Overview – General Parts WINDOW 4665021 Series
Built to Hitachi specifications, the WINDOW 4665021 serves Hitachi EX1900-6 mining excavator operator cab glazing; the cross-referenced series below covers the most common substitutions.
Parts Characteristics
A tempered glass cab window panel supplied with its rubber gasket frame, made for the EX1900-6 operator cab. The glass is heat-treated so it breaks into blunt granules rather than shards, and the gasket both cushions the glass against machine vibration and keeps the dust and rain out of the pressurised cab.
Applicable Models & Applications
Fits the Hitachi EX1900-6 excavator operator cab in the corresponding window position. Confirm which glazing position you need – front, door, rear or roof lights differ in curvature and cut-out – by your parts book page or a photo of the broken panel.
Maintenance & Replacement
Clean cab glass with water and a soft cloth first, lifting grit off the surface before any wiping. Dry-sweeping a dust-loaded window drags particles across the glass and cuts the visibility exactly where the operator needs it most, around the working face.
Replace a chipped or cracked panel at the next service window, not eventually. A tempered panel with an edge chip can fail without warning – commonly during vibration from travel – and a cab with taped-over broken glazing loses its pressurisation and dust control entirely.
When fitting a new panel, work the gasket evenly around the glass and the frame opening with no twists, and seat the locking strip fully. Check that the panel sits square in the aperture before final locking – a twisted fit stresses the glass edge, which is where tempered panels are weakest.
Inspect gaskets annually for hardening and shrinkage, especially on machines parked in strong sun. A shrunken gasket lets dust past into the cab and lets the panel rumble in its frame; replacing the gasket at the first sign of gaps preserves both the glass and the cab air-conditioning.
Price Reference (USD)
For planning purposes, allocate USD 200 to USD 500 per WINDOW 4665021, excluding local import duties.
