REPLACING DRIVE WHEEL BEARINGS
Assemble bearings
Perform the following operations with the machine horizontal.
The transmission side should be facing up and the underside should be
accessible.
Support washer
Parts of tool kit 506 37 61-02 are used for bearing assembly.
Note that the tool kit washer cannot be used as a support when the inner
bearing is assembled. The washer will come into contact the bearing before it
reaches the top of the chassis.
Use a pair of oversized standard washers as a support.
(The washer in the tool kit is intended for the assembly of main bearings on
cutting machines with combustion engines.)
Assemble inner bearing
Place the bearing on the support plate and hold it on the underside of the
bearing housing. Insert the screw through the washers on the top and fit the
screw in the support plate on the underside.
Lock the screw and rotate the nut until the bearing comes into contact with
the stop at the top.
Check assembly
Now check that the bearing is completely in contact with the chassis.
The bearing seat dictates the alignment of the drive wheel and pulley when
all components are installed.
Spacer ring
The spacer ring is to be situated between the first bearing and the one to be
installed now.
The spacer ring and wear ring are almost identical in size, but their
materials and machining are significantly different and the rings must not be
confused. Note that the spacer ring, the ring on the left, is now to be used in
the following operations.
Assemble outer bearing
Locate the bearing and the spacer ring on the support plate and hold it
under the bearing housing. Use the triangle in the tool kit for this and the
following operations.
Note the position of the triangle – the triangle directly supports the
assembled inner bearing.
Pull in the bearing using the tool until the spacer ring comes into contact
with the inner bearing.
