Install the bearingless TSC union [2]. Use the (4) socket-head cap screws (SHCS) [3]. Torque the SHCS. Refer to the Haas Fastener Torque Specifications document. Use the value for steel.

 Note: Turn the union [2] so that the hoses face to the left. This prevents damage to the motor shroud.

Connect the high-pressure braided hose [4] to the bearingless TSC union.

Connect the pressure-supply tube [5] to the push-lock connector on the bearingless TSC union regulator.

 Note: The push-lock connectors have colored cable ties that are the same color as the hose they receive.

Connect the vacuum-drain hose [6] to the bearingless TSC union. Use a hose clamp [7] to hold the hose.

Connect the vacuum-drain tube [8] to the bearingless TSC union.

Remove and discard the plug [1] from the TSC hose.

Remove the check-valve bracket [2] and the (2) socket-head cap screws [3]. The screws are on the other side of the cover. Attach the 90 degree fitting [5] to the bottom of the check-valve.

Attach the check-valve to the check-valve bracket. Use the (2) 1/4-20 x 1-1/4" socket-head cap screws (SHCS) [4].

Attach the check-valve assembly [6] to the rear spindle-head cover. Use the (2) 10-32" SHCS [7].

Connect the TSC hose [1] to the check-valve assembly.

Connect the pressure-sensor cable [2] to the check-valve assembly.

Connect the high-pressure braided hose [3] to the check-valve assembly [3]. The hose [3] is in the service kit.

 Note: If the hose [3] is too short, use the 90 degree fitting (P/N 58-3618) and the 45 degree fitting (P/N 58-3613). Disconnect the hose [3] from the bearingless TSC union. Connect the (2) fittings on top of the bearingless TSC union. Connect the hose [3] to the fitting assembly.

Connect the 1/4" tube [4] for the TSC purge solenoid to the check-valve assembly. The tube [4] is purple.

Connect the air-purge tube [5] to the check-valve assembly. This is the tube [5] that was disconnected from the reducer fitting. The tube [5] is black.

If the dome plugs [1] are near the front of the spindle:

Remove the dome plugs [1] from the bottom cover for the spindle. This is where you attach the vacuum generator.

Connect the vacuum-drain hose [2] to the vacuum generator. Use a hose clamp [3].

Connect the vacuum-generator tube [4] to the vacuum generator.

Move the vacuum generator [5] down into the space between the spindle cover.

Attach the vacuum generator [5] to the spindle-head cover. Use a 1/4-20 x 1/2" flanged button-head cap screw (FBHCS) [6].

If the dome plugs [1] are near the rear of the spindle:

Remove the dome plugs [1] from the bottom spindle-head cover. This is where you install the vacuum generator.

Remove the bottom spindle-head cover [2].

Install the vacuum generator [5] on the bottom spindle-head cover [2]. Use a 1/4-20 x 1/2" FBHCS [7].

Connect the vacuum-drain hose [3] to the vacuum generator [5]. Use a hose clamp [6].

Connect the vacuum-generator tube [4] to the vacuum generator [5].

Install the bottom spindle-head cover [2].

Install the assembly for the TSC-vacuum solenoid [1] in the upper manifold port. The assembly has a gray-cable tie.

Install the assembly for the TSC-purge solenoid [2]. The assembly [2] has purple cable ties.

Find the tube cap on the 1/4" gray tube [3]. Remove and discard the cap.

Trim the tube [3] to the correct length. Connect the tube [3] to the air regulator.

 Caution: Always trim tube ends at a 90-degree angle. This prevents a bad connection. If you cut the tube end at an angle, the tube does not make a good connection. A bad connection causes insufficient air pressure. Insufficient air pressure causes a malfunction.

Remove and discard the cap from the 1/4" TSC purple tube [4]. Trim the tube [4] to the correct length. Connect the tube [4] to the left fitting on the solenoid [2].

Remove the cover from the power supply (PSUP) PCB. Remove the electrical jumper at CB5 on the PSUP card. Remove the (3) push-on connector covers from position CB5.

Install the circuit breaker [1] at CB5.

Install the cover for the PSUP board. Make sure all breakers are in the ON position.

Connect the gray cable for the vacuum solenoid [2] to the correct connector panel. The connector panel is to the left of the air manifold.

Connect the purple cable for the purge solenoid to the correct connector panel. The connector panel is to the left of the air manifold.

 Caution: Make sure the color on the cable is the same as the color on the label. The decal on the connector panel has a color code and the connection name.

Find the cable [1] for the vacuum sensor.

Find the 4-pin connector [3] on the cable [1].

Find P26 [2] on the I/O PCB.

Connect the 4-pin connector [3] to P26 [2].

Connect the other end [5] of the cable to the vacuum sensor [4].

Push [RESET].

Push [AUX CLNT] to activate the TSC.

Inspect the TSC hoses for leaks.

Correct operation is as follows:

1. Coolant [1] flows correctly from the spindle.
2. A few drops flow from the vacuum-generator hose [3].

Push [RESET].

Put a TSC toolholder [2] in the spindle.

Push [AUX CLNT] to start the TSC.

Correct operation is as follows:

1. Coolant flows correctly from the spindle [1].
2. A few drops flow from the vacuum-generator hose [3].

Examine the TSC hoses for leaks.

Push [RESET].
