Removal
1. Tag and disconnect the hydraulic lines to the cylinder.
Cap or plug all lines and openings.
2. Remove the cotter pin, washer, and the retaining nut
from each end of the cylinder.
3. Remove the cylinder.
Installation
1. Install the cylinder in position and secure it with the
attaching nut and washers. Torque the nut 140 to 170
Nm (103 to 125 lb-ft). Tighten the nut to the nearest
cotter pin hole and install the cotter pin. Add additional
washers as necessary to ensure proper seating of cotter
pin in nut.
2. Connect the hoses as per removal tags.
WHEELS AND TIRES
Description
One size of tires is available for the front axle: 445/65R22.5.
NOTE: The tire diameters, widths, and weights may vary
slightly depending on the tire manufacturer.
Tires are designed to operate with a certain sidewall
deflection or bulge. Correct air pressure ensures proper
deflection which ensure proper traction, flotation, support of
load, and prevents excessive flexing of the tire. Over inflation
increases rim stresses, which results in lower rim life.
Refer to and adhere to the inflation pressures on the Tire
inflation decal on the crane.
Maintenance
Assemblies
NOTE: Do not lubricate the wheel studs or lug nuts. With
aluminum wheels, lubricate the wheel pilot or hub
pads only with a synthetic lubricant containing
Teflon. Do not lubricate wheel or axle faces.
1. Position the wheel assembly on the mounting studs.
Install the lug nuts and tighten them until they are just
snug, rotating the wheel so the nut being tightened is in
the top position.
2. Ensure the wheel assembly is positioned properly on the
hub. Tighten the lug nuts in the sequence shown to a
preliminary torque of 37 Nm (50 lb-ft).
3. Torque the lug nuts 610 to 678 Nm (450 to 500 lb-ft) in
the sequence shown in (Figure 8-11).
4. Maintain proper torque on wheel lugs and check for
proper wheel mounting. Retorque the lug nuts 80 to 160
km (50 to 100 mi) after the wheels are removed and
reinstalled. This will reseat the lug nuts. Check the
torque every 800 km (500 mi) thereafter. An alternative
to re-torquing after 80 km (50 mi) is to run the machine in
large figure 8’s six or seven times and then re-torque the
lug nuts.
REAR AXLE AND SUSPENSION
Rear Axle
The rear axles have single reduction differentials. The
differentials have hypoid drive pinions, ring gear sets, and
bevel gears. A straight roller bearing is mounted on the head
of the drive pinion and all other bearings are tapered roller
bearings. If equipped with a differential lock, the differential
CAUTION
Equipment Damage Hazard!
Do not mix tires or rims from different manufacturers.
WARNING
Do Not Dismount or Mount Tires Without Proper
Training!
The high pressures involved can cause tire, rim parts, and
tools to fly apart with enough explosive force to cause
severe injury or death to personnel and damage to crane
and surrounding area.
