Starting motor for D7D
This starting motor is a direct replacement part developed for D7D. It is built to OEM dimensional specification, so it installs in the original position without any modification to the surrounding assembly.
Part number / cross reference
OEM and interchange reference: EC250D | EC240 | EC290 | D7E | D6E | EC140
Use the number from your parts book to confirm interchangeability. If your number is not listed, send it to us — we cross-check against the parts manual and confirm in writing before you pay, because a wrong part costs far more in freight and downtime than the part itself.

Fitment can change on a serial-number break within the same model. Send us the model and serial number from the machine nameplate and we verify it against the parts manual before dispatch.
Why this part fails — and what we do differently
Hydraulic parts fail from contamination and heat far more often than from load. This starting motor is assembled on a clean bench, run on the test rig at rated working pressure plus safety margin, and shipped with every port sealed. Confirm displacement, rotation and port thread against the D7D before ordering — that is where most wrong orders happen.
Ordering, packing and warranty
Single pieces ship for urgent breakdowns; consolidated container or air freight is available for stock orders. Each part is packed individually in a carton with the part number labelled, and we send photographs of the actual goods plus a measurement report before shipment. Warranty: 6–12 months against manufacturing defect under normal operating conditions.
