Check
Check that the axle and the bearing
seating in the cutting arm are not
damaged. If the bearing is seriously
damaged so that it has been scored, in all
probability the axle or cutting arm must
be replaced due to the damage a seized
bearing causes to the bearing seating or
the axle.
Check
Check that the axle and the
bearing seating in the cut ting
arm are not damaged.
Prepare bearing replacement
The bearing housing must be secured so
that the bearing can be fitted vertically.
The bearing housing must be accessible
both from the upper and the underside.
Using a vice to hold it works well.
Use soft jaws to prevent damage to the
bearing housing.
