How To Replace The Pit Electronics In A Walthers N Scale 130' Turntable

When my first generation N Scale Walthers 130' turntable failed, one solution was to replace the  Pit Electronics in the pit of the old turntable. I wasn't able to do this because the opening under the bench work wasn't large enough when I first installed the turntable on the layout. If you buy a new Walthers N scale 130' DCC turntable, make sure the opening under the bench work is at least nine inches square, which will give you plenty of room to remove the pit electronics of the Walthers N scale 130' turntable. Usually the electronics in the pit doesn't fail but it can happen.

In my case I had to remove the turntable from the bench work, lifted all 24 stall tracks and 12 holding tracks which allowed me to remove the old turntable from the layout. I had to purchase a new Walthers DCC 130' turntable because Walthers no longer supplied the electronics from the first generation Walthers 130' turntable. However the electronics in the pit of both turntables are the same.

Below are the instructions that the Walthers chief technician in the Turntable Department sent me if I wanted to remove the electronics from the old turntable pit.

Replacing the Pit Electronics

Turn the new pit upside down and loosen the four screws at the center of the pit.

Make sure the plastic channel is free to move. The channel runs along the bottom of the pit and holds the wires that connect to the sensor.

Turn the pit right side up and push the sensor housing out of the wall in the pit.

Turn the pit upside down and remove the round plastic housing that holds the fingers.

Be careful not to pull the wires off of the sensor or fingers when handling the sensor.

When installing the new electronics in the old pit, hold the round plastic housing in place and tighten the screws half way.

Insert the plastic channel under the round housing. Make sure it can move freely.

Next, push the sensor housing into the opening in the wall of the pit. There’s a ledge on the front of the sensor housing. Sometimes it is a tight fit so take your time.

After reinserting the new sensor make sure the housing is flush with the inside wall and the bottom of the pit.

Tighten the screws.

Thats all there is folks.
