ATLV 4300 330495 (10--98)

FRONT AXLE

The front axle on the ATLV

t

4300 is a pivoting,

spring mounted design. The pivoting design

allows the machine to be driven over uneven

terrain and still have all four tires contact the

ground. The leaf spring provides a comfortable

ride.

TO REMOVE FRONT AXLE ASSEMBLY

1. Lower the vacuum head. Disconnect the

vacuum head from the axle assembly

FOR SAFETY: Before Leaving Or

Servicing Machine; Stop On Level

Surface, Set Parking Brake, turn off

machine, and remove key.

2. Removal of the front axle is easier with the

front tires removed.

3. Loosen the eight wheel nuts before lifting the

front end of the machine. DO NOT remove

the wheel nuts at this point.

4. Jack up the front of the machine at the

indicated jack points. Install jack stands

under the machine frame.

5. Finish removing the eight wheel nuts.

Remove the tire and wheel assemblies from

the machine.

6. Remove the three hex screws holding the

head lift actuator assembly to the left side of

the operator compartment. Let the actuator

assembly drop down and out of the way so

the pivot pin can be removed.

7. Mark, remove, and cap the two hydraulic

hoses leading to the steering cylinder on the

front of the axle assembly.

NOTE: Observe hydraulic cleanliness

requirements when opening hydraulic lines.

8. The front axle assembly must be supported

before any hardware is removed. Use jack

stands or a floor jack.
