Electric Ball Machine Troubleshooting & Replacement Parts Instructions

The balls feed slowly.

Blockage - As you dump balls into the hopper, debris can fall into and block or slow the passage of balls to the front of the machine. Empty all balls from the ball machine and lift it forward until any debris drops out.

The balls get jammed in the rotor.

Elbow Off Center - Sometimes the elbow can become off-center, preventing balls from dropping properly and causing them to become jammed in the rotor. Gentle pressure should be enough to move the elbow back into place. If this doesn't work, try tapping the elbow on the outside to dislodge a potentially stuck trap door.

No velocity when balls exit the machine.

Detent - The detent is a rubber bladder inside the metal sleeve shot tube that regulates the ball machine's air pressure. Replace your detent if the ball ejects with reduced speed or if it frequently becomes trapped. You should also consider replacing the Detent if you need to replace your Rotor [further down on page] and/or Rotor Spring [further down on page].

• I want to read how to do this in the manual before buying a new detent.
• I need to replace my Detent.

The ball feed isn't working properly.

Back Leg - Confirm that the back leg sits flat on the ground. If it's become bent, it will disrupt the ball feed and should be replaced.

• I need to replace my back leg.

The chain broke at the nub.

Cam Assembly - If the chain has broken off at the nub, you must replace your entire cam assembly. This part is only applicable to the Tournament Model (model 401).

• I want to read how to do this in the manual before buying a new cam assembly.
• I need to replace my Tournament Model 401 Cam Assembly.

The chain broke in the middle.

Chain Extender - If the chain breaks in the middle, purchase a chain extender. This part is only applicable to the Tournament Model (model 401).

• I want to read how to do this in the manual before buying a new channel.
• I need to replace my chain extender.

The height angle keeps changing.

Channel - If your machine is no longer maintaining the height you selected, your channel may be worn out. This part is only applicable to the Tournament Model (model 401).

• I want to read how to do this in the manual before buying a new channel.
• I need to replace my channel.

The rotor isn't turning.

Rotor - The rotor is a four-hole carousel in the hopper. A screw holds the rotor to the shaft of the motor. If loose, try retightening the rotor screw. You may identify the attachment screw by looking through the hole in the back of the hopper. Replace the rotor if it is cracked and consider replacing the detent [detent earlier on this page] at the same time.

• I want to read how to do this in the manual before buying a rotor.
• I need to replace my Rotor.

The balls are jamming in the hopper.

Rotor Spring - The Rotor Spring is designed to keep balls from jamming in the hopper. If it breaks or bends, replace the spring and consider replacing the detent [detent earlier on this page].

• I want to read how to do this in the manual before buying a rotor spring.
• I need to replace my 301/401 Model Rotor Spring.
• I need to replace my 201 Model Rotor Spring.
