Stop risking cylinder head damage on your DD5. The ATC W93658900700 is the precision-engineered 2-jaw expanding tool designed for the safe removal and installation of carbon-seized injector cups.

Precision Sealing for the Detroit DD5 Platform

The Detroit Diesel DD5 engine relies on a perfect seal at the injector cup to isolate fuel delivery from the cooling system. When these cups (sleeves) become carbon-bound or corroded, removal becomes a high-stakes operation. Using the wrong puller can lead to gouged head bores and catastrophic coolant leaks.

• Superior 2-Jaw Design – Unlike 4-tooth aftermarket versions that can slip, the ATC 2-part expanding jaw provides a massive internal grip surface for seized cups.
• Dual Functionality – A complete solution for both extraction and precision installation, ensuring the new cup is seated to the exact OEM depth.
• Cylinder Head Protection – Distributes extraction force evenly to prevent distortion of the head bore or the injector sleeve itself.
• Corrosion & Carbon Mastery – Engineered to handle sleeves that have been "welded" into the head by thousands of heat cycles.
• Shop-Grade Durability — Heavy-duty, precision-machined construction built for the daily demands of fleet maintenance and diesel repair shops.
