P/N 185009 is a DEK belt drive motor assembly based on the Dunkermotoren BG40X25 motor. The documented motor rating is 24VDC, 1.3A and 16.2W, and the assembly is also found with a PLG42S gearhead. Matching should start from the complete DEK part number, motor label and installed belt-drive position rather than from the BG40X25 motor model alone.
If the driven belt starts intermittently, hesitates, runs unevenly or fails to move, the motor is only one possible fault point. First inspect the belt path, pulley and mechanical resistance, then check the motor loom, connectors and power/control side before treating the 185009 assembly as the confirmed failure.
A wrong motor or gearhead configuration can change the available drive speed and torque at the belt mechanism, which may show up as unstable transport, repeated motion faults or inconsistent belt movement. Because DEK uses several different motors for camera, print-carriage, rail and belt functions, do not select a replacement only from motor size or connector appearance.
If the exact belt-drive position is unclear, send the motor label, installation-area photos and a short fault video. Remote technical support is available to help narrow the problem toward the belt/pulley mechanism, motor loom, drive motor or control side before replacement. Other DEK motor references can be checked in the SMT Motor range.

For matching and quotation, send the complete 185009 motor label, exact DEK printer model, photos of the installed position, motor and connectors, the fault description or short video, and required quantity. We can first help check the likely fault area and confirm the motor, gearhead and installation match before issuing the formal quotation.
Common versions are normally kept in stock, and confirmed orders can usually be arranged for shipment within 24–48 hours. Urgent line-repair requests can be prioritized where applicable. A formal specification confirmation sheet and OEM-reference comparison can also be provided for purchasing records and approval.
After-sales support and warranty are available, with the exact terms confirmed for the specific order. Exchange-repair support can also be checked for eligible repairable units.
