86386216 Casing for Montabert HC50 Hydraulic Drifter

The 86386216 Casing is the integral main hydraulic valve housing for Montabert HC50 heavy-duty hydraulic drifter. As the core outer shell of the drifter’s percussion and rotary valve system, it integrates dozens of precision hydraulic oil passages, central piston mounting bore, multi-position bolt fixing holes and threaded oil inlet/outlet ports. It serves as the base carrier for all internal valve core, piston, seal and distribution components, forming the complete hydraulic control chamber of the HC50 rock drill.

Manufactured strictly to Montabert OEM drawing standards with high-strength cast alloy aluminum blank + precision CNC finishing, this casing achieves full direct interchangeability with original factory spare parts. In harsh underground mine, tunnel and quarry working environments with high hydraulic pressure, continuous high-frequency percussion vibration, abrasive rock dust and corrosive mine water, it maintains stable sealed hydraulic circulation, eliminates internal oil cross-leakage, avoids valve system failure and greatly cuts unexpected breakdown downtime of your Montabert HC50 drilling equipment.
