Drive wheel mounting
If the unit is supplied with the drive wheel already mounted this chapter is not applicable.
For the reliable attachment of the drive wheel to the wheel shaft of the transmission during operation, the
dimensional conformity of wheel shaft and drive wheel connection as well as the use of the correct fixing
parts at the specified tightening torque is decisive.
Prior to mounting and initial operation of inflated wheels the required air
volume is to be filled into the wheel!
(See information of the wheel
manufacturer)
Carrying capacity and air pressure acting on the wheel are not allowed to
exceed the recommendations of the wheel manufacturer.
It is mandatory to observe the instructions as to limited carrying capacities
and maximum speeds! Damaged, worn or deformed drive wheels are not
allowed to be repaired or mounted!
Pay attention that mounting of the drive wheel and the appropriate wheel
nuts as well as spring washers are in compliance with DIN 74361! Tires with
other dimensions or rim offsets require a written approval by ZF!
The centering and selection of the corresponding fixing elements for the drive wheel is made as follows:
•
for Vulkollan drive wheels over the centering collar of the wheel shaft with flat collar nut and spring
washer.
•
for pneumatic/CSE-drive wheels with spherical collar nut.
•
The drive wheel of the respective design and the appropriate fixing elements have to be fastened
with screws.
Prior to drive wheel mounting pay attention that the wheel shaft, the rim
mounting face, the wheel bolts, the spring washers and the wheel nuts are
clean, free from grease and undamaged.
Tightening torque for all fixing elements of the thread size M14x1.5 is 140 Nm.
