This is a replacement to part # ZTSE-4516, and 303-761
The ATC ZTSE4516 Front Crankshaft Seal & Wear Ring Installer is a precision-engineered heavy-duty service tool designed for professional diesel technicians to install the front crankshaft oil seal and wear ring on Ford PowerStroke® 6.0 L engines — replacing Ford OEM 303-761 / ZTSE-4516 with full coverage on common platforms.
Front crankshaft seals on the 6.0 L PowerStroke (2003–2010) are a critical sealing surface that sits at the interface between the crankshaft snout, harmonic balancer, and engine oil cavity. Incorrect installation — such as hammering or using generic tools — often leads to seal distortion, accelerated wear, and costly oil leaks that can require repeated service visits. The ATC ZTSE4516 is precision machined to set the front seal and wear ring straight and to the correct OEM depth, minimizing the risk of repeated leaks or damage to surrounding surfaces.
This installer tool is ruggedly constructed for repeated professional use in repair shops, fleet maintenance facilities, heavy-duty garages, and dealership service departments. By using a dedicated installer, technicians can improve service quality, reduce labor time, and protect valuable engine components during front crankshaft sealing procedures.
Key Features & Benefits
-
OEM Replacement Tool: Direct aftermarket equivalent to Ford 303-761 / ZTSE-4516 front seal and wear ring installer for 6.0 L PowerStroke.
-
Precision Machined: Built to install seals at factory-correct depth for optimal sealing and long-term reliability.
-
Professional-Grade Construction: Heavy-duty steel design built for repeated shop use without deformation.
-
Damage-Free Installation: Reduces the risk of seal lip damage, wear ring misalignment, and crankshaft surface scoring common with improvised installers.
-
Time & Cost Savings: Speeds up front crankshaft seal service and reduces the risk of return repairs due to improper installation.
Typical Applications
Ideal for front crankshaft seal and wear ring installation on Ford PowerStroke 6.0 L diesel engines, including:
-
Super Duty F-250, F-350, F-450, F-550, and F-650/750 applications (model years 2003–2007).
-
Ford E-Series (E-150, E-250, E-350, E-450) vans equipped with 6.0 L PowerStroke (2004–2010).
-
Ford Excursion 6.0 L (2003–2005).
By installing the wear ring and front crank seal correctly, this tool helps prevent oil leaks at the crankshaft snout — a common source of engine oil seepage on high-torque diesel engines.
