PTC-5013 Coupling (OEM: KOMATSU 561-01-12711) is a heavy-duty transmission coupling used in Komatsu machinery drivelines, designed for dump trucks and haul trucks. It connects the transmission output shaft to the driveshaft assembly, transferring rotational power while accommodating minor shaft misalignment. It is compatible with Komatsu HD785-2 / BH85 dump trucks.
Manufactured from high-grade alloy steel, the PTC-5013 coupling is precision-machined and heat-treated to withstand continuous high-torque loading and shock conditions typical of off-highway mining and earthmoving operations. Each unit is dimensionally matched to OEM specifications, ensuring direct drop-in fitment with no equipment modification required, and a full quality inspection report is available on request.
