The Puller Screw supports the safe removal and installation of cylinder heads on engines that use smaller diameter fuel injection nozzle adapters by allowing controlled force application during the process. It helps technicians separate and seat cylinder heads without causing stress to surrounding components, reducing the chance of surface damage. By guiding aligned movement during removal and installation, the tool improves accuracy and workflow efficiency while supporting repeatable results during service tasks.Attributes:• Supports accurate installation of cylinder heads after service.• Maintains stable engagement with smaller diameter nozzle adapter openings.• Reduces risk of cylinder head misalignment during handling.Applications: The Puller Screw is used within the engine service area during cylinder head removal and installation procedures, and allows controlled force application when working around fuel injection nozzle adapter openings.
