Removal/Fitting Wheel; Replacing Rollers - DAL-BO Rollomaximum XL Manual

Removal/fitting wheel

Before removing wheel, fully extend the machine to the working position
with rings resting on ground. Wheels can then be raised off the ground.
Remove wheel nuts. Remove wheel. Replace wheel, hand-tighten wheel nuts.
Lower wheels to ground. Tighten wheel nuts to 510 Nm.
Ensure wheel nuts and wheel surfaces are clean to prevent nuts loosening.

Replacing rollers

Repairs must be performed with the machine connected to a tractor, resting on
a level surface, with the weight supported by the transport wheels.
This requires lifting gear, which can lift at least 1200 kg, as otherwise it will
not be able to overcome the spring preloading of 630 kg along with half of the
axle's weight.
Assembly
Assembly is in the reverse order to dismantling.
Note that a preloaded spring may spring back and cause personal inju-
ries. Therefore be very careful when working with preloaded springs.
