Bearings, Water Seal and O-Rings
There is a bearing at the top and bottom of the auger shaft to allow the auger to rotate freely
with a minimum amount of friction. The lower bearing is a sealed ball bearing and the upper
bearing is a tapered roller bearing.
Tap the upper race out of the bearing housing.
The bearings can be inspected once removed from the machine
by turning the bearing by hand. If the bearing does not turn
smoothly, it should be replaced. Visually check the tapered
roller bearing, if it is pitted, corroded or shows signs of wear, it
must be replaced.
To remove the upper bearing race from the upper housing, turn
the housing over and carefully tap the race out of the housing
using a punch and hammer.
To remove the lower bearing and water seal, turn over and
support the housing assembly by the flange on the housing,
carefully tap on the bearing with a punch and hammer until the
water seal and bearing are removed from the housing.

Upper Bearing and Race
Support housing on housing flange
Remove the O-Rings and clean the upper and lower bearing
housings.
Housings Shown Inverted
Install the new upper bearing race and lower bearing in their
respective housings with a bearing press or a bearing driver. Do
not use a hammer directly in the bearing or bearing race.
Bearing Install new O-Rings in the upper and lower housings; lightly
lubricate the O-Rings with white food grade grease. Lubricate the
upper bearing and bearing race
Install the lower water seal in the bearing housing by first applying
a thin bead of silicone around the water seal flange
circumference. This will prevent water from leaking between the
housing and metal portion of the seal.
Upper O-Ring
I.D. of pipe to match O.D
of water seal flange
Press the water seal into the housing with a bearing press and a
short piece of PVC pipe.
Place the pipe over the seal so that the pipe is in contact with the
flange portion of the seal. Use a 2-3/4 I.D. pipe for 3 inch seals
and a 1-3/4 I.D. pipe for the 2-1/2 inch seals. Insure that the pipe is
cut off square. Use extreme caution to prevent damage to the
seal. Remove any excess silicone from the flange.
