How to replace these motor from the HAAS CNC machines?

1. Safety Precautions

Always power off the machine and disconnect energy sources before starting. Wear safety gloves and goggles.

2. Tools & Materials Needed

Putty knife

Acetone & clean cloth

Dielectric grease

Torque wrench (refer to HAAS Fastener Torque Specs)

Replacement servo motor & coupler access gasket

3. Removing the Servo Motor

Step 1: Clear Access to the Motor

Power Down: Turn off the machine completely.

Remove Obstructions:

Axis Component to Remove Location

Y-Axis Back column enclosure Rear of the machine

X-Axis Saddle’s left waycover Left side of the saddle

Step 2: Expose the Coupler

Peel back the coupler access gasket [1] using a putty knife if stuck.

Step 3: Disconnect the Motor

Loosen the lower coupler clamping bolt [1].

Disconnect the power cable, noting its orientation.

Remove the motor mounting bolts [2].

Pull the motor straight out to disengage it from the ballscrew.

Step 4: Remove the Coupler

Loosen the upper coupler clamping bolt [3] and detach the coupler.

4. Installing the New Servo Motor

Step 1: Prepare the Coupler & Shaft

Key Alignment: Ensure the shaft key is installed on the ballscrew ([1]).

Hand-rotate the new motor shaft to match the old motor’s orientation.

Step 2: Attach the Coupler

Slide the coupler onto the ballscrew ([2]).

Note: Keep clamping bolts loose temporarily.

Step 3: Mount the Motor

Align the motor shaft key ([3]) with the coupler’s keyway.

Push the motor into the housing and secure with mounting bolts [4].

Torque bolts to HAAS specifications.

Step 4: Secure the Coupler

Center the coupler ([5]) between the motor and ballscrew.

Torque both clamping bolts [5] to spec.

Step 5: Reapply the Gasket

Clean the housing surface with acetone.

Apply a new coupler access gasket [6].

5. Critical Installation Tips

Dielectric Grease: Apply sparingly only to connector contact points.

Cable Connections:

Power Cable: Align the amphenol key slot and twist to secure.

Encoder Cable: Match arrows, push until locked, then gently tug to confirm.

Home Sensor: Align and twist to secure.
