Kent‑Moore J‑46911 Fuel Injector Seal Protector – DPF Injector Seal Installation Tool
The Kent‑Moore J‑46911 Fuel Injector Seal Protector is a factory‑approved GM service tool designed for the correct installation of DPF injector seals on 2016 and newer Medium Duty Low Cab Forward (LCF) trucks. This essential tool kit ensures proper seal placement, prevents damage during installation, and helps maintain optimal injector performance.
The J‑46911 kit includes a Seal Protector, Seal Pusher, and Seal Sizer, each engineered to guide the seal into position without tearing or overstretching. The Protector fits over the injector tip, allowing the new seal to slide smoothly up the ramp. The Pusher drives the seal into the injector groove, and the Sizer compresses the seal to the precise diameter required for proper injector installation.
Correct seal installation is critical—improperly sized or damaged seals can lead to injector leaks, reduced performance, and costly rework. The J‑46911 tool set ensures accurate, repeatable, and OEM‑compliant results every time.
