WARNING! Securely support the sprayer while swapping wheels. Never attempt to swap wheels with liquid in the
tank. Always secure the rear frame when swapping wheels.
