The Honda 91551-Z15-000 Control Case Collar is a genuine OEM component designed for a wide range of Honda generators, including the EB3800, EB5000, EB6500, EG4000, EG5000, EG6500, EM3800, EM5000, EM6500, and EP2500. As a direct Honda OEM part, it is manufactured to the same standards. Confirm your unit's serial number against the fitment table before ordering, as Honda supersedes parts at serial breaks and this collar may not apply to every production run of each model.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this collar matches the original specification for correct engagement within the control case assembly.
- Broad Generator Compatibility — listed for Honda EB, EG, EM, and EP series generators including the EB3800, EB5000, EB6500, EG4000, EG5000, EG6500, EM3800, EM5000, EM6500, and EP2500.
- Serial Number Verification Recommended — Honda updates part numbers across production runs; check your generator's serial number against the fitment table to confirm this is the correct collar for your unit.
- Structural Integrity of the Control Case — a worn or damaged collar can allow movement or misalignment within the control case, affecting the stability of the controls it houses.
A control case collar is a positional or retaining component used to locate and secure elements within the generator's control case housing. It maintains the correct alignment and spacing of the parts seated around or through it, keeping the control assembly properly positioned during operation. When this collar is worn, cracked, or missing, components within the control case can shift out of position, leading to imprecise control operation or accelerated wear on surrounding parts.
