AXLE FORK LIFT METHOD

This is an alternative method for towing the vehicle, but requires standard 5" forks, (see

Figures 6-2 and 6-3) and designated lift points inside the axle clamp groups. The follow-

ing procedure must be used:

■

Place a spacer on the boom, to provide adequate clearance between the oil pan and

the boom if necessary. Lift the vehicle in order to place spacer under tires. This will pro-

vide sufficient room under the axle to locate forks in the proper position.

■

Install the fork in the boom properly.

■

Position the tow forks directly under the axle, inside the axle clamp groups as shown

in Figure 6-2.

PROPER TOW FORK LOCATION ON INSIDE CLAMP GROUP ON THE STEERTEK AXLE

■

Prior to lifting the vehicle, ensure that the bottom axle plate is flat in the tow fork to

minimize any gap between the bottom axle plate and the tow fork, see Figure 6-4 and

6-5. It may be necessary to deflate the air in the steer axle suspension, and/or release

the tractor brakes. Deflate the steer axle air springs by disconnecting the height control

valve linkage and lowering the height control valve linkage arm. This will exhaust the

air pressure in the steer axle air springs.

NOTE When lifting a vehicle with an under lift boom, care must be taken not to damage the

engine’s oil pan. Vehicles equipped with a front fairing may require removal of the front

fairing prior to towing to prevent component damage.

■

Lift vehicle and secure the vehicle to the boom.

■

Install safety straps, it is preferred to use nylon safety straps. Chains have a tendency

to bind and may cause damage to the axle.
