Injector Sleeve for Caterpillar 3114, 3116 and 3126 Engines

Product Specifications

Technical Overview: This injector sleeve is a precision-machined component designed to seal the fuel injector within the cylinder head of Caterpillar 3114, 3116 and 3126 diesel engines. The injector sleeve provides correct injector alignment and prevents coolant leakage into the combustion chamber under operating temperature and pressure.

Component Description:
• Product type: Injector sleeve / injector tube
• Installation location: Cylinder head
• Function: Injector sealing and positioning
• Required quantity: 6 sleeves per engine (6-cylinder configuration)
• Material: Copper, designed for controlled mechanical deformation sealing

Engine Compatibility:
This injector sleeve is designed for Caterpillar medium-duty diesel engines equipped with two valves per cylinder, including:
• Caterpillar 3114
• Caterpillar 3116
• Caterpillar 3126 (mechanical / MUI versions)

Installation Notes:
Installation of this injector sleeve for Caterpillar 3116 engines requires a dedicated expansion and cutting tool. Proper installation ensures the sleeve is securely seated and prevents coolant migration into the combustion chamber during engine operation.
