Use a 5/16″ (8 mm) socket to remove the three screws holding the electronics and power supply to metal frame.

Move all wires clear of the electronics assembly to prevent tangling or damage to them while the assembly is removed.

The electronics assembly should now be free. Take it to a workbench for the next step.

Disconnect the power inverter from the drive board by pulling on the connectors.

CAUTION: Do not pull on the wires!

Use a 5/16″ (8 mm) socket to remove the two screws holding the power inverter to the electronics plate.

Set the power inverter and its mounting plate aside.

Position the mounting plate around the power inverter in the same manner as when removed.

Align the power inverter and mounting plate to the holes on the new electronics with the mounting plate flanges ON TOP OF the electronics plate. (The larger holes should be on top of the smaller holes for the screws to hold the assembly together)

Use a 5/16″ (8 mm) socket to attach the power inverter to the electronics using the mounting plate and the two screws previously removed.

Connect the power inverter to the drive board at the connection marked “110.”

NOTE: Only one orientation is possible.

NOTE: Connector colors on drive board may be different.

Set the new assembly in the machine where the old was removed and use a 5/16″ (8 mm) socket to install the three screws removed from step 21. Reconnect the ground wire with a screw that does not have an insulating washer.

CAUTION: Make sure all wires are free and do not get pinched!

Connect the wire harness to the drive board.

Use a small flat head screwdriver to start both screws in the housing into the drive board before tightening either. Tighten both screws in the connector.

Connect the six gray connectors to the PLC by pushing them into place. Ensure that they are fully seated before continuing.

NOTE: Each connector is keyed to fit a specific location.

Tuck wiring neatly to avoid pinching/cutting wires.

Connect the switch wire harness (4 wires) to the drive board at the location labeled “ON/OFF.”

NOTE: Only one orientation is possible.

Align the label on the machine top to the existing holes and use a #2 Phillips head screwdriver to replace the six screws.

NOTE: The bottom middle screw will be in a different location if the previous label did not have a switch. It can be pre-drilled with a #30 drill bit.

Orient the touchscreen with the power indicator on the left side and gently place the touchscreen in the machine opening. Keep a hand on it to prevent dropping.

Tilt the top back, and hook two mounting brackets in the rectangular slots on the bottom side of the touchscreen. Use a short #2 Phillips head screwdriver to tighten only enough so the brackets won’t fall out.
Do not tighten screws yet!

Keep a hand on the touchscreen to prevent it from falling out and tilt the top forward. From the back of the machine, install two brackets in the rectangular slots on the top side of the touchscreen. Use a long handle #2 Phillips head screwdriver to tighten the bracket lightly snug.
CAUTION! DO NOT OVERTIGHTEN MOUNTING SCREWS!

Move top into position.

From the front of the BG PXT,® gently pick up on the top with a hand on each side.

Holding the top just high enough for the skirt to clear the hose hanger, slide the top to the right, into approximate home position.

Tidy up plumbing/wiring. Take care to tuck all wires in neatly.

Align the top with the frame, being careful NOT to disconnect or pinch any wiring (as shown in photo) or hoses.

From the front of the BG PXT,® slide the left skirt of the plastic top barely onto the frame so that both corners engage the frame.

Slide a small flat blade screwdriver between the right skirt of the machine top and the frame until the top slides into position. The mounting holes in the plastic top should lineup with the holes in the metal frame top.

Fasten the machine top to the metal frame with a 5/16″ (8 mm) socket to replace the four screws.

Insert the F2 funnel into top and orient connector toward the tubing. Insert tubing in connector and push until it stops. There should be approximately 1/8″ (3mm) of engagement after soft stop is reached.

IMPORTANT! This connection needs to be checked for leaks. Add fluid into the funnel, if there are leaks, push the tubing in further until it is fully seated.

Replace the faceplate. Insert one corner of the faceplate into the top and slide it as far as it will go into the proper side.

Press the other corner into place. The bottom flange may need to be bumped to go into place.

Align the holes and use a 5/16″ (8 mm) socket to replace the screws.

Insert the F1 funnel into top.

Take care to properly insert the hose into the hole in T1.

CAUTION: If the hose is not properly installed, a large spill could occur!

Place the handle onto the P1/P2 ball valve and rotate the handle until it engages the valve.

Use a #2 Phillips head screwdriver to replace the screw.

Check fan operation. Power the BG PXT® and place your hand near the fan slots on the back right of the console top. You should feel air movement from the fan.

If there is no air movement, the fan wires may have been damaged and
need to be re-crimped.

To calibrate the scales, press the gear button on the home screen to go to the maintenance screen.

On the maintenance screen, press the scale button on the top right.

On the scale screen, press both T1 and T2 buttons along the bottom. They should light up green.

Press the home button on the bottom left.

From the main screen, press T1. Follow the instructions to empty T1 new fluid container. Let the function run completely and stop itself.

NOTE: This function will run longer than usual as it is self-calibrating.

From the main screen, press T2. Follow the instructions to empty T2 used fluid container. Let the function run completely and stop itself.

NOTE: This function will run longer than usual as it is self-calibrating.

Follow the instructions in steps 74–75 for calibrating the scales.

Both scales should read between –0.5 and –0.7 QT/L and the T1 and T2 lights should be gray (not green).

If one or both are still green, perform the corresponding empty function again and let it run until it shuts itself off.

To test the scale calibration, press the gear button on the home screen to go to the maintenance screen.

On the maintenance screen, press the diagnostic button.

Enter password “2652686”.

On the diagnostic screen, check the values of both scales. “NZ” and “UZ” should each be in the range of 150 to 350.

If NZ is outside this range, stop and replace the LEFT scale.*

If UZ is outside this range, stop and replace the RIGHT scale.*

*Order Scale/Signal Conditioner for PXT, PN PXT-012. New scale must be recalibrated.

Add exactly 16 QT of transmission fluid to T1 new fluid container through F1 funnel.

IMPORTANT! Use an accurate external measurement tool for proper calibration test! Markings on the T1 new fluid container are not precise.

Follow the instructions in steps 74–75 to view current scale readings. The calibration procedure should have emptied the tanks to –0.6. Adding exactly 16 QT of transmission fluid should make the T1 read between 14.9–15.9 QT. If the scale is outside this range, stop and replace the LEFT scale. Order Scale/Signal Conditioner for PXT, PN PXT-012. New scale must be calibrated.

Remove the drawer hose from T2 used fluid container.

Connect a small open-ended adaptor to H1 service hose (marked hose) and insert it in the T2 used fluid container hole for the drawer hose.

From the home screen, press T1 and follow the instructions to transfer the fluid from T1 new fluid container to T2 used fluid container.

CAUTION: Hold the hose in place to prevent it from falling out!

Remove adaptor and store H1 service hose.

Replace the drawer hose into T2 to the same depth it was originally.

Move the drawer in and out several times to make sure the hose moves freely and does not move T2.

Close and latch the drawer.

Follow the instructions in steps 74–75 to view current scale readings.

T2 should read between 14.9 –15.9 QT if the scale is good.

If this scale is outside this range, replace the RIGHT scale. Order Scale/Signal Conditioner for PXT, PN PXT-012. New scale must be recalibrated.

Use PVC cement to glue the H1/H2 plastic label to the left of the service hose connections.

Slide the heat shrink onto H1 service hose and use a heat torch to form the heat shrink around the service hose connection.
