Overview – HINGE A055X774 Series
A055X774 is the CUMMINS part number for this HINGE, fitted in generator set enclosure and access door applications. We keep the series in our catalogue and can quote it with or without related parts.
Parts Characteristics
A055X774 is the CUMMINS hinge used on generator set enclosure and access doors, built to the original leaf size and pin diameter for a direct replacement. The steel is treated against corrosion for outdoor enclosure service, and the pin is fitted for smooth door movement over the full opening range. The mounting hole spacing matches the original door frame, so the hinge swaps without re-drilling.
Applicable Models & Applications
This hinge is used on CUMMINS generator set enclosures and access doors where the original A055X774 layout applies, including weatherproof housings and service panels. Confirm the hole spacing and the leaf size against the hinge removed from your door before ordering. The related A055X777 covers the other common size in the series, and we can confirm the correct hinge from your enclosure model.
Maintenance & Replacement
Check the hinge pins and the mounting screws at each enclosure service, and tighten any loose screws before the door loading distorts the frame. Lubricate the pin lightly to keep the door moving smoothly and to prevent corrosion between the leaves. Replace the hinge when the leaves bind or the pin shows wear, and fit both hinges of a door as a pair to keep the alignment even.
Price Reference (USD)
Expect to pay roughly USD 50 – 150 for HINGE (A055X774). Bulk orders and repeat customers receive better rates; final pricing is confirmed by our sales team together with stock availability.
Value & Service
We match A055X774 against the original CUMMINS leaf and pin dimensions before dispatch, so the door lines up without adjustment. The hinge is held in stock together with A055X777, and both sizes can ship in one tracked order. As a corrosion-prone item on outdoor sets, we recommend replacing worn hinges in pairs during enclosure service.
