Bearings
The WC1208 chipper has six bearings. Figure 13 shows the bearings on the output shaft going
to the large pulley. Figure 14 shows the feed roller bearing. There is one on each side of the
feed roller carriage. The shield may need to be removed to access this bearing. All sealed bear-
ings should be greased lightly every 20 hours of use. Be sure to wipe all the dirt off of the tting
before greasing.

Figures 15 & 16 show the rotor shaft bearings. These should also be greased lightly every 20
hours. When greasing a sealed bearing, be careful that you do not over-grease or the grease will
push the rubber seal away and expose the bearing to dirt and moisture.
Shields have been removed to show detail. All shields must be on at all times during operation.
