APOLLO 2472560017 Analog Leveling Sensor Legacy Replacement for Asphalt Paver Grade Control System

Buyers searching for this part number are rarely shopping for technology. They are holding a paver that was specified with analog grade control, and they need the sensing link restored long enough to finish the season. Replacing an analog sensor with a modern digital system means new controllers, new harnesses, new calibration routines and a crew that has to learn them — a project disguised as a spare part.

The APOLLO 2472560017 is offered as that missing link: a direct analog sensing element that talks to the existing control system through a plain cable harness, with zeroing done mechanically by the operator rather than through a service laptop. It is a maintenance decision, priced and documented as one.

1. Park on level ground and lower the screed. Isolate the machine electrically before touching the harness.
2. Unplug the old sensor, note the cable routing, then remove the two mounting fasteners and lift the unit clear of the ski or tow-point bracket.
3. Fit the replacement with the same fastener pattern, reconnect the harness and check the pivot moves freely through its full travel.
4. Zero the linkage mechanically, then pave a short test strip and trim the sensitivity dial until the correction matches the mix and base condition.

Send a photo of the sensor currently fitted, the machine model and the part number stamped on the body. We check the connector family, the probe length and the bracket pattern against the original specification before dispatch, so the part that arrives is the part that fits.
