Put a 6" x 6" x 6" (152 mm x 152 mm x 152 mm) wood or aluminum block [3] on the table.

Put the spindle on the block.

Make sure that the spindle lubrication port [1] is in the front.

Put a long 5/16"-18 screw [4] through the rear hole on the motor adapter. This screw helps you align the motor adapter to the spindle.

Put an indicator against the spindle coupler [1]. Zero the indicator.

Slowly turn the spindle with your hand to find the highest point on the coupler.

Put a mark on the point with a permanent marker.

Examine the coupler on the motor [2].

If the motor coupler has a mark, proceed to step 3.

If the motor coupler does not have a mark:

• Put an indicator against the motor coupler [2]. Zero the indicator.
• Slowly turn the motor by hand to find the highest point.
• Use a permanent marker to mark the point.

Apply grease to the transfer tube at these locations:

• the o-ring [1] at the top
• the socket [2] for the o-ring on the draw bar.

Push the transfer tube [4] onto the top of the draw bar [5].

Install the spider coupler [3].

Remove the tape [1] from the spindle lubrication port.

Apply a small quantity of grease to the spindle seal o-ring [2].

Insert the o-ring into the lubrication port [3].

Put the tape over the lubrication port of the spindle that was removed.

Slowly jog the Z Axis in the negative (-) direction until the head mount [1] is 0.5" (13 mm) above the spindle flange [2].

Use your hand to slowly turn the spindle coupler [5] until the mark on the spindle coupler aligns with the mark [4] on the motor coupler [3]. Align the (2) marks as closely as possible.

Slowly jog the Z Axis in the negative (-) direction.

 Caution: Lower the lift as you jog the Z Axis. The motor must be supported by the lift until the spindle is connected to the motor adapter.

Make sure the spindle is centered in the spindle bore.

Make sure the couplers engage smoothly.

Remove the temporary screw you used in step 1.

Install (4) motor mount screws [1] into the motor mount adapter [2].

Torque the screws. Refer to Haas Fastener Torque Specifications.

Remove the motor support lift.

Attach the oil supply fitting.

Connect the oil supply tube.

Place the indicator touching the spindle shaft [1]. Rotate the shaft until the coupling's high spot faces out.

Jog spindle head to measure the Y-axis offset between the two couplings.

Then, rotate spindle shaft CCW 90 degrees until the coupling's high spots faces out.  

Jog spindle head to measure the X-axis offset between the two couplings.

Torque the screws. Refer to HAAS FASTENER TORQUE SPECIFICATIONS.

 NOTE: If coupling offsets exceed tolerance, break all 4 upper motor mount screws loose and tap the motor into place until offset is within tolerance. 

Put (4) screws [1] into the upper inside bearing block of the rocker assembly.

Put (4) screws [9] into the outer bearing block.

Put the rocker assembly [3] onto the spindle casting. Use the lower bearing block [2] on the inside as a guide.

Use a dowel pin [8] to align the outside bearing block.

Put the rocker arm [7] through the yoke [5] on shaft from the air cylinder.

Push the clevis pin [4] through the arm and the yoke.

Put the C-clip [6] onto the clevis pin.

Torque all of the screws. Refer to the Haas Fastener Torque Specifications.
