Komatsu Engine Mount - Part 195-54-78412

The 195-54-78412 engine mount is designed for Komatsu large bulldozers including the D155, D275, and D375 models. This heavy-duty rubber mount supports the diesel engine and absorbs torsional vibrations generated during high-load dozing operations. The mount must withstand significant dynamic loads as the machine encounters varying ground conditions. HAMM Mount manufactures the 195-54-78412 using a reinforced NR compound with steel reinforcement plates, ensuring dimensional stability under continuous heavy loading in mining and earthmoving applications.

Manufactured by HAMM Mount in our ISO 9001:2015 certified facility using advanced vulcanization technology and premium rubber compounds. Every unit undergoes multi-stage quality control including dimensional inspection, hardness verification, and load-deflection testing. Fire safety compliance per EN 45545-2 is verified for all railway applications.
