6.3.11 REPLACING WHEELS
Before replacing one of the wheels, park the tractor on a horizontal and rigid surface, turn off the
engine and remove the key from the ignition. Secure the machine against movement. Do not replace
the wheel if the machine is not sufficiently secured in the elevated position!
If you do not have suitable tools or the necessary knowledge, contact your seller.
Perform the replacement as follows:
Place the jack underneath the front or rear bumper near to the wheel
which you wish to replace. For model AC 92-23 4x4 – always place the jack
against the frame - do not lean it on the transmission, this could damage it!
Keep lifting the machine until the wheel, which you wish to change no
longer touches the ground.
Remove the protective cover from the wheel.
Using a suitable screwdriver remove the retaining ring and remove the
washer.
Pull the wheel off the shaft.
When reattaching the wheel proceed in the reverse sequence to its removal. Before attaching the
wheel clean all parts and lightly grease the shaft with a plastic lubricant. Especially for wheels on the
rear axle this lubrication is essential for the subsequent removal of the wheel. In the event
that lubrication is not performed the subsequent attachment may be very difficult.
When attaching the rear wheel pay attention to the mutual alignment of the pin on the shaft and the
groove on the wheel.
Finally check the tyre pressure.
6.3.12 REPAIRING A TYRE PUNCTURE
The machine is equipped with tubeless tyres. In the event of a puncture have it repaired at a specialised
tyre repair shop or at an authorised Seco machine service centre.
