Starting motor for Komatsu D1301
This starting motor for Komatsu D1301 is supplied as a cost-effective alternative to the genuine part, manufactured to OEM dimensional specification. It drops into the existing mounting position and works with the original hardware.
Part number / cross reference
OEM and interchange reference: D1301-3708100
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
A failing starting motor announces itself with heat, noise and slow cycle times — by then the pump has already been eating itself. Replacing it early is far cheaper than a full hydraulic rebuild. This unit is built to OEM flow and pressure specification for the Komatsu D1301 and tested before dispatch.
Ordering, packing and warranty
Order quantity is flexible — one piece for a machine that is down, or a full container for your stock. Goods are packed part by part with clear labelling for your stores, and we provide inspection photos plus measured dimensions before the balance payment. Manufacturing-defect warranty 6–12 months.
