This is a front crankshaft seal and wear sleeve installer. This tool is for use with the followinmg applications: 2008-2010 Ford F-250, F350, F450, F-550, 6.4L Ford Powerstroke engines, VT365-MaxxForce7, and navistar international. This is a replacement to part number ZTSE-4705, and 303-1260.The ATC ZTSE4705 Front Crankshaft Seal and Wear Sleeve Remover Tool is a professional-grade service fixture designed to remove the front crankshaft oil seal and wear sleeve on Ford 6.4 L PowerStroke, VT365/MaxxForce 7, and Navistar International diesel engines. Built as a direct replacement for OEM reference ZTSE-4705 / 303-1260, this tool allows technicians to extract the front seal cleanly and efficiently without damaging the crankshaft, sealing surfaces, or surrounding components — a critical step in front seal replacement and crank service.
In engines such as the 2008–2010 Ford F-250, F-350, F-450, F-550 with the 6.4 L PowerStroke, the front crankshaft seal is exposed to high heat, vibration, and oil pressure. Over time these factors can cause seal hardening, leakage, or improper wear sleeve fitment. Improvised removal methods often risk scoring the crankshaft journal or damaging the engine front cover. The ATC ZTSE4705 fits the crankshaft seal profile and wear sleeve design on these engines, providing controlled extraction and helping prepare the area for proper seal and wear sleeve replacement.
This tool is ideal for heavy-duty truck service departments, professional diesel repair facilities, and fleet maintenance operations where PowerStroke and VT365/MaxxForce engines are regularly serviced. It simplifies what can otherwise be a difficult job, improving efficiency and reducing the risk of secondary damage during front seal service.

Front crankshaft seal and wear sleeve removal during front seal service and engine rebuilds
Why It Matters
Front seal replacement on large-bore diesel engines is a common but critical service task. Improper removal can score the crankshaft or distort seal bores, leading to repeated leaks and costly repairs. Using the ATC ZTSE4705 tool ensures that worn or leaking seals are extracted cleanly, enabling technicians to install new seals and wear sleeves with confidence and restore proper engine sealing integrity.
