Tool
A special tool is needed to replace the wheel bearing: 506 37 61-02.
Parts of the tool kit are used both for removal and installation of the drive
wheel bearing.
It is important that the tool's sliding surfaces – threads, washers – are lubri-
cated in order for the tool to function optimally.
Dismantling

Remove the cutting blade as per Chapter 4, "Replacing the blade". Leave the
drive wheel in place.
Water disc
Remove the four screws that hold the water disc. Remove the screw to the
water connection nipple (black arrow).
Remove the nipple from the disc. Check the O-ring on the connection that
forms a seal with the water disc, it can come loose during removal.
Transmission housing
Unscrew the four screws securing the cover and remove it.
During reinstallation: Check that the cover's seal, above the tensioner wheel,
is correctly positioned in the groove.
Drive belt

Belt pulley
Lock the rotation of the pulley by pressing in the rotation stop lug under the
pulley. Remove the centre screw and remove the pulley.
If the pulley cannot be removed by hand – knock the shaft down a little
using a brass drift until the pulley comes loose. Never pry the pulley using a
tool as this will damaged it.
