The Wacker Neuson is a genuine OEM Chain Guard Cover designed for the HSH hydronic surface heater family, including the HSH700G, HSH650, E2200, and E3000 ES Ground Heater series. As a factory-sourced component, this cover is manufactured to the exact tolerances and material specifications of the original part, ensuring a correct, tool-compatible installation with no modifications to the housing or mounting points. It fits across the full range of E2200 variants — including generator-equipped, lift bail, and 3 kW generator configurations — as well as the E700M and E3000 ES models. When your existing cover is cracked, missing, or damaged, replacing it promptly with part number keeps the chain drive properly guarded and the heater running as intended.
Key Features
- Genuine OEM Construction: — Molded or formed to original dimensional specs, ensuring the cover seats flush and secures correctly against the chain drive housing without gaps or misalignment.
- Direct Bolt-On Replacement: — Matches the original mounting pattern on HSH-series hydronic surface heaters for a straightforward swap using standard hand tools.
- Broad HSH Family Fitment: — Confirmed for HSH700G, HSH650, E2200 (all variants), E3000 ES Ground Heater, and E700M hydronic surface heaters.
- Chain Drive Protection: — Shields the internal chain drive mechanism from debris, moisture, and jobsite contamination that can accelerate wear and cause premature drivetrain failure.
- Operator Safety: — Enclosing rotating chain components is a critical safety requirement; a missing or damaged cover exposes personnel to moving parts during heater operation.
The chain guard cover on a hydronic surface heater encloses the drive chain that transfers power from the engine or motor to the pump or circulation system. By containing the chain within a protective housing, it prevents contact with external debris, water, and ice — all common on cold-weather ground-thawing worksites — that would otherwise accelerate chain stretch and sprocket wear. When the cover is cracked or absent, rotating components become an exposure hazard and the drive system is left unprotected against the harsh conditions these heaters are built to operate in.
