4W7022 Nozzle A for Caterpillar Equipment

4W7022 Nozzle A is a fuel injection system component used with Caterpillar equipment. The listed application is the Caterpillar 3406B engine, including truck engine and industrial engine configurations. This is a new aftermarket spare part manufactured by CTP (Costex Tractor Parts).

The part is identified as a nozzle for the fuel injection system. The available fitment information specifies the 3406B engine series and does not provide additional machine model designations. Application should be checked against the engine configuration and the part number installed on the equipment before use.

Fitment

• Caterpillar 3406B truck engine
• Caterpillar 3406B industrial engine

The fitment information identifies the engine series rather than a complete list of truck, machine, or industrial equipment models. The component is therefore described for Caterpillar 3406B applications only, based on the available product data.

Cross-reference numbers

• 4W7022
• 4W-7022

4W7022 and 4W-7022 are the number formats provided for the same nozzle identification. The hyphenated and non-hyphenated formats are included for part-number reference when comparing catalog records and equipment documentation.

Specifications

The dimensional and weight values above are reproduced from the available product data. The source lists both inch and metric measurements without identifying whether they refer to the component itself, its packaging, or separate measurement points. For this reason, the values are shown as provided and are not recalculated or interpreted as converted equivalents.

Before installation, compare the removed nozzle with the 4W7022 / 4W-7022 identification and verify the Caterpillar 3406B engine application. The available data does not specify nozzle material, thread details, spray pattern, installation position, adjustment requirements, or additional items included with the part.
