How-To Guide :: Frozen Beverage :: Replacing Belts

Spaceman Frozen Beverage machines utilize motors to drive a pulley which turns a belt attached to a gearbox. The belts need to be replaced on a regular basis when they begin to show signs of wear.  Spaceman recommends replacing these belts once per year.  This article will go over the steps to replace the belts on your Frozen Beverage machine.  For information on replacing pulleys, please see the FB: Replacing Pulleys article.

Parts Ordering: The replacement belts can be purchased via Parts Town.  Please refer to the parts list for your machine to determine the correct belt(s) for your model.  


Required Tools

  1. Flathead screwdriver
  2. Metric hex driver or allen key set
  3. Metric or Adjustable Wrench set
  4. Insulated Needle Nose Pliers
  5. Clamp-style Amp Meter

How to replace Motor Belts:

  1. Turn Power Switch to Off and unplug the machine from the wall.
  2. Follow the instructions in the Operator Manual to properly drain, disassemble, and clean the machine.  

Warning: The machine must be unplugged as power may be available to certain components even with the machine power switch in the off position.

  1. Using a flathead screwdriver, unlock all panel locks remove the rear and side panels from the machine.  All panel locks are quarter-turn and should turn inward to unlock, they do NOT require significant force to unlock. For floor-standing machines, generally only the top panels need to be removed.  

Note: For smaller countertop machines, panels may be installed using an 8mm Hex-head bolt rather than quarter-turn panel locks.

  1.  Using needle nose pliers to pinch the tensioning post on the motor bracket, and an adjustable wrench or socket, loosen the tension on both motor mount springs to loosen the belt tension.
  2. Remove the belt from the pulleys and set aside.
  3. Verify the pulleys and bushings on the motor and the gearbox to ensure they are tight and inline.  If they are not inline, please see the FB: Replacing Pulleys article for information on adjusting pulleys.
  4. Install the new belt on the pulleys.  If the belt is too tight, loosen the spring tensioning bolts further until the belt easily installs on the pulley.  Ensure the belt is vertically aligned and make pulley adjustments, as necessary. 
  5. Check belt tension.  There should be approximately +/- 0.5 inches of play in the belt.  
  6. Using needle nose pliers to hold the motor tensioning shaft and an appropriate wrench or socket, tighten the motor mounting springs until the belt tension is set correctly. 

Warning:  Do NOT over-tighten belts.  This may cause overheating and damage to the motor or gearbox.

  1. You should be able to turn the belts by hand freely without binding or noise.  To test the motor functionality, plug the machine back into power.  Place a clamp meter around one of the black power wires, and press in the contactor that drives the motor.  The motor should turn on and read approximately 1.0 Amps or less for 220V machines, and approximately 4.0 Amps for 110V machines with no load.  If the amp-draw is too high, loosen the belt tension slightly.  Unplug machine from the wall before continuing.
  2. Reinstall electrical box covers, and side panels. 
  3. Follow Operator Manual to Lubricate, Assemble, Sanitize, and add product to the machine.
