E-cowlboy Crankshaft Seal Remover & Installer Set for Ford 6.7L Powerstroke (2011–2022) — Front & Rear CNC Steel, OEM Fit

E-cowlboy Front and Rear Crankshaft Seal Remover & Installer Tool Set is a complete CNC-machined kit designed to remove and install front and rear crankshaft seals on Ford 6.7L Powerstroke Super Duty and compatible models without damaging the seal or housing.

This tool set contains purpose-built adapters and drivers engineered to fit Ford 6.7L Powerstroke diesel engines found in F-250 through F-750 trucks (model years 2011–2022 where specified), Low Cab Forward, E-Series and Excursion applications. Machined from heavy-duty steel with black anodizing, the parts reproduce OEM dimensions so technicians and DIYers can control installation depth, avoid seal distortion and prevent leaks. Note: the front adapter ring is for 2011–2019 BC3Z-6700-A seals only and must not be used on 2020+ LC3Z-6700-A seals.

How does this kit protect seals during removal and installation?

The set includes dedicated remover and installer pieces that center on the crankshaft and transfer force evenly, reducing gouging, bending or misalignment. Using the correct adapter for your model ensures the lip and seating surface are not nicked, which preserves the seal’s integrity and reduces the chance of oil leaks after service.

• CNC-machined steel parts for consistent fit and pressure distribution
• Front and rear-specific tools to avoid using makeshift punches
• Installer drivers that set the seal to exact OEM depth

Which vehicles and model years does this tool set fit?

This kit is built for Ford 6.7L Powerstroke diesel Super Duty trucks and selected commercial models. It covers F-250, F-350, F-450, F-550 for 2011–2021 and F-650/F-750 for 2016–2022, plus compatible Low Cab Forward, E-Series and Excursion platforms. Always verify the crank seal part number before using the front adapter ring.

• Compatible with BC3Z-6700-A (2011–2019) — use front adapter ring
• Do not use adapter ring with LC3Z-6700-A (2020 and newer)
• Replaces OEM tools: ST-152, ST-137B, ST-148, ST-138 and corresponding 303-series parts

What materials and manufacturing standards were used?

Each piece is CNC machined from premium steel and finished with a black anodized coating to resist corrosion and impact damage. Precision machining and heat-treated hardness deliver repeatable performance under workshop torque, extending the tool life compared to cast or low-grade kits.

• High-precision CNC machining for repeatable OEM fit
• Black anodized finish for anti-corrosion and durability
• Heat-treated components to resist deformation under load

Will this kit replace factory service tools and which operations remain manual?

This set replaces the common OEM pullers and drivers listed for front and rear crank seals, enabling safe removal and accurate seating without specialized presses for most installers. Note that the kit will not remove the flywheel adapter plate—some disassembly and manual handling are still required to access the rear seal.

• Direct replacement for ST-152, ST-137B, ST-148, ST-138 tool functions
• Not intended to remove the flywheel adapter plate
• Designed for bench or in-vehicle use with standard shop tools

Who this is for: This E-cowlboy set is aimed at professional mechanics, fleet maintenance shops and experienced DIYers who service Ford 6.7L Powerstroke engines and want a reliable, long-lasting alternative to OEM tools. If you need precise seal removal and installation, reduced risk of housing or seal damage, and tool geometry that matches factory specifications, this kit provides the parts necessary to complete the job efficiently. Confirm your vehicle’s crank seal part number and model year before use to select the correct front adapter configuration.
