The Harvey G1960 Gear Box Assembly is a genuine OEM replacement for the internal drive housing of H25-series twin tank softeners. This assembly acts as the central hub for the system's mechanical "brain," protecting the gearing and providing the pressurized connection points required for accurate water metering.
📦 What’s Included:
-
G1960 Gear Box Top Casing: The high-durability housing for the internal gears.
-
O-Rings: Premium-grade seals for both the upper and lower interface points, ensuring a leak-free installation.
Key Symptom: Why Replace the G1960?
The most common reason for replacing the Gear Box Assembly is a leak at the threaded port connection.
-
Thread Fatigue: Over years of vibration and pressure cycles, the threaded ports on the gear box can develop hairline cracks or become cross-threaded during a service.
-
Persistent Weeping: If you have replaced the O-rings but water continues to seep from the connection between the gear box and the manifold, the housing itself may be warped or damaged.
-
Internal Gear Misalignment: If the gear box casing is cracked or compromised, the internal gears (G0921-G0892) may not mesh correctly, leading to a failure in the regeneration trigger.
