Coupling

Suited to scheduled maintenance, repair and component renewal, the Coupling (OEM 3115 1684 00) serves an important function in the lubrication and service-fluid circuit. Its role is to transmit, locate or support rotary motion so the connected mechanism can operate smoothly under variable drilling loads.

Cross-reference data lists applications including BOLTEC 235 and BOLTEC LC; final fit should be confirmed against the machine configuration or serial information. As an aftermarket alternative, it supports practical spare-parts planning and helps reduce dependence on a single supply channel. Accurate mating dimensions support stable engagement and help reduce unwanted play, edge loading or vibration in the rotating assembly.
