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.

Upper Bearing and Race

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.

Support housing on housing flange

Remove the O-Rings and clean the upper and lower bearing housings.

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. 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.

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.

Apply a small bead of silicone to the seal flange circumference
