DIESEL PARTS / INJECTORS AND INJECTOR SERVICE PARTS

# Injector Holders and Nozzle Assemblies

Find injector holders and nozzle assemblies for mechanical diesel injectors. Holder and nozzle details must match the original configuration.

Send the complete injector number, engine model and any identification marks. We can help you explore parts options and discuss testing or service for supported injectors.

## Injector design and application

Holders carry the nozzle and other mechanical injector components. Body and nozzle variants must match the original assembly.

## Identify the correct Injector Holders and Nozzle Assemblies

Send holder and nozzle markings, overall assembly photos and the engine model.

For an injector inquiry, distinguish the complete assembly from a nozzle, holder or service part. Supply any manufacturer marks and the engine identification to reduce the risk of ordering the wrong design.

## Testing, Service and Replacement Options

Determine whether the customer needs a complete assembly, a specific holder or an approved inspection service.

Cleaning alone does not verify injection performance. Testing, rebuild suitability, return-flow or electrical checks depend on injector design. Ask which procedures are appropriate for the specific supported injector.

## Injector Holders and Nozzle Assemblies: numbers and identification

You may also find these parts listed as diesel injector holder, nozzle holder assemblies, mechanical injector holders. Injector design, complete part number and application determine the correct match.

## Ask DCT about Injector Holders and Nozzle Assemblies

Include the injector or nozzle number, engine identification, relevant cylinder observations and any completed injector testing. DCT can confirm current sourcing options for the correctly identified part; only published store listings establish checkout availability.
