Worcester Hinge Assembly Lh 87186866190

Worcester LH Hinge Assy

The Worcester Hinge Assembly LH (Part No. 87186866190) is a genuine OEM (Original Equipment Manufacturer) replacement component designed for the external casing of Worcester Bosch Greenstar boilers. This Left-Hand (LH) hinge is the companion to the right-hand version, working together to support the drop-down decorative flap or control panel cover. As a genuine Worcester part, it ensures that the front fascia remains perfectly aligned with the boiler's main chassis for a professional, flush finish.

Key Features and Specifications
Left-Hand Orientation: Specifically engineered for the left-hand side of the boiler's lower control cover.

Structural Integrity: Made from high-quality, heat-stabilized plastic to prevent warping or snapping during regular use.

Flush Alignment: Designed to hold the front panel securely in place, preventing it from drooping or rattling when the boiler is operational.

Genuine Worcester Bosch Part: Guarantees a color-matched finish and exact mechanical compatibility with the Greenstar casing.

Service Accessibility: Allows the front flap to pivot open smoothly to a fixed angle, providing easy access to user controls and the system pressure gauge.

Boiler Compatibility
This hinge is a common spare part for the modern "i" and "Si" series of Greenstar boilers. Compatible models include:

Greenstar i (Combi & System): 25i, 30i.

Greenstar Si Compact: 25Si Compact, 30Si Compact.

Greenstar i (ERP Models): Post-2015 "i" models with the modern control interface.

Greenstar 2000 & 4000 Series: Certain specific revisions.

Technical Tip: These hinges are designed to be the "weak point" to protect the more expensive main casing. If the front panel is accidentally struck or forced, the hinge will usually snap first. If your front panel is sitting crooked or falls off when opened, replacing both the LH and RH hinges at the same time is recommended to ensure even tension and operation.

Installation Advice
Replacing the LH hinge is a straightforward task. However, care should be taken to support the weight of the front flap while the broken hinge is being swapped out to avoid snapping the remaining hinge or the plastic mounting tabs on the flap itself. No specialized tools are usually required, as these often feature a "push-and-click" or simple screw-retained mechanism.
