The Honda 91551-Z23-000 Control Case Collar is a genuine OEM component designed for Honda EB4000, EB5000, EB6500, EM4000, EM5000, and EM6500 generators. As a direct Honda OEM part, it is manufactured to the exact specifications required for these generators, giving you a straight swap with no guesswork on fit or sizing. Confirm your generator's serial number against the fitment table before ordering, as Honda supersedes parts at serial breaks and this listing may cover specific production ranges.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this collar meets the original design specifications for the control case assembly on these generators.
- Broad Generator Fitment — listed for Honda EB4000, EB5000, EB6500, EM4000, EM5000, and EM6500 conventional generators; verify your serial number against the compatibility table to confirm the correct application.
- Direct-Fit Replacement — engineered to the original dimensions, this collar installs in place of the worn or damaged original without rework or modification to surrounding components.
The Control Case Collar is a precision-fit collar that locates and retains the control case on the generator, keeping the control assembly correctly positioned during operation. When this collar becomes worn, cracked, or damaged, the control case can shift or develop unwanted play, which may affect the stability and operation of the controls. Replacing it with a genuine Honda part restores the original fit and keeps the control assembly secure.
