iFJF 7835 Rear Main Oil Seal Remover & Installer Kit — Ford 7.3L Powerstroke
When your 1998–2003 Ford 7.3L Powerstroke develops a rear main seal leak, you need the right tool for the job — not a makeshift setup that risks damaging the crankshaft or the new seal. The iFJF 7835 Rear Main Oil Seal Remover and Installer Kit gives you OEM-grade tooling at a fraction of the dealer cost. Whether you're a professional diesel mechanic or a dedicated DIY owner keeping your 7.3L on the road, this kit makes rear main seal replacement precise, efficient, and frustration-free.
Key Features & Benefits
Complete Remover & Installer Set
Unlike single-function tools that only remove or only install, the iFJF 7835 kit handles both sides of the job. The precision-machined remover extracts the old seal without gouging the crankshaft surface, while the installer presses the new seal to the exact factory depth — no guesswork, no leaks.
Heavy-Duty Steel Construction
Built from thick-gauge steel that won't flex or deform under torque. The tool surfaces are machined flat and true for consistent seal alignment during installation. This isn't stamped sheet metal — it's a professional-grade tool designed for repeated use in commercial shops.
Precision Fit for 7.3L Powerstroke (1998-2003)
Engineered specifically for the Ford 7.3L Powerstroke diesel engine found in 1998–2003 F-250, F-350, F-450, and F-550 Super Duty trucks, as well as 2000–2003 Excursions and E-Series vans. The tool dimensions match the factory seal specifications exactly.

-
Removal: Position the remover tool over the old seal and tighten evenly to extract the seal without tilting or binding.
-
Surface Inspection: Inspect the crankshaft sealing surface for scoring or damage. Polish lightly if needed.

Frequently Asked Questions
Does this kit work on the 1994-1997 7.3L Powerstroke?
This kit is specifically designed for the 1998–2003 7.3L Powerstroke. The 1994–1997 (OBS) 7.3L uses a different rear main seal design and requires a different tool set. Please verify your model year before ordering.
Can I use this tool without removing the transmission?
No. The rear main seal is located between the engine block and the transmission bellhousing. The transmission (and flywheel/flexplate on automatic trucks) must be removed for access. This is an advanced job — only undertake it if you have the proper equipment and experience.
What type of seal should I use with this tool?
The iFJF 7835 kit is compatible with all standard replacement rear main seals for the 1998–2003 Ford 7.3L Powerstroke, including OEM Ford (F4TZ-6701-A) and aftermarket equivalents. Always use a new seal — never attempt to reuse a removed seal.
Can this tool be used on other engines?
This kit is engineered specifically for the 7.3L Powerstroke. While it may physically fit some other applications, we recommend using the correct tool for your specific engine to ensure proper seal depth and alignment.
