PREVENTATIVE MAINTENANCE
Stoelting recommends following this preventative maintenance schedule to keep the freezer clean and operating
properly.
WEEKLY
CLEAN INSIDE OF FREEZER
Remove all side panels and clean the inside of the freezer. Wipe any custard that may have dripped onto
the inner panels with a damp soapy towel. Wash the drain tray.
CLEAN REAR SHAFT SUPPORT BUSHING
Remove the rear support bushing by unscrewing it. Remove the o-ring and examine it. Replace the o-ring
if it is cracked or worn. Wash the bushing and lubricate the o-ring with Petrol-Gel.
CHECK FOR SHAFT ALIGNMENT
It is important to keep the auger shaft aligned at all times. There are a few early indications that the shaft
is out of alignment. Make sure there are no metal shavings under the bearing. Inspect the rear coupling
for wear. Check the front door plate for wear from the front bushing. If the shaft is out of alignment, the
freezer may be making a lot of noise.
Contact Stoelting Customer Service for an alignment kit if you suspect that the auger shaft is out of
alignment.
QUARTERLY
REPLACE BARREL PARTS
Follow the Parts Replacement Schedule to keep the freezer operating properly.
CLEAN CONDENSER COILS (AND FILTERS IF APPLICABLE)
The coils on the hopper, dipping cabinet and remote condenser need to be cleaned to ensure proper
airflow. Use compressed air to clean the condensers. Blow the air in the opposite direction of the normal
airflow. If the condenser has a filter, remove it and vacuum or brush clean. Rinse the filter with clean
water and allow it to dry before replacing it on the condenser.
ANNUALLY
REPLACE BARREL PARTS ACCORDING TO REPLACEMENT SCHEDULE
Follow the Parts Replacement Schedule to keep the freezer operating properly.
DRIVE BELT WEAR AND TENSION
Inspect the drive belts for wear. Check for wear marks from the belts rubbing on the pulley.
Press firmly on the belts. When tension is properly adjusted, the belt will depress the approximate width
of the belt with the pressure of a finger. If an adjustment is necessary, loosen the bolts holding the motor
to the frame and push the motor downward. Use a 5' long 2x4 as a lever to get the proper tension, and
then tighten the bolts.
LUBRICATE BEARINGS AND MOTORS
The pillow block bearings and the motors have grease fittings. Use a grease gun with Shell Alvania RL2,
Texaco Multifak 2, or equivalent as lubrication. Add enough grease on the bearings so that a small
amount appears on the drive shaft. The motor requires a small amount of grease. Apply one compression
of the grease gun to the grease fitting on the motor. Wipe all fittings clean after lubricating.
